Fukenoyu Onsen (m) is a rustic hot spring in Akita Prefecture, just a few kilometers below the summit of Mount Hachimantai in Towada-Hachimantai National Park. Like nearby Goshogake Onsen, the slopes around Fukenoyu feature an interesting volcanic hot spring field where onsen waters bubble up directly out of the ground. These acidic waters are thick with mineral deposits (yunohana) and are said to be effective against neuralgia, infertility, gastrointestinal disorders, skin disease and fatigue among other ailments.

Fukenoyu features just a single, rustic ryokan that opens up its bathing facilities to non-staying guests during the daytime for 600 yen. While the baths inside the ryokan are fairly regular, the real treat at Fukenoyu are its outdoor baths (rotenburo) that were built in the midst of the hot spring field. The facilities include gender separated pools and a geothermal sauna. Note that while shielded from the trail, some of the pools are quite visible from the (distant) parking lot above. Fukenoyu is closed in winter (mid November to mid April).
