About
Imogawa Onsen (いもがわ温泉) is a small public bath inside the Asahi town senior activity centre. It is a plain setup: an indoor bath and a washing area, and reviewers describe it as a community hall where locals drop in. The building also has a dining hall with a wide menu that includes seafood, which is a pleasant surprise this far in the hills, and there is parking.
