Dogo Onsen is one of the oldest hot springs in Japan, with a long history of 3,000 years. The main building of the hot spring bath is a three-story wooden structure. After it was built, it became the symbol of Dogo Onsen. The bath in the animated film "Spirited Away" was created based on this. In 1994, Dogo Onsen was designated as an important cultural heritage by the Japanese government for the first time as a hot spring facility. This building has a magnificent and retro appearance, which is a perfect fusion of classic and modern. The hot spring hall has three floors, and different floors correspond to different prices. In addition, you can pay to visit the royal bath. There are two bathrooms on the first floor, Rei no Yu and Kami no Yu. The second floor and above are rest rooms. The young master in the novel likes to use the separate room on the third floor of Rei no Yu. There are photos of Natsume Soseki inside, which can be visited for free
