Akiu Onsen, Sendai, Miyagi
Hotel Hananoyu Day-Use Onsen
A day-use hotel bath with indoor and riverside outdoor pools, plus a separately booked private outdoor bath. It closes to day visitors on Tuesdays and Fridays unless the day is a public holiday; the current day-use section takes precedence over older duplicated text elsewhere on the spa page.
Check before bathing
- Opening hours
- 10:30–14:00; last admission 13:00. Adult admission ¥1,200. Closed Tuesdays and Fridays, but open if either day is a public holiday. A private outdoor bath requires advance reservation and costs ¥2,500 per hour on weekdays or ¥3,000 on weekends and public holidays, plus day-use admission per person.
Spring & water temperature
- Spring-source temperature
- Not published in the current main pages.
- Bathing temperature
- No fixed temperature published.
- Spring source
- Hananoyu private spring.
- Spring classification
- Sodium-calcium chloride spring.
- pH
- Not published.
- Flow rate
- About 130 L/min for the private source; this is source yield, not flow into an individual bath.
- Water handling
- The hotel identifies its own natural spring. The private outdoor bath and open-air baths attached to guest rooms are explicitly source-flowing; treatment details for the regular day-use indoor and riverside baths are not fully published.
The ordinary day-use pools should not be described as source-flowing based on the separate private-bath statement.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
