Asamushi Onsen, Aomori City, Aomori Prefecture
Asamushi Onsen Public Bath Matsunoyu
A simple public bath for a low-key Asamushi visit, with a family-bath room available by reservation. Confirm availability and the final bill before travelling: official sources differ on children's prices and spring classification.
Check before bathing
- Opening hours
- Adults ¥360. Published child rates differ by source: ¥150 or ¥160; infant rates are listed as ¥60 or ¥70. A 60-minute family room is ¥1,400, with ¥700 for each additional 30 minutes. Whether the room fee is charged in addition to admission is unclear and should be confirmed. Closed Mondays and New Year's Day; family-bath bookings take priority.
- Tattoo policy
- The current sources reviewed do not confirm a tattoo rule; ask the bath before visiting if needed.
Spring & water temperature
- Spring-source temperature
- Not published.
- Bathing temperature
- Not published; the family bath is described as hot and adjustable with added water, without a fixed figure.
- Spring classification
- Aomori City tourism describes a simple spring; the prefectural tourism page gives a sodium-calcium sulfate-chloride classification for the family bath. No current individual analysis sheet was available to resolve the difference.
- pH
- Not published.
- Flow rate
- Not published.
- Water handling
- Aomori City tourism describes the general bath as 100% source-flowing, without added water or heating. The prefectural tourism page says water may be added to the family bath; do not extend the general-bath description to every pool. Circulation and disinfection details are not published.
The family room should be reserved in advance; arrival does not guarantee availability. Confirm guest limits, room-fee treatment, tattoo access, diaper rules and accessibility requirements with the bath.
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.
