Hiking on Mt Yatsugatake 八ヶ岳
I was hoping to climb one last big mountain in 2019, before the arrival of snow, and I had had my eye on the two Southernmost peaks in the Yatsugatake range for a while. Even though they are the closest to Tokyo, right between Yamanashi and Nagano, they’re challenging to climb as a day trip from Tokyo – Mt Tengu, further North, was possible thanks to the Hokuriku shinkansen. In the end, I decided to stay the night in Kofu and drive to the mountain; this way I could leave at dawn, and finish around sunset. I had to travel to Yamanashi and back by highway bus, since the trains weren’t running as usual due to damage by typhoon Hagibis. This was a blessing in disguise, since the bus costs half the price of the train, so I could recoup some of the cost of the hotel and the car.

On Thursday morning, the sky above Kofu city was foggy, but as I drove West along the highway, blue skies appeared overhead. As Yatsugatake came into sight, I got a shock: the top was white with snow! As I drew closer, I saw with relief that it was only the highest peak, Mt Aka (2899m), that was covered in snow, and today’s hike would be snow-free. I reached the Kannondaira parking lot (1560m) just before 8am – there were quite a few cars, even on a weekday. The first part of the hike, a gently rising trail through forest that was still green, was fairly easy. After half an hour, I reached a clearing with a good viewpoint of Mt Fuji sporting a brand new snow cap – a good place for breakfast.

The trail continued through thick forest, and after another half an hour I reached the turn-off for my first peak. A steep climb straight up the side of the mountain, with occasional views through the forest of the Kofu valley behind me, brought me to the bare and rocky top of Mt Amigasa 編笠山 at 10h30. The 360 degree view was one of the best I’ve ever seen while hiking.
From left to right I could see Mt Fuji, the Minami Alps, the Chuo Alps, Mt Ontake, Mt Norikura and the Kita Alps – all the highest were covered with snow. I could also see the entire Yatsugatake range stretching North, with in the center the matterhorn-like peak of Mt Aka. There were so many great pictures from this hike, that it was impossible to share them all here.

After a quick bite, I set off downhill just after 11am, towards a saddle where the Seinen Hut was located, just 20 minutes away. The last part was full of giant boulders, and it took some time since I had to step carefully from boulder to boulder, following painted yellow arrows. After that, I was climbing again through forest. Suddenly, I was above the treeline at around 2600m; there was a sharp drop on my left, and an impressive rocky outcrop towering in front of me.
Fortunately, there was a switchback path on the right, with helpful chains in several places. It looped around the back, and led up to what I thought was the highest point. Noticing that there was no summit marker, I turned around – the true top was behind me, five minutes away and just a little higher. Looking left, I could the impressive “kiretto” or mountain ridge, leading to Mt Aka.

Originally I had planned to go up and down the same way. However, I had made good time climbing up, so I decided to take a different and longer route down. I hurried past another hut to the highest point of my hike, Mt Gongen 権現山 – in fact the highest mountain climbed in 2019. I couldn’t actually get to the very highest point since it consisted of a bunch of huge boulders, but I got as high as I felt safe doing, and had the rest of the lunch while enjoying the view of Mt Fuji in the distance. Since a boulder was in a way, I couldn’t get a perfect 360 degree view. The weather was still sunny, with almost no wind. Despite the high altitude, and proximity of the snowline 200m higher, I was perfectly fine wearing just a base layer. At one point a cargo plane, probably from the Japan Self-Defense Force, flew past the summit (see video at the end).

I had to set off fairly quickly if I wanted to complete the hike before dark, around 5pm. First I headed down and back up again to Mitsugashira 三ツ頭 (2580m). Looking back, the view of snow-covered Mt Aka, wrapped in mist was breath-taking. By now, it was nearly 2pm and I needed at least a couple of hours to get back to my car, so I pulled myself away from the view, and descended into the forest. This was one of the nicest and easiest downhill hikes I’ve ever done. There were good views of my first peak, with orange larch trees around the base. One hour and a half later, I reached the Yatsugatake crossing path (“oudan hodo” 八ヶ岳横断歩道), part of a trail that circles the entire mountain range – something to try one day. From there, it was another thirty minutes back to the parking area along a mostly level trail, although the last meters were steep uphill – pretty tough after what was nearly an 8 hour hike! Fortunately, there was a hot spring at the base of the mountain, so I could have a good soak before making the long trip back to Tokyo.
Although it’s called the red peak, today it was partly white
I believe this was a JIETAI plane flying past the summit
