It was one of my fondest memory of my first travel in Japan, we had no clue that such site was there, so when we took the bus from whatever train station to the onsen hotel, and we passed in front of it, as a French, it was jaw dropping to see such place. Even crazier was when we actually visited it, they really captured my home region. Unbelievable experience.

Oh, it closed? That's too bad! We visited it when we were in Hakone in 2017—it was a remarkable experience finding it in Japan!
