Osawa is a toji inn — a hot spring where people came to stay for weeks and cook for themselves, not for a night of kaiseki. The jisui-bu, the self-catering wing, is a rambling wooden building of dark corridors and shared kitchens that has been in continuous use for a very long time, and it is still run that way: you can take a room, buy food, and cook it.
The bath that draws people is Osawa-no-yu, a mixed open-air pool on the bank of the Toyosawa river directly under the wooden building, with nothing between it and the water. A day ticket at the jisui-bu reception costs ¥600 and covers that plus the indoor Yakushi-no-yu, the Toyosawa bath, the women-only Kawabe-no-yu and, from two to five in the afternoon, the Nanbu-no-yu at the Kikusuikan building.
