I cannot say that it was a mountain climbing but you can say that it was a hill hiking. Because, the mountain was equipped very long steps from the parking lot to the top of the Komaru-yama, or Mt. Komaru.
You can easily go up to the top of Komaru peak.
Here is the top of Mt. Komaru. This route goes to Mt. Akanagi, height of 2,010m.
My wife and I stayed in a hot spa resort, Kirifuri highland.
We wore Japanese traditional clothes, Yukata, had delicious dinner, took a walk near the forest.
Needless to say, we enjoyed hot spring while viewing stunning mountain scenery, sun set and sun rise.
