The Hiba Sennin-buro is a pillarless 160-tatami cypress hall holding four separate acidic sulphur sources, which is about as strong a spring-quality case as exists in Tohoku; what you look at from the water is the timber roof rather than any landscape. A lone inn at 900 m in the Hakkoda mountains reached by a year-round JR bus from Aomori, with a self-catering cure wing and a restaurant, and nothing outside but the Hakkoda trailheads.

The baths

Indoor bath

The Hiba Sennin-buro ('thousand-person bath') is a 160-tatami hall built entirely of hiba cypress with no supporting pillars, holding four different source waters (Netsu-no-yu, Hie-no-yu, Shibu-roku-bu-no-yu and a hot waterfall). It is mixed bathing. Women-only hours are 8:00-9:00, and the ryokan's FAQ states this applies both morning and evening. Bathing wear is optional but must be bought (women's, 1,300 yen) or rented (unisex, 500 yen from the shop, 7:00-20:00) on site - you may not bring your own.

Open to day visitors

Indoor bath

Tama-no-yu is the smaller bath and is permanently split by gender, so it is the option if you do not want mixed bathing at all. Different source from the big hall but the same acidic sulphur water.

Open to day visitors

Getting there
A single inn deep in the Hakkoda mountains about 30 km south of Aomori city at 900 m altitude, on National Route 103. JR buses run year-round: roughly 70 minutes from Aomori Station east exit, 80 minutes from Shin-Aomori Station, 90 minutes from Lake Towada (Yasumiya). Staying guests can reserve a free shuttle from Shin-Aomori Station (10:15 and 14:00 outbound). Winter is severe - snow depth exceeds 5 m, several Hakkoda roads shut overnight from mid-December to mid-March and the Kasamatsu Pass towards Oirase is fully closed from mid-December to 31 March, so plan to arrive before 17:00 and use winter tyres or chains.
