From a brief historical information plaque, Houraijisan was a mountain some guy went to train for many many years. He lived to about 350 years old, and cured some important people, and a temple and nomenclature assigned to the mountain. My memory is bad but that's the gist of it.
At the top of about innumerable steps, there is a temple and a fantastic view of the valley. While it is winter, I can only imagine what it would be like with an Autumn explosion of red and orange hues.
Enjoy
Statues all over the place representing spirits i think
Entry to the mountain climb
Went to a shop where they make the stones used in the delicate art of mixing the black powder for calligraphy. Such a subtle art there are so many subtleties that affect how black ink on paper behaves.
At the end we went to a free hot spring footbath in a park. After a long walk it felt amazing!
