A century-old inn with a garden bath
Tatsumikan is an inn of more than a century at Asamushi Onsen. Its bath faces a garden with a falling stream, so the mood of the seasons can be felt. At 500 yen it keeps a source-flow bath, offering good water without burden.
20 minutes by train from Aomori
Asamushi Onsen is a seaside spa about 20 minutes from Aomori by the Aoimori Railway. It is a few minutes on foot from the station, so a train visit is easy, with sea views across Mutsu Bay. The spa street has free foot baths, good for a walk before or after bathing.

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.
