We were walking in the narrow streets of Shibu Onsen, a Japanese village in the mountains near Nagano. A lot of people going around after having thermal baths. We stopped in front of a big old hotel, with a few people taking pictures. We looked at the hotel, illuminated in the incoming night, and it was that bath house from Spirited Away anime (a famous 2001 Japanese animated fantasy film)!
Actually, in Japan it is recognized as the inspiration for Miyazaki, the director, to create the old witch bath house of the anime and you must visit it if you are a Miyazaki fan!
