Iwate · Matsukawa Onsen, Hachimantai
Matsukawa Onsen Kyōunsō
松川温泉 峡雲荘
A lone inn of the Japan Association of Secluded Hot Springs, deep in Hachimantai National Park amid beech and oak forest. The open-air bath is an unusual greenish milky white — free-flowing simple hydrogen-sulphide water — with a mixed outdoor bath, a women-only outdoor bath and separate indoor baths; from the rotenburo you can see the steam of Japan's first geothermal power station. Day use 08:30–19:00 (last entry 18:00), ¥700 for adults, or ¥900 with hall rest 10:00–15:00. Open year-round, and the snow-buried outdoor bath in winter is the highlight. About 1 h 50 min by Iwate Kenpoku bus from Morioka Station to the Matsukawa Onsen terminus.

Osawa Onsen Jisuibu Tojiya
A wooden toji (therapeutic stay) inn over 200 years old on the Toyosawa River in the Hanamaki-Minami onsen area, once frequented by poet Kenji Miyazawa. Its signature is 'Osawa-no-yu', a mixed open-air bath jutting over the river, with women-only hours. Day bathing from 7 am; ¥700 covers three baths. Many linger for lunch and sake at the 'Yahagi' dining room. Free shuttle from Hanamaki Station.
Namari Onsen Fujisan Ryokan
A wooden ryokan founded in 1841 on the Toyosawa River at the far end of the Hanamaki onsen villages. Its signature is 'Hakuen-no-yu', a self-welling rock pool about 1.25 m deep that you stand in — billed as Japan's deepest rock bath. Five springs feed four bathhouses, all 100% free-flowing. Day use ¥800, 10:00–21:00. Hakuen-no-yu is mixed bathing with women-only hours. Free shuttle from Hanamaki Station by reservation.
Oshuku Onsen Hotel Uguisu
Fifty minutes by bus from Morioka, a family-run hotel in Oshuku Onsen, a 450-year-old spa where legend says a bush warbler healed its wounds. The area is rich in hot water, and the clear alkaline spring flows freely into the indoor and open-air baths — day use just ¥600, 11:00–19:00, half price on the 26th of each month. Easy to add after Koiwai Farm, Shizukuishi ski slopes or Morioka sightseeing.
