380. Nakamura Hot Spring, Minamata, Kumamoto Paid 500 yen to the grandmother at the shop (the location is marked on the screenshot), then she took me to a separate building with the onsen. Operating hours listed as 10:00 to 22:00. They stamp the 88 Onsen of Kyushu book. As I understood, the bath is private since the grandmother told me to lock the door. The changing room has equipment for visiting the onsen with a child, plus some interesting artifacts. Bath with clear water, temperature around 42. Breathing is excellent.
