Iwate · Matsukawa Onsen, Hachimantai
Tōshichi Onsen Saiunsō, Hachimantai (1,400 m)
藤七温泉 彩雲荘（八幡平・標高1,400m）
The highest hot-spring inn in Tōhoku, at 1,400 m near the top of the Hachimantai Aspite Line. It opens only from Golden Week to late October; in winter it is buried in snow. Five mixed open-air baths scattered down the slope (plus a women-only open-air bath and separate indoor baths) are fed by sulphur water bubbling up directly through the ground, milky white, and the trademark is smearing the mud from the bottom on your skin as a 'mud pack'. Below spread Mt Iwate and a sea of forest; at dawn, cloud seas and sunrise — truly a bath above the clouds. Simple sulphur water at temperatures from tepid to hot. Day bathing: adults ¥650, children ¥350, with a long 08:00–18:00 window, busy with hikers back from the Hachimantai summit trail. The open-air baths are mixed, so bathing garments and wrap towels are allowed. About 2 hours by bus from Morioka Station or 40 minutes by car from Matsuo-Hachimantai IC. Mobile reception is poor.

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.

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.
