Ushitate, Aomori City, Aomori
Asunaro Onsen
A flexible choice in Aomori for early bathing, family baths and a women-only stone sauna. It suits families, couples and drivers better than a visitor relying only on a station-side walk. The current first-party tattoo policy has not been confirmed, so ask before entering.
Check before bathing
- Opening hours
- Main bath 05:00–24:00. Women's stone sauna 09:00–23:00. Family baths operate 24 hours, but reception stops 03:00–05:00; the facility is closed to entry during that period for public-bath cleaning. Rooms 1–16 are ¥1,800 per hour; two special rooms are ¥2,400 per hour. Current large-bath admission from June 1, 2026: adults ¥530, elementary-age children ¥200 and younger children ¥100.
- Tattoo policy
- No formal current tattoo policy was confirmed on first-party pages. Do not treat third-party reports as permission; confirm directly with the facility.

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.
