Mt Amagoi (1068m), Numata City, Gunma Prefecture, Monday, May 5, 2025

I found out about this mountain, situated between Mt Hotaka and Mt Akagi, while contributing to the Japanwilds hiking map for Tanbara Highland. Apparently most hikers go up and down the same route from the parking on the south side, but looking online, I saw it was possible to descend on the west side and end at Kawaba Den-en Plaza, one of the most famous roadside stations in Japan. Although the hike seemed somewhat short, the panoramic view from the summit motivated me to travel to a faraway and yet unexplored area.

To get there, I’d ride the Joetsu Shinkansen to Jomon Kogen, and from there, ride a bus to a stop located one hour on foot from the trail entrance. For the return, I could catch a bus from the roadside station for Numata station, and there, ride the local Joetsu line to Takasaki station where I could catch a shinkansen for the short ride back to Tokyo. If time allowed, I could take a hot bath at Kawaba Den-en Raku Raku onsen before heading back. The weather was supposed to be sunny and warm, typical weather for May. I was looking forward to a relaxing Golden Week Hike and getting some new views.

Dirt Road at the Start of the Hike

Heading to the Sky

It was already quite warm as I got off the bus in the middle of the countryside. Since it was 11am, I started almost right away, up a winding road through fields and then forest. Half an hour later, I passed Ishiwari-zakura (石割桜), a massive cherry blossom tree I had hoped to catch in full bloom, but was already well into green leaves stage. After passing a junction where a steep road led down to a parking lot on the left side, I arrived at the official start of today’s hike, a dirt road hugging a deforested mountain side.

Mt Akagi’s Western Flank

A Pleasant Start to the Hike

I was excited to get a sweeping view at such an early stage: to the left was Mt Akagi, it’s long western flank clearly visible from this angle; on the right side, I could see Mt Komochi, surrounded by Mt Haruna and Mt Okono in the back, bring back good memories from hikes from over ten years ago. After a pleasant panoramic along a mostly level road, reminiscent of alpine hikes, I re-entered the forest around 1230, passing between a couple of towering red pines.

Looking back at Mt Haruna before Entering the Forest

I was stunned by the profusion of the new green of Spring in all directions; at one point, I witnessed a flurry of white blossoms blowing across the path, coming from some unseen mountain cherry tree. After a short switchback section, I reached a flat section along a saddle on the mountain. Although I was now completely in the forest, I enjoyed the peaceful surroundings, few hikers venturing on this not so famous peak.

The Flat Top of Mt Mitsumine with the the Peaks of Joshin’Etsu in the Back

After a short climb, I arrived at a flat space, mostly free of vegetation on the southwest side, the top of Mt Amagoi (雨乞山あまごいやま amagoi-yama), a fairly common mountain name in Japan, meaning “begging for rain”, something I definitely didn’t want to do, today being a perfect blue-sky day. Mt Akagi took up most of the south side; southwest was Mt Komochi again; I now had a new view on the west side where I could see the flat top of Mt Mitsumine, with behind, the highest peaks of the Joshin’Etsukogen National Park, most of them still in their winter clothes. Mitsumine is a popular paragliding spot and I happened to see a paraglider drift through the sky. It was exactly 1pm, so I sat on a bench and enjoyed lunch with a view.

After lunch, I tried to match all the Joshin’Etsu mountains using the summit information board, since only the Tanigawa range on the very right was instantly recognisable ; apparently on clear winter days, one can also see the Chichibu Mountains, the South Alps and Yatsugatake. Although trees blocked the views in other directions, I was able to spot the still snowy top of Mt Hodaka through some bare branches on the north side, a preview of my upcoming descent. A little before 2pm, I set off again, down a steep path on the west side.

Heading down the Western Side of Mt Amagoi

Here, the trail was buried under dead leaves and would have been hard to follow, if it weren’t for rope attached to nearby trees. I soon emerged from the trees and was greeted with a spectacular view on the northwest side. To my right, I had a better view of the snowy summit of Mt Hotaka, framed by mountain cherry trees. On the west side, I could once again see Mt Mitsumine and Mt Tanigawa. As I descended this valley surrounded by snow-capped mountains, I almost felt like I was walking in the Swiss Alps.

Emerging from the Trees on the Northwest Side

Mt Mitsumine (left) & Mt Tanigawa (right)

I was following a narrow ridge with tall red pines on my left and a deforested area on my right, allowing for plenty of views along the descent. I soon turned left, onto a path between two rows of fir trees, the end of the scenic descent. After a short while, I entered a mixed forest, and after a short section where the only trace of a path was again a helpful rope hung between trees, I reached a winding forest road heading down through tall cedars.

A little before 3pm, I reached the valley bottom next to a small stream. From this point, the level trail headed west in a straight line through forest. Very soon, I reached a wildlife net and a paved road where I turned left, heading south, through orchards and fields. As I approached a busy road, I had some good side views of today’s mountain, on the left side.

Walking along the Valley Bottom

During the entire descent, I saw no other hikers, as most people seem to visit this mountain by car. At 3h30, I reached Rakuraku onsen, meaning “comfortably”; one hour later, after a quiet hot soak, as most people seemed to prefer to spend their time at the neighbouring roadside station, I hopped on the nearly empty bus for Numata station. I was grateful to have found this hike, and to have been able to visit in this season; it is certainly one of the hidden gems of Gunma.

Mt Arikasa (873m), Nakanojo Town, Gunma Prefecture, Sunday, May 8, 2022

I wanted to squeeze in one more hike before the end of Golden week after recovering from the three previous ones. I decided to visit Nakanojo in Gunma, as it was an area I was interested in exploring more. I found a three-hour loop in a booklet I picked up on my last visit; this mountain wasn’t in my guidebook, nor shown on any of my maps, so I had to rely on information online. I would ride the shinkansen to Takasaki, where I would transfer to the Agatsuma line. After getting off at Nakanojo, I could catch a bus for Sawatari Onsen, the last stop on the line. The hike itself went around a rocky, isolated peak, also a popular climbing area, with a short round-trip to the flat top on the south side. I was concerned about that part, as it included chains and ladders; I would have to proceed with caution going up, and even more on the way down. The weather was supposed to be clear and not too hot. I was looking forward to going to Nakanojo again and visiting a new hot spring town hidden in the mountains of Gunma.

It was a blue sky day as I rode the shinkansen, and then the local train, to Nakanojo. Around 10h30, I boarded a bus for Sawatari Onsen (沢渡温泉), my first time to ride this line. I got off at the last stop, just past the hot spring town, near a bridge over the Sawatori river. Straight ahead, I had a good view of today’s mountain, an isolated peak jutting straight up out of the green forest. As I got ready at the nearby Seseragi Park (せせらぎ公園), I wondered how the trail would get to the top of the rock. At 1130, I set off along a road, and half an hour later, just before another bridge over the river, I turned left onto a forest road.

Forest road leading to the West Entrance

Interesting rock formation in the middle of the forest

I had some more impressive views of today’s climb, after arriving at a fork in the road. I took the right branch for the West Entrance (西口), which I reached a little after noon. I followed the trail straight up the mountain side and soon reached an open shelter in the middle of the forest. I took a short break and then continued on my way. At 12h30, I reached a turnoff for a natural rock formation, resembling a dolmen, visible through the trees on the right. After circling it and peering through the gap in the middle, I resumed my climb.

Start of the climb up “The Ladder”

The path turned right under some cliffs, the higher parts hidden by the green canopy of the trees ; here and there, I spotted chains used by rock climbers. At 1pm, I arrived at the East Entrance (東口) trail junction and the start of the roundtrip for the summit; I followed the path as it wound clockwise around the steep summit and passed a funny sign informing me that I was at an elevation of 888 meters, read as “Hahaha” in Japanese (ハハハ). Very soon, I was walking through a rocky area with views to the west through the trees; looking down, I realised I was at the edge of a cliff.

The very green East Entrance

I had also reached the chain and ladder section, called “The Ladder” (梯子); I climbed with care, but near the end I couldn’t advance while keeping three points of contact at all times; after some consideration, I finally found a way, and after fixing it in my mind for the return, continued with the ascent, now in a counter-clockwise direction. A few minutes later, I reached a rocky outcrop from where I had a view south of forested hills. Soon after, I arrived at the flat top of Mt Arikasa (有笠山ありかさやま arikasayama), a Gunma 100 famous mountain. I couldn’t see anything through the trees, so I headed back almost at once; I got down “The Ladder” safely, and since it was 1h30, found a good place to sit for lunch, at a safe distance from the cliff edge. Afterwards, I continued along the trail, now heading downhill towards the East entrance.

The well-maintained “promenade” above Sawatari Onsen

View of Sawatari onsen, a secret hot spring resort in Gunma

As I passed under the cliffs, I could hear the voices of climbers echoing above. I walked along the forest road to the junction I had passed earlier in the day, and then made my way back to Seseragi Park. Since it was just past 3pm, I decided to follow a “promenade” (遊歩道), a short, well-maintained trail on the hillside above the hot spring resort. It took me past a small shrine surrounded by bright red Azalea, with good views of Mt Arikasa and Sawatari Onsen. At 4pm, I dropped by Ryumeikan (龍鳴館), for a quick hot bath before catching the bus back to Nakanojo. Once back in Takasaki, I rode the green car of the Shonan-Shinjuku line back to Tokyo, bringing to an end a series of successful golden week hikes.

Jomine Park (498m) & Sanbaseki Gorge, Kamikawa Town & Fujioka City, Saitama & Gunma Prefectures

As I was looking for a way to continue my exploration of western Gunma, I found a section of the “Kanto Fureai no Michi” surrounded by four previously climbed peaks: Mt Jomine, Mt Mikabo, Mt Sakura and Mt Yokogai. The highlights were a viewpoint of Kanna lake and a river gorge; on the downside, the route followed paved roads instead of hiking paths. I wasn’t worried about access, since I had traveled to the area before. It would be a short hike, so I could leave later than usual. Although most of the hike would be inside Saitama, except the river gorge, I would be arriving and leaving via Gunma. The weather was supposed to be fine all day, and although I wouldn’t be summiting any mountains, I was hoping to get some good views along a hidden valley close to Tokyo.

Kanna lake and Shimokubo dam from Jomine Park

I had only a few minutes to transfer to the bus after arriving at Shinmachi station around 10h30. I got off one hour later, a couple of stops before the dam and the lake, seemingly in the middle of nowhere. I could see Jomine park and the dam straight ahead, so I got my bearings easily. After getting ready, I used my phone GPS to find my way to the bottom of the river valley. I crossed the bright red Tosenkyo bridge (登仙橋), also crossing into Saitama prefecture at the same time, and walked up the road opposite, alongside a small river.

Looking downstream (left) and upstream (right) from Tosenkyo Bridge

I soon spotted a small path next to the river and immediately switched to it so that I could better enjoy the sight and sound of the rushing water. I was now walking inside Tobagawa river park (鳥羽川河川公園). At 1pm, I rejoined the road, which climbed steeply and away from the river. Half an hour later, I reached a junction: straight ahead the road continued to the top of Mt Jomine, 4km away and 500m higher; however, I took a sharp turn to the right, along a gently rising, almost flat road.

I now had my first good view of the day: looking east, I could make out the top of Mt Yokogai which I had climbed just one month ago; huge cumulus clouds were crowding the sky to the south, and although rain was forecasted closer to Tokyo, the surrounding mountains were still in the sun. At 2pm I arrived at Jomine Park (城峰公園) and had lunch at the observatory overlooking Kanna lake (神流湖) to the north. Beyond it, I could see the rounded top of Mt Sakura.

The only hiking path on this “hike”

Cloudy weather to the south over Chichibu

After lunch, I made a quick tour of the park and found another less impressive viewpoint on the other side, and at 3pm, I headed down a wide road leading to the dam. After only a few minutes, I reached a shortcut following a log staircase overgrown with grass; it was the first and only hiking path of the day. Less than 10 minutes later, I was back on the road. At 4pm, I was on the pedestrian road that ran along the top of Shimokubo dam (下久保ダム).

The blue-green water of Kanna lake

Kanna lake, a hidden gem

This was the second highlight of the day: looking west, I could see Kanna lake sparkling under the afternoon sun; turning around, I could see the impressive ravine through which flowed the Kanna river. After walking up and down the dam, I headed down into the deep valley on a road closed to traffic; 15 minutes later, I was at the entrance of the Sanbaseki Gorge (三波石峡). Although the riverside path is no longer in use, I could approach the river via four small paths situated at regular intervals along a road.

Each riverside spot was like straight out of a fairytale: at the first two, the clear water rushed through huge boulders, 48 of which have names; at the last two, the light-green water flowed lazily under grey cliffs. The sinking sun shone down the valley through the leaves and onto the water; a slight breeze blew occasionally, its coolness welcome on a warm day. I took a short break at the third spot and enjoyed this magical secluded place.

It was now past 5pm and my bus was due in half an hour. I continued along the road at a fast pace and soon arrived back at the red bridge which I had crossed five hours ago. Huge grey clouds had now spread above, and it seemed like it could rain at any moment. I quickly climbed out of the valley back to the bus stop. One hour later I was at Shinmachi station, from where it was a 90 minute train ride back to Tokyo.

Mt Koo (550m), Mt Hinata (482m) & Mt Taka (420m), Fujioka City, Gunma Prefecture [Ontake Trail]

After visiting Mt Sakura the previous year, I really wanted to do another hike in the same area. I knew there were two more short trails to the north, making them suitable for the winter. However, looking online, there seemed to have few views, and I thought it would be nicer to visit during the new green of spring. I chose the better maintained Ontake trail, over the more adventurous Kamatori trail. By starting with Mt Koo, a separate peak connected by a short walk on the road, I could extend the hike to 3 hours. These trails weren’t shown on my hiking map and weren’t mentioned in my hiking guides, so I had to rely exclusively on information found online. Getting to the start of the hiking trail would require a combination of two local trains and a bus: not the easiest route, but with plenty of time between connections, it seemed problem-free. The weather forecast was “cloudy with sun later on”; although the views were supposed to be scarce, the new green of spring always looks better in the sun, so I was hoping for some sunlight on this hike.

Start of the “2000-step staircase”

The sky was grey and gloomy during the first part of the my trip. However, while switching to the Hachiko line, the clouds parted, and after arriving at Gunma-Fujioka station at 10am, the sun was shining. Instead of a bus, I got on a mini-van, a common form of public transport in this part of Gunma. A little before noon, I got off at the last stop, called “nisen-kaidan-iriguchi” (二千階段入口), meaning entrance to the 2000-step staircase. Looking west, I could make out the foothills of Mt Mikabo, its top half lost in the clouds.

View from the top of Mt Koo

It certainly didn’t feel like 2000 steps: it took me just five minutes to reach the the summit of Mt Koo (子王山こおうやま meaning small king), completely in the trees. Walking north and down a few meters, I reached an opening in the trees, where I had a view of the Kanto plain with the tall buildings of Takasaki city to the northeast. I should have been able to see Mt Haruna, Mt Akagi and the Nikko mountains, but the weather still wasn’t good enough. I had an early lunch before setting off again.

The beautiful spring green of Gunma

Start of the Ontake hiking trail

I went down some steeps steps on the other side, and then followed a forest road round the mountainside, arriving back at my starting point 15 minutes later. I walked east along the countryside road till I reached the entrance to the Ontake trail (御嶽コース). The trail descended for a short while, before crossing a metallic bridge and then heading up a ridge. Soon, I was walking along a level path through the forest. At 1h30, I reached the narrow summit of Mt Hinata (日向山 meaning in the sun); oddly enough, despite being surrounded by trees, the summit marker was…in the sun.

By the afternoon, the good weather had prevailed

The trail continued up and down, with the steeper sections helpfully equipped with rope; half an hour later I was at the top of Mt Ontake-Taka (御嶽高山), once again hemmed in by the trees. Past the summit, the path started to descend and at 2h30, I emerged onto a forest road. At 3pm, I reached the road and the end of the hiking trail. It walked ten minutes to the Takayama-sha Ruins bus stop, next to a world heritage site, where I caught the mini-van back to Gunma-Fujioka station. It took only a few minutes to connect to the Shonan-Shinjuku line, after which it was a 90-minute ride back to central Tokyo.

Ken-no-mine (1429m) and Mt Tsunoochi (1393m), Takasaki City, Gunma Prefecture, October 2020

I first spotted these two mountains while hiking Mt Hanamagari in January 2016. Before I could attempt them, there were a couple of things I needed to figure out. First, the trail between the two peaks was a dotted line on my map. After checking online reports by other hikers, apart from being super steep, it didn’t seem to be dangerous. Next, as usual, access was a real headache. My guidebook recommended going by car and hiking up and down from Hamayu Sanso (I had stopped there for a bath once after climbing Mt Asamakakushi). However, I felt it would be more exciting to do a traverse instead. I would take a taxi from Yokokawa station to the parking area for Kirizumi onsen and finish at Hamayu Sanso on the other side. The main drawback was that there were no buses back to Takasaki on the weekend (only on weekdays, strangely enough). I resolved to skip the hot bath, and walk ten kilometers from the end of the hiking path to the closest bus stop, a place called Gonda. I just hoped that I would make it in time for the last bus of the day at 4pm, or I would be stuck there. The weather forecast was good, and the autumn leaves would still be at their peak up in the mountains.

After getting off at Yokokawa station for the second time this month, I was alarmed to see no taxi waiting outside (I hadn’t reserved one). I called the taxi company, and they said they would send a car over at once. Along the way, the driver pointed out the Shinkansen tracks, exiting the side of the mountain before quickly reentering it on the other side. I had hoped to see one zip by above us, but no luck. The taxi dropped me off at the parking below Kirizumi Onsen (霧積温泉). At 10am I was ready to start hiking. First I followed the path leading to the hot spring hotel. Twenty minutes later, after merging with a forest road, I turned right onto the hiking trail.

The trail hugged the south side of the ridge

The trail rose gradually through the autumn forest and soon reached a fork. The main trail for Mt Hanamagari went left, but today’s mountain was along the right branch. The trail crossed a flat area and became faint; I had to find my way following the pink ribbons attached to the tree branches. I soon reached the main ridge separating Annaka and Takasaki cities. The next section turned quite adventurous. The path followed the top of the ridge for a short while, then, as the ridge narrowed, dropped slightly, and cut across the south side, staying just inside the Joshin-Etsu-Kogen National Park. There were some ravines to the right; at one point, the path hugged the base of a cliff, and I used the chains attached to the rocky face to keep my balance. Views were sparse, but the autumn leaves were stunning. There was no other hikers and I enjoyed the silence of the forest.

Mt Asamakakushi from Kennomine

The ridge widened and welcomed the path back. I made my way up a short slope and at 11h30, I had my first views of the day. Opposite was Mt Asamakakushi, and to the left was Mt Hanamagari, with Mt Asama looming behind. In the background, I could make out the peaks of the Joshin-Etsu, still free of snow. There were more clouds on this side and the mountains played hide and seek in the shadows making it difficult to get good photos. I walked a couple of minutes along the ridge, and reached what I judged to be the summit of Ken-no-Mine (剣の峰けんのみね kennomine) – the summit marker was broken in half, and the mountain name was illegible. I decided to continue without a break. The next section was the dotted section on the map, and I was keen to get it behind me.

The autumn leaves were at their peak

At first, this steep slope didn’t seem like a big deal. I rushed down, occasionally grabbing tree branches to keep my balance. Soon the terrain became so steep that the trail simply vanished. Once again I had to rely on the pink ribbons. They were spaced far apart, and the path didn’t simply go straight down: it twisted and turned, around boulders, over bundles of tree roots, down narrow gullies, and roped sections followed roped sections. I had to stop several times and carefully scan the the whole mountain side to pick up the trail. The last thing I wanted to do was head down the wrong way and have to climb back up. Although the path was dotted on the map, I was surprised that anyone would dare turn this into a hiking path. My guide book suggested going up and down this trail, and I was thankful for having chosen the traverse instead.

Mt Hanamagari, left, with Mt Asama behind and on the right

At noon, it was with relief that I reached the pass between the two mountains. I was now back on a proper hiking path. I would do a roundtrip to the next peak, before heading down the mountain. It took me about twenty minutes of steady climbing, through a festival of autumn colours, to reach the top of Mt Tsunoochi (角落山つのおちやま tsunoochi-yama), a name that could be roughly translated as “dropped antlers mountain” – I didn’t see any. The summit area was narrow, covered in trees and bushes, and included a small shrine and shinto gate. If I stood near the highest point, I could get a good view of the whole of northern Gunma, all the way to Mt Tanigawa and Mt Hotaka. The view to the south wasn’t as good, but I could still make out the Kanto plain through the trees.

The mountains of Northern Gunma

One glance at the time told me that I would have to keep my lunch break short. I had a little over 3 hours to get off the mountain, and walk ten kilometers to the bus stop. After taking all the necessary photos, I retraced my steps to the pass. There, the trail doubled back along the steep side of Ken-no-Mine. I saw some impressive cliffs, and had to tackle a couple more chain-lined sections. Soon I was walking down a broad river valley through beautiful forest. Even though I was no longer inside a National Park, I felt this part could have been included. Suddenly, I was off the trail. I walked back for a few minutes, and thanks to the pink ribbons, found the path again, along a dried-up rocky river bed. Thirty minutes after leaving the summit, I reached the end of the hiking trail.

Hiking down in the late afternoon

From there, I walked down a forest road for another half an hour before I reached a prefectural road. It was an enjoyable walk that I did at a fast pace, crossing a beautiful mountain stream several times. One of the reasons I opted to walk to the bus stop was that according to my hiking map, there were good views along the road. I wasn’t disappointed. It also said there were monkeys in the area, but I didn’t get to see any this time – perhaps a good thing since I didn’t have much time to spare. After about an hour an a half of fast walking I reached the bus stop a few minutes before the bus was due. I had to change buses once on the way to get to Takasaki, with a one hour wait in-between. Luckily, the bus arrived early, and I was able to catch the previous bus, meaning I got back to Tokyo earlier than expected – always welcome after a long hike!

Hiking the Nakasendo: Usui Pass to Yokokawa Station & Megane Bridge, Gunma Prefecture, October 2020 [2023 Map Available]

I had hiked this Gunma section of the Nakasendo (中山道) in January 2015 using the Tokyo Wide Pass; it’s less well-known than the section in the Kiso valley. I thought it would be interesting to redo it in a different season. First, the autumn leaves would be at their peak around the start of the hike. Next, I hoped that in the warmer weather I would be able to see monkeys along the way. I also wanted to add a side trip to the nearby Megane Bridge. Finally, I was looking forward to using the hot spring near the end of the hike, which was closed on my last visit . Instead of taking the Shinkansen to Karuizawa, I decided use a combination of train and bus, longer but cheaper; then, to make up for the later arrival, I would take another bus up to Usui Pass instead of walking. The forecast was cloudy with a hope for sun, but apart from Usui Pass, there were few views along the way.

View from Usui Pass (photo taken in January 2015)

The trip to Karuizawa went smoothly: I had good views of Mt Myogi from the train, and saw some nice autumn colours from the bus. From Karuizawa station, I walked to the bus stop of the Red Bus (赤バス aka basu), a small seasonal sightseeing bus. There were few passengers and I was able to enjoy the view from the front of the bus as it zipped through old Karuizawa, and then zoomed up a narrow mountain road to Usui Pass (see video). The clouds were in and the view wasn’t great; in consolation there was a resplendissant Japanese maple tree in orange and red. I finally set off on the Old Nakasendo Highway (旧中山道 kyu-nakasendo) around 12:30.

River crossing along the Nakasendo

After an eroded downhill section, I crossed a small stream, and then followed a narrow level path till it merged with a wider trail heading down again. It was around here that my map reported monkey sightings, so I kept my eyes open and ears peeled. During the Meiji area there also used to be a village around here, and here and there its remains could be seen, making this part of the hike somewhat spooky. Past a rusting bus on one side of the path, and a rotting house on the other side, I heard strange noises coming from the treetops. At first I thought they were monkey noises, but it turned out to be some kind of bird call. I got lucky a little further. After going a little off the trail to investigate some suspicious noises, I stumbled upon a troop of monkeys moving through the forest. Unlike the ones from Okutama lake, these ones were shy and scattered at once, except for a large male, coolly walking away through the trees (see video).

The path followed the natural folds of the mountain

After the excitement of seeing monkeys (second time this year), I resumed my hike along this Edo period highway. The road became level again, and offered glimpses of mountain ridges and river valleys left and right. There were occasional white signs in Japanese, explaining various natural and historical landmarks. Most of this hike was inside the Joshin-Etsu-Kogen National Park and the surrounding nature was wild and beautiful. Soon the road narrowed and turned into a hiking path again; it started to twist and turn, following the natural folds of the mountain ridge as it slowly descended into the valley. For a short while, I walked above a mountain stream tumbling down a small narrow valley. I took a moment to observe a large butterfly return obsessively to a curiously shaped-flower, and feed greedily on its nectar (see video).

At 2h30, I finally arrived at a small rest house. I remembered it well from my previous visit. The guest book, slightly moldy despite it’s plastic casing, was still there, sadly devoid of English entries since spring this year. I found my old entry from 5 years ago and added a fresh one. The path turned rocky and started to descend in a series of switchbacks. On my winter hike I had good views of Mt Myogi and Yokokawa town around here; now, however, the view was blocked by tree leaves. Around 3pm, I reached the base of the mountain, and arrived at the modern road connecting Karuizawa and Yokokawa. On the other side and down some steps, I found myself on the “Apto Road” (アプトの道) that went through a tunnel under the road. This pedestrian road is named after the “Abt system”, a rack system, used by the old Usui line to transport passengers up the mountain side to Karuizawa from the middle of the Meiji era till 1963.

It was getting late but I decided to stick to my plan of exploring this road. Keeping to the day’s theme, it passed through several tunnels, some pitch black and some glowing orange from the interior lighting. Half an hour later at the end of the longest one, I arrived at the highlight of the day, Megane bridge (めがね橋 megane-bashi), the longest brick arch bridge in Japan. It was wonderful to walk on this marvel of Meiji era engineering. Apparently the autumn colours are spectacular here, but I was a couple of weeks early. Past the bridge, the road ducked into yet another dark tunnel. It was possible to continue a few more kilometers to an abandoned railway station, but it was getting late, and I decided to head back. The road ran straight and slightly downhill to Toge-no-yu hot spring which I reached in less than half an hour.

After a speedy hot bath, I was ready to continue. By now it was 5h30 and already pitch dark outside. It had also started to drizzle. I was still 3 kilometers from the train station. I had walked it before – the road was straight and paved so there was little risk of getting lost or hurt. I briefly considered calling a taxi, but what better way to finish a spooky hike than a walk in the dark past an abandoned railway station? On the way, I discovered that my headlight only worked intermittently. I hurried past the disused Maruyama station building on the left, a darker shadow among the shadows. At 6pm, I passed the closed Annaka Tourist information office, and was finally walking under street lights. I reached the still-in-use Yokokawa station, well in time for the return train to Takasaki and Tokyo.

Tanbara Highland (1200m), Numata City, Gunma Prefecture & Bear Sighting

I had been to Tanbara highland in May 2018 (also spelled “Tambara”), so I thought it would be the perfect place for some easy hiking during the rainy season. Since I had already been to the highest point, Mt Kanomata, this time I decided to take a different trail and skip this summit. This would make for a slightly shorter hike which was good, since this time I was driving there and back myself (it’s also possible to get there by bus). My main concern was the temperature – would it already be too hot and humid to hike comfortably?

Tanbara Lake, seen from ski slope, turned grassy field

I arrived at the Tanbara Center house 玉原センターハウス around 12h30. Contrary to my expectations, the air felt a little chilly and a few raindrops were falling; however, the sun was just coming out from behind the clouds. I set off the along the same trail as my previous hike, heading gently uphill through a beautiful beech forest and following a small bubbling stream. Just before arriving at the Tanbara camping ground, I turned left along the road towards the Lavender Park in bloom from next month only. Now, however, the flowers were still closed, and the area was deserted.

The Tanbara Lavender Park

I walked up one of the paths among the flowerbeds to a small observatory. It had a bell that one can ring to scare away any bears that may be lurking nearby. I gave it a good ring. After climbing down, I spotted a black shape out of the corner or my eye. It was about a hundred meters away on the edge of the ski slope (Tanbara is a ski resort in the winter months). Using the zoom of the camera, I was able to ascertain that this was in fact a bear cub. It seemed unperturbed by the noise of the bear bell, but a few seconds later it ran off into the forest. This was my fourth bear sighting, and it had been a while since the previous one, so this made my day.

Tanbara is mainly known as a ski resort

I headed back down, and continued along the hiking trail up into a forested area between two lavender zones. Unfortunately, after a few minutes, the trail became so overgrown with bamboo grass that I had to give up . Even though it was indicated on the maps, it was obvious that the trail wasn’t much used, most people preferring the direct route to the summit. I decided to make my way back to the start of the hike, and turn right along the the bird-watching route 探鳥ルート so that I could at least reach the beech flats ブナ平, one of the highlights of the hike (I didn’t see any birds though).

The Iris flowers were in full bloom

Around 4pm, and somewhat behind schedule, I was finally walking on a level path among the beech trees. This is one of the rare places with a mostly flat trail high up in the mountains, so it’s perfect for beginners. Soon, I turned left, down the river source route 水源ルート, ending up at Tanbara Marsh 玉原湿原 around 4h30, another of the highlights of this hike. After crossing the marsh on wooden planks, I emerged onto a road (closed to traffic), and I was back at the parking lot just before 5pm. Even though I couldn’t do the hike exactly as I had planned, I was still able to hike for around 5 hours through beautiful nature in good weather. I was also relieved that the temperature and humidity had turned out to be perfect for hiking!

Mt Sakura (591m), Fujioka City, Gunma Prefecture, Saturday, February 29, 2020

Unlike my other hikes, this one took me up a mountain I hadn’t known existed till recently. I found out about it during my research on the Gunma Fureai no Michi trail. I saw it again the previous week, on the map of the Gunma-Fujioka area outside the station, and I noticed that a loop hike was possible using local trails. Since it wasn’t mentioned in my “Mountains of Gunma” guidebook, I found all the necessary information on the Fujioka City website.

Mountain panorama, less than 100km from Tokyo

Although today’s starting point was less than ten kilometers away from where I started last week, it was in a different valley, so I needed to take a different bus, from Honjo station, a few stops before Takasaki. The nearly empty bus took me to Onishi 鬼石, a charming little town in a valley encircled by mountains. The main street was lined with wooden lanterns, called “joyato”, a kind of nightlight, giving the town a traditional feel. I’d love to see the city in the nighttime.

Same view but in the afternoon

I chose to go up via the Onishi Route. It took me thirty minutes along a small road to reach the start of the hiking trail. I wasn’t sure that I was in the right place because the signpost had fallen down, and was lying on the road about fifty meters away, an ominous sign. I decided to push ahead anyway. I was following a fairly new forest road as it wound up the mountain. There were no other signposts, but the general direction seemed to match my map.

Solar panels are everywhere in the Japanese countryside

Looking Southwards to Chichibu

At 11am, I emerged into a clearing that was covered with solar panels, the reason for the new forest road. To the West, I had a view of the Kanto plain, and to the East, I was able to spot my target mountain, still relatively far away. I still wasn’t 100% sure I was on the hiking trail. I continued on the forest road down the other side, and it was with relief that I finally spotted a hiking signpost. I now continued with a spring in my step, past more solar panels, and onto a level forest road following the side of the mountain through the forest. From this point, signs and signposts were a lot more frequent. I have mixed feelings about walking on forest roads. They are easy to walk, but since they are wide and mostly straight, you don’t have the constant changing scenery you get on the smaller trails.

Just after noon, the trail intersected briefly with the road going to the top of the mountain, but then continued as a steep path next to an interesting wooden house. As I passed in front, the owner, a man in his sixties, came out. We started chatting, and he invited me into his home for some “ocha”. For once, I wasn’t behind schedule, and since I was curious about his house, I decided to accept. We had an interesting chat over tea and “dorayaki”. Finally, it was time to go. He offered to drive me to the park near the top of the mountain, since the last part was mainly on the road. It seemed like a good idea, and it allowed me to make up some time.

The area is famous for sakura in the spring, and autumn

The views are better when walking around the side

At 1pm, I was standing at the entrance of Sakurayama Park, famous for its winter cherry blossoms or “fuyuzakura”. Apparently, you can enjoy sakura twice a year. However, at the end of February, the buds were still firmly closed, and the park was almost deserted. I started up one of the staircases leading to the summit, and soon reached the top of Sakurayama 桜山. Unfortunately there was no summit marker and no view. I went down the other side, where there was a grassy space with benches and a good view – a great place for a late lunch. From right to left, I could see Mt Mikabo, one of the highest mountains in the area, Mt Jomine, at the edge of the Chichibu basin, and Onishi town.

It was already past two o’clock, and time to continue my hike. Rather than walk back up, I followed a path around the mountain, hoping to get better views. By the time I was back at the entrance of the park, the sunny weather from the morning had turned cloudy. For the descent, I chose the Yashio Route, ending at Yashio Onsen 八塩温泉. It started out as a mostly level forest road, similar to the way up, but after half an hour, it turned into a nice little hiking trail through the woods. There were no other hikers, so it was very peaceful.

Nice hiking trail on the return

Walking between the cedar trees

After another thirty minutes, I reached a great viewpoint of the Kanto plain, just past a shrine to Benzaiten. By now, the visibility was a bit hazy, but it should be spectacular on a clear day. I continued down, and reached the end of the trail and the road after 4pm. I walked ten minutes to Sakurayama Onsen, where I had a quick hot spring bath, before catching the bus back to Shinmachi station and the train home.

Hiking the Kanto Fureai no Michi 関東ふれあいの道

It was my first time to do a full hike along the Kanto Fureai No Michi, also known as the Metropolitan Area Trail, following section four of the Gunma portion. I chose it because it seemed to mostly follow a hiking path through the mountains. Also, it was in an area I had never been to before, but that I had seen many times while taking the train to Takasaki.

Castle-shaped Observatory near the summit

In Takasaki station, I transferred to the Hachiko line, a small railway running parallel to the Chichibu mountains, all the way to Hachioji. A sign told me that it was leaving from track 3, located between tracks 2 and 4. That seemed obvious, but it also indicated that it shared the same platform, seemingly impossible. However before I could inquire, I spotted track 3 starting at the end of the platform, and it was with relief that I boarded the train. It’s never easy to handle these complicated train situations first thing in the morning!

The plum blossoms were out

I got off at Gunma-Fujioka station just a few stops away, and waited half an hour for the mini-bus that would take me to the Kami-Kashima bus stop. I was of course the only passenger. The bus headed West following the Ayu river. I got off shortly after 9am, and found myself standing next to the road in a narrow valley under blue skies. It was hard to believe that I had l left the heart of Tokyo only a couple of hours earlier. I quickly located the start of the trail, and made my way up the side of the valley. I passed plum blossom trees, solar panels, and slightly startled locals. Turning around, I saw the rounded peak of Mt Mikabo, which I climbed in 2016. Soon, I was walking along a dirt road through the forest, and I reached Konashi Pass 小梨峠 (584m) just before 10h30.

First views of Mt Haruna past Konashi Pass

At the very right, Mt Shirasuna, which I climbed last year in October

From there it was a long walk downhill into the valley on the other side. At the bottom of the wide valley was the Joshin Dentetsu line, which connects Takasaki with Shimonita, and Tomioka city. This part was very peaceful, and had some good views of Mt Asama, Mt Haruna and Mt Akagi. In the background were the snowy peaks of the Joshin-Estu. There was some trail damage here, probably due to last year’s typhoons, minor at first, but more significant lower down. At one point, I had to clamber over some boulders and fallen trees. I hope that it will eventually get cleared up. As I walked down the valley, the forest road turned from dirt to paved, and ran parallel to a stream, and at 11h30 I emerged onto an asphalt road.

Good hiking trail past around Konashi Pass

No so good trail lower down

I followed the road for a while, before turning left onto a tiny hiking path, up a small forested hill. All too soon I reached another road leading down the other side, through what seemed like an abandoned hamlet. Just after the road started climbing again, I heard a crashing noise coming from the forest to my left. While I was trying to process what it could be, a stag with fully-grown antlers crossed the road a few meters ahead of me. For a few seconds, I remained rooted in place; I had only seen a stag close up once before, while hiking in the Koshu Alps a few years ago. I continued up the road, slowly gaining altitude, and spotted a small hiking path on the left. I decided to check it out quickly. It led me to a bench and a fantastic lookout point. The trail continued down to the base of the mountain. I decided to stop and have some lunch. Afterwards, I retraced my steps, and found that the hiking trail continued straight up the mountain. I decided to leave the road for a while, since I would meet up with it again near the top.

Direct hiking path to the summit

It was a pleasant hike along a sunny ridge. Through the bare trees, I could see the pass I had walked down earlier. The silence was broken by three successive gunshots, and I hoped they weren’t aimed at the stag I had seen earlier. At 13h30, I reached the top of Mt Ushibuse 牛伏山, a Gunma hundred famous mountain. Although the name means “cow sitting on the ground”, I couldn’t see any bovians nearby. There was a small shrine with a bell, a rest house and an NHK antenna. I gave the bell a ring, and then proceeded to the observatory at the top of a Japanese castle replica a few minutes away. I had great views of the Northern part of the Kanto plain and surrounding mountains. Behind, was the were the Oku-Chichibu mountains. Inside the castle were interesting pictures of birds of prey taken in the area.

In the background, the Tanigawa mountain range

It was starting to get late, so I started to head down the mountain. The first part was along hiking trails and a second part along a road. At 3pm, I reached Yubata Onsen. I had hoped to take a hot spring bath there, but unfortunately they had a reservation-only system, and the bath was already reserved till 4pm. The owner let me wait on the balcony in case the person left early, but it was not to be. Originally I had planned to take a bus back to the station but since I had some extra time, I decided to walk all the way back following the Fureai no Michi. There were some good views of Mt Haruna and the surrounding countryside. I reached Maniwa station around sunset just after 5pm.

Hiking in the Mikuni Mountains 三国山脈

This is another mountain that had been on my to-climb list for ages. One reason was access: buses to Nozori lake 野反湖 only ran on weekdays – strange since there is nothing there except a campsite. Another reason was that it seemed to be perpetually inside the clouds. It’s probably one of the rare mountains I’ve never been able to see, despite having made multiple trips to the area, the most recent about 3 weeks earlier.

Mt Shirasuna, cloud-free version

Three weeks ago, I had the opportunity to do a weekday hike, and with perfect blue sky weather before the arrival of yet another typhoon, I decided to tackle this two-hundred famous mountain of Japan. Once I started planning in earnest, another issue arose – it couldn’t be done as a day trip using public transportation. I needed to stay the night at a hotel near Shin-Maebashi station to catch the first train for Naganohara-Kusatsuguchi station. Luckily, I was able to book a decent room the same evening.

The path down with Mt Asamayama in the background

The day of the hike, I caught the first outbound train on the Agatsuma line. For some reason, the train was full of high-school students, who all got off at the same station, apparently to go to Kusatsu onsen. There didn’t seem to be any accompanying teachers, but I guess it was some kind of school trip. I recognised some of them on the train back. After getting off the train, I got on a tiny bus with just one other person. It reminded me of the bus that I used for Mt Mikabo. The ride was very picturesque, through villages and along river valleys. It was part of Gunma that I had never visited before. After more than one hour, we reached a viewpoint over the lake – the driver kindly stopped there for a few seconds so that we could take in the view. In the early morning sun, the surface was a beautiful blue.

The beautiful blue of Nozori lake

The last bus back was at 3pm and I only had a short six hours to reach the top and come back. I had gotten ready on the bus, so after confirming the time of the last bus back with the driver, I left without delay. The start of the hike was through beautiful forest, mostly birch and silver fir trees, but not much in terms of autumn colours. I met no other hikers, not surprising on a weekday. 90 minutes later, I got my first views of the lake and the entire Asamayama range emerging from the morning mist. Later on, I had some good views of Mt Iwasuge 岩菅山, another two-hundred famous mountain I hope to climb someday. Before I knew it, I reached the top of Mt Doiwa 堂岩山 2051m, completely in the trees, just before 11am.

Misty Asamayama – I was hiking the peak on the right side the previous month

From the summit, there were some glimpses of mountains to the North through the trees. However, a few steps beyond, just as the path started descending, I got my first glorious view of the day. The weather was still perfect and I could see the path ahead all the way to my target mountain, as well as the mountains of the Joshinetsu-kogen National Park to the North.

To the South, I could even make out Mt Fuji popping up behind the mountains of Oku-chichibu. I also spotted other hikers climbing the mountain so I wasn’t alone. My original plan was to go up and down the same way. However, since I had progressed quickly, I decided to do a longer loop hike that would end at the other side of the lake (the viewpoint the driver paused at). I was now at the fork of the trail, so I would need to retrace my steps later on, something I didn’t mind doing since it was all views from here on.

Mt Fuji, barely visible 150km away

I lost time admiring and photographing the great views, so I had to hurry during the final climb, and I reached the top of Mt Shirasuna 白砂山 a little after noon. Since I wanted to do the longer route down, I had to pull myself away from the great 360 degree views only after thirty minutes. North was Mt Naeba, East, the Tanigawa range, with Mt Sukai in the distance behind, South, Mt Akagi and Mt Haruna, West, Mt Asama and Shirane-Kusatsu, with the North Alps visible behind. By the way, the hiking path continues all the way to Mt Mikuni, but it’s necessary to stay in a hut along the way.

The path continues…some day I might return to walk it

I hurried back and reached the fork for the loop hike at 1h30. From here I followed a wide and grassy path southwards – I tried to run a bit, but the terrain was uneven under the grass, so I had to be careful. There were good views to my left but the right side was blocked by trees. I was surprised that even on this less traveled hiking path the signage was fairly new and in English. Eventually the path bottomed out and I found myself climbing again. With some effort I reached the top of Mt Hachiken 1953m 八間山 with forty minutes to spare before the last bus back.

Looking back at Mt Doiwa (on the left) and Mt Shirasuna (on the right)

After a couple of minutes rest, I set off again, the final stretch down to the pass above the lake. At this stage I was running most of the way. The ridge seemed endless and I was greatly relieved when the lake and pass appeared to my right. I made to the bus stop with ten minutes to spare. The bus was actually a little late, but according to another passenger, the driver had waited for me for a few minutes before departing. It was the same driver as in the morning, and since I had asked about the last bus he had assumed I would be coming down the say way (that was my original plan) – how kind of him to wait for me!
