Tsurunoyu Onsen

History and setting

The oldest of the seven Nyūtō springs: records show the Akita lord Satake Yoshitaka coming to take the waters in the Kan'ei era (1624–44), and an inn was operating here by 1661. The name comes from a legend of a hunter who saw a wounded crane (tsuru) healing itself in the spring. The thatched long-house 'Honjin', once quarters for the lord's guards, is still used as guest rooms with sunken hearths. Bath huts are scattered along a stream in primeval beech forest, and in winter the sight of thatched roofs under two or three metres of snow beside the milky open-air pool has become the defining image of a Japanese 'hidden hot spring'. A member of the Japan Association of Secluded Hot Springs, it is often booked out months ahead for overnight stays, but day bathing is accepted 10:00–15:00 and includes almost every bath, the big mixed rotenburo among them.

How to bathe here & practical notes

• The baths are in several separate huts, each indoor bath (Shiro-yu, Kuro-yu, Naka-no-yu) with its own changing room — women change three times and men twice to try them all, so allow plenty of time.
• No bathing garments, swimwear or wrapped towels in the mixed rotenburo. Women can, however, slip in directly from the Naka-no-yu bathhouse along the rocks, and the milky water hides the body, making it manageable even for first-timers. If mixed bathing is not for you, use the women-only rotenburo.
• Washing facilities are rudimentary with almost no showers; no soap, shampoo or hair dryers. Bring a towel (also sold).
• In the rotenburo the water rises through the gravel floor, so the temperature varies — hot near the source, cooler at the edges.
• Sulphur tarnishes silver and the smell lingers after bathing. Take breaks; long soaks bring on light-headedness.
• No explicit tattoo ban is posted (be discreet, as is customary at secluded inns).
• Cash only, and mobile phones often have no signal. From late November to April the road is icy and snowbound — winter tyres are essential, or take the shuttle bus.
• Day bathing is 10:00–15:00 only; no entry after check-in time or in the morning. In autumn-leaf season and on winter weekends it is busiest around midday, so aim for the 10 am opening.

Access and touring the Nyūtō springs

From Tazawako Station (Akita Shinkansen) take the Ugo Kōtsū Nyūtō-line bus about 35 minutes to Alpa Komakusa, then change to Tsurunoyu's own shuttle for the final 10 minutes (day visitors welcome; call ahead). From the 'Tsurunoyu Onsen Iriguchi' stop it is a 3 km unpaved walk of about 35 minutes — not realistic in winter. By car it is about 40 minutes from Tazawako Station or 1.5 hours from Morioka IC; parking is free. The Nyūtō group comprises seven inns — Tsurunoyu, Taenoyu, Kuroyu, Ganiba, Magoroku, Ōgama and Kyūkamura — and overnight guests can buy a 'Yumeguri-chō' pass (¥2,500, valid one year) covering all of them. On a day trip the classic pairing is Tsurunoyu plus Kuroyu (10:00–16:00, closed in winter) or Taenoyu (10:00–15:00, closed Tuesdays).
