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. Big windows frame Yunoshima island and the bay — sunset is the prime slot. Salt- and sulfate-rich water keeps you warm afterwards. Just ¥360, open 7:00–21:00 every day. 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.
Koganezaki Furōfushi Onsen
The highlight of any Gonō Line journey: a lone inn famous nationwide for its 'seaside open-air bath' set right at the water's edge of the Sea of Japan. Iron-rich chloride water, rust-red and cloudy, seems to merge with sea and sky. Day use is ¥600 — the seaside bath 8:00–16:00 (last entry 15:30), the main-building indoor 'Kogane-no-yu' 8:00–20:00. The mixed outdoor bath allows bathing wear (rental fee); a women-only outdoor bath sits alongside. Sunset soaks are for overnight guests only, so stay if you want one of Japan's 100 best sunsets from the tub.
