Nyuto Onsen Ogama Onsen
乳頭温泉郷 大釜温泉
One of the lodges of the Nyuto Onsen village in Semboku, Akita, uniquely housed in a relocated wooden school building. Hallways and stairs from its school days remain inside, giving it a nostalgic air beloved by secret-onsen fans. The green-tinged water - an acidic, bitter-tasting spring known as the wound bath and skin bath - flows free from the source, and there is an open-air bath usable even in winter. Beside the entrance stands the only footbath in Nyuto (roughly April to October). Day bathing runs 9:00-16:30 at 600 yen for adults (300 yen under junior high), and the Nyuto bath-hopping booklet is accepted. About 45-50 minutes by the Ugo Kotsu Nyuto-line bus from JR Tazawako Station, one minute from the Nyuto Onsen stop - a perfect base for touring all seven baths alongside Tsurunoyu, Kuroyu and Magoroku. Note that lodging is currently suspended; only day bathing is available.

More in this area

Tsurunoyu Onsen
The oldest inn in the Nyuto Onsen area, a hidden hot spring dating to the Edo period. The thatched 'Honjin' building and the large milky-white mixed rotenburo are its iconic scene. Day bathing 10:00–15:00; on Mondays the rotenburo is closed for cleaning and only indoor baths are open. Rooms sell out months ahead. From Tazawako Station take the bus, then the inn shuttle from Alpa Komakusa.

Kuroyu Onsen (Nyūtō)
The innermost of Nyūtō's seven baths — a cluster of thatched bath huts. Two separate sources feed a mixed open-air pool and gender-separated indoor/outdoor baths of milky sulfur water. Day use 9 am–4 pm, the longest window of the seven; closed mid-November to mid-April.

Nyūtō Onsen Tae-no-yu
The most polished of the seven Nyūtō inns, beside the Sendatsu stream and popular with women. Two sources — rusty 'gold' and clear 'silver' — in open-air baths above the rushing river. Day-use reception is short (10:30 am–2 pm), so come early.
