Hakkoda Jogakura Onsen HOTEL Jogakura
八甲田城ヶ倉温泉 ホテル城ヶ倉（HOTEL Jogakura）
A resort hotel standing at Jogakura Onsen, opened in 1965. It lies only two kilometres from Sukayu Onsen, known for its acidic sulphur spring, yet here a clear and mild water rises, said to be easy on the body and suitable even for sensitive skin. Day bathing is received from 11:30 to 15:00, last entry 14:30, at 1,000 yen for adults, 500 yen for elementary pupils and 300 yen for infants. The open-air bath runs straight from the source and, unusually for Hakkoda, can be used all year. The main bath has a cold bath, a mist sauna and a whirlpool, while the indoor bath is adjusted with added water, heating and circulation. Hand towels are sold for 200 yen and bath towels are not lent out.

Why go
- An open-air source bath that can be used all year
- Clear, mild water
- A main bath with a cold bath and mist sauna
Two kilometres from Sukayu, with quite different water
In the Hakkoda mountains lies Sukayu Onsen, known for its acidic sulphur spring. This inn stands only two kilometres away, yet its water is a colourless, clear calcium-sodium chloride spring. It is easier to enter for those who find acidic water hard on the body, and since long ago it has drawn visitors with sensitive skin. The two spas sit on the same JR bus route, so both can be covered in one day.
An open-air bath usable all year in Hakkoda
In snowy Hakkoda, quite a few places close their open-air baths in winter. The one here stays open all year, and you can bathe looking at a virgin beech forest under snow. The tub is shaped for lying in the water, which is easier on the body, and with a cold bath and mist sauna in the main bath, alternating hot and cold is possible. Day bathing runs only from 11:30 to 15:00, so it is best to time the visit.
Before you go
- No official tattoo policy is published — ask at reception.
- Ryokan day-use hours are limited and may be suspended in peak season — phone the same morning.

Sukayu Onsen Hiba Sennin-buro
In the Hakkoda mountains, bathing since 1684 and Japan's first National Recuperation Onsen. A vast all-cypress mixed bath hall (about 260 m²) fed by four sources. Women-only hour 8–9 am daily; bathing garments sold on site.
Yu-sa Asamushi Roadside Station — Hadaka-yu Panoramic Bath
Twenty minutes by train from Aomori, a panoramic bath on the 5th floor of the roadside station at Asamushi Onsen on Mutsu Bay.

The ground-floor market sells Aomori souvenirs. Two minutes' walk from Asamushi-Onsen Station.
Tsuta Onsen Ryokan
A lone inn in a primeval beech forest on the southern flank of Mt. Hakkoda. Spring water wells up directly through the gaps in the hiba-cypress boards on the tub floor — 'free-welling', so you bathe in water that has never touched air, a rarity even in Japan. The all-hiba 'Kyuan-no-yu' bathhouse from 1918 is magnificent. Day use 10:00–15:00, ¥1,000; may close early when busy. Combine with the hour-long trail around Tsuta-numa pond, famous for autumn colour. Closed in winter.
