Wakihama, Obama Onsen, Unzen, Nagasaki
Wakihama Onsen Bath (Otasshan-yu)
A compact, traditional public bath in a 1937 wooden building, best suited to a quick local-style soak. The regular opening time is listed as 6:00, but some 2026 sources still say 5:00; call ahead if you are planning an especially early visit. Water can run hot, and the facility has not published a current pool-treatment breakdown.

Check before bathing
- Opening hours
- Usually 06:00–21:00, with irregular closing days. Some 2026 sources list 05:00–21:00; confirm the earlier opening directly. Adult admission ¥400; children aged 3 through elementary school ¥200.

Spring & water temperature
- Spring-source temperature
- No current facility-specific figure is published. Older material cites about 90°C, while 105°C is a regional Obama Onsen figure; neither is a current bath temperature.
- Bathing temperature
- Not published; reports indicate it can vary with the day's water supply and adjustment.
- Spring source
- Obama Onsen; the individual source name is not published.
- Spring classification
- Sodium-chloride spring.
- pH
- Not published.
- Flow rate
- Not published.
- Water handling
- The current facility page does not specify dilution, heating, circulation or disinfection. An older tourism feature described a small flow-through supply after cleaning, but that should not be treated as a confirmed 2026 setup.
The water may feel very hot. Pour some over yourself first and test the temperature briefly.
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.
