I wanted to do some more hiking on the Abukuma Plateau, since I had a great view of it the previous week. Although, I had exhausted all day trip options from my guidebooks, I found a promising peak by examining my maps, east of Mt Takahara and southwest of Mt Yamizo. The hike was up and down the same way and the highest point was next to a road and a parking lot, meaning I wouldn’t have the summit to myself this time. I could get there by taking the shinkansen to Utsunomiya, then take the local line to Nishi-Nasuno, and there catch a bus for Otawara City; on the return, I would do the same route in reverse. The weather was once again supposed to be sunny all day long, and so I was looking forward to exploring a new area and seeing some familiar mountains from new angles.

It was another perfect blue-sky day as I got off the empty bus a little after 11am. On the way to the trailhead, I stopped by a conveniently located 7/11 to buy some last minutes supplies, and was finally ready to start hiking just before noon. I went under a stone Shinto gate and walked up a long staircase, at the top of which I passed the lonely Atago Shrine on the left. I then followed the path surrounded by tall cedars, the winter sun filtering through the treetops. After some ups and downs, I reached an area clear of trees just before 1am.

To the west, I had a fantastic view of Mt Nasu, its highest peaks still covered in snow; looking north, I could make out the more discrete shape of Mt Yamizo, the highest peak of the Abukuma Plateau. After taking in the view, I continued along the gently climbing and easy to walk trail. Half an hour later, I emerged onto a road which I followed a short way before reentering the forest. Here, I encountered the steepest section of the hike: although short, it was a scramble, even in dry weather. A few minutes later I arrived at a open shelter.

Looking west, I had an excellent view of Mt Takahara, specks of white visible on its highest points. I soon moved on, and at the top of a grassy staircase, reached the summit of Mt Koteya (御亭山 こてやさん koteyasan). I had a view on the west side, stretching from Mt Tsubasa to the Oku-Nikko mountains, their tops hidden by clouds; in between lay the vast Kanto plain; on the opposite side, I could make out Mt Yamizo, just visible above the trees. It was nearly 2pm, so I sat on one of the benches scattered around the wide grassy summit for a lunch break.

It was more peaceful than I had imagined with only one other person venturing to the top from the nearby parking lot. After lunch, I made my way down to the road, and after checking out another viewpoint behind the parking lot, walked back a short way along the road so that I could skip the steep slippery section just below the summit; traffic was light, and I was rewarded with extra views through the trees. Half an hour later, I was back at the clearing passed on the way up.

After enjoying the view again, slightly different in the afternoon light, I continued down through the forest. Shortly before Atago shrine, I took an alternative path on the right, ending at a small lane on the north side of the mountain. At 3h30 I was back at the trail entrance; since I had about 30 minutes before the return bus, I paid a a quick visit to the nearby Daiyuji Temple and its statues with various interesting facial expressions. On the way back to the bus stop, I had one last view of Mt Takahara from Yakumo shrine.

This was another short hike, under 4 hours, but the superb views from half way up and the summit made it entirely worthwhile. It might be interesting to return one day by car to explore the area some more.
