Nyuto Onsen Magoroku Onsen (Rokuan)
乳頭温泉郷 孫六温泉(孫六温泉 六庵)
One of the seven baths of the Nyuto Onsen village in Semboku, Akita, a secret spa known as the mountain's medicinal bath. After closing for renovation from 2023, it was reborn as Magoroku Onsen Rokuan, resuming day bathing in February 2025 and lodging that April. Lodging and bath houses stand apart in a rustic layout; of its four sources, the indoor Ishi-no-Yu and Karako-no-Yu are waku-to baths where water wells up through the tub floor. A simple sulfur spring (Ishi-no-Yu, 51.6°C) and a simple spring (Karako-no-Yu, 49.9°C) flow free - faintly green clear water and milky-white water alike. Besides separate indoor and open-air baths there are mixed-bathing indoor, open-air and sauna baths (said to be among Nyuto's easier mixed baths). Day bathing runs roughly 10:00-15:00 in two tiers: 700 yen for the indoor baths only, 3,000 yen for all baths. A bath-hopping booklet covering Tsurunoyu and Kuroyu can also be used.

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.
