- Baths that switch daily
An onsen on the shore of Lake Gosho
Tsunagi Onsen lies on the shore of Lake Gosho, close to Morioka. Aishinkan is a large onsen inn on that shore, where the garden open-air bath looks out over the lake and the mountains. The water is strongly alkaline and known for leaving the skin smooth. With the main bath open until early morning, it also suits the end of a day.
Prices and checking
Weekday and weekend rates differ, and on weekends and holidays it runs only until 15:00. Unlike other spas in Miyagi and Iwate, the main bath can be used late, so an evening visit still leaves time. It does close on some days, though, so a phone call is the safe course.
Before you go
- No official tattoo policy is published — ask at reception.
- Ryokan day-use hours are limited and may be suspended in peak season — phone the same morning.
- Last entry is 30–60 minutes before closing.
