216. Dormy Inn Morioka Sansa-no-yu A business hotel with an onsen, 14 minutes on foot from Morioka Station. Photos of baths from the internet match reality. 1. Indoor rectangular bath with clear water, temperature 40. 2. Sauna. 3. A tub with cold water inside. 4. Outdoor bath with clear water, temperature 40. Located on what's essentially a balcony, but everything is behind a fence. 5. Across from the main outdoor bath, a single-person tub. Water is clear, temperature 40. Breathing inside is comfortable. A perfectly decent onsen for a business hotel, especially given the shortage of onsens in Morioka. If the distance from the station doesn't bother you and you need an onsen, it's a solid option.
