I did this hike with my mother who was visiting Japan for a couple of weeks. Since it was quite far from Tokyo, we rented a car in Takasaki, and spent the night in a traditional Japanese inn, or “ryokan”, in Kusatsu Onsen. The next morning was sunny, but by the time we had made our way all the way up to Yugama Lake 湯釜 the clouds had rolled in. We admired the light blue colour of the crater lake, but gave up on climbing Mt Kusatsu-Shirane. I had climbed it before in the clouds, and had little interest in doing it again in similar conditions.

We drove on to Yokoteyama Ropeway which took us to the top of Mt Yokote 横手山. We got some nice views of Shiga Highland 志賀高原. Fortunately, the Nagano side was still free of clouds. We finally arrived at Kumanoyu (meaning the bear’s bath) where we left the car. We were now firmly inside Nagano prefecture. Another short ropeway took up to the start of the hike. Luckily, the weather was holding up. The first part was quite level. At one point the path went through some very high bamboo, higher than our heads, and I was worried about bears. So I reached into my bag to retrieve my bear bell only to realise that I had left it in the car!

Soon the path started to climb. It was steep, with big rocks and protruding tree roots, making progress slow. The path slowly wound up the side of the mountain. We saw few people, and thankfully no bears. We reached the top of Mt Shiga 志賀山 just before 2 pm. A little way past the summit, there were some good views of Onuma-ike Lake below. The whole hike is inside the Joshin Etsu Kogen National Park and is very wild and beautiful.

We climbed down via a different path, spotting various small ponds on the way. Finally, after passing through a shinto gate or “torii”, we reached the base of the cone-shaped Mt Shiga. The next part involved walking along an elevated walkway through marshlands – much easier than the rocky path down the mountain! The final part back to the ropeway was along a wide and level path through the forest.

Since it was getting late, we decided not to take a bath at Kumanoyu, and leave right away. No sooner had we set off, that a dark shadow dashed across the road – it was a bear cub. It disappeared into the bushes opposite. We waited a bit for a mother bear, but she was nowhere to be seen. In any case the place certainly deserves its name!

On the way back, we stopped briefly for some photos at the marker for the highest national road in Japan at 2172m high. The drive down to Kusatsu onsen was through thick mist. We had a bath at the Sainokawara open-air bath, one of the biggest in Japan. After we were done, it started raining really hard, but we managed to get back to Takasaki safe and sound, a little after nightfall.
