大島温泉 元町浜の湯おおしまおんせん もとまちはまのゆ
Shared bathing area for all genders
A bathing garment (yuami-gi, 湯浴み着) or swimsuit is required.
An open-air bath perched above the shore of Oshima Island, where you soak in swimwear with the ocean spread out in front of you, on a clear day you can see Mount Fuji across the water and the Izu Peninsula lit up at sunset. The spring emerged after the 1986 eruption of Mount Mihara, which gives this small public bath an unexpectedly dramatic origin story.

Motomachi Hama-no-Yu Mixed bathing onsen with swimsuits, 300 yen. Large pool, feels like 40-41. View of the sea, mountains, and Mt. Fuji. Mostly local elderly men and one elderly woman. Good like everything in Oshima, but out of the three, the upper one is my favorite, especially when it's hot.
