Atami Onsen, Atami, Shizuoka Prefecture
Hotel New Akao (Day-Use Onsen)
A good fit if you want sea views and a chance to compare three springs in one visit. Allow at least a couple of hours; a very short stop makes less use of the day ticket.
Check before bathing
- Opening hours
- Day use normally 13:00–18:00; last entry 17:00. The three baths open at different times: Namine from 13:00, Sparium Nishiki from 14:00 and Saikai from 15:00.
Spring & water temperature

- Spring source
- Atami No. 402 (Nishikiura), No. 196 and No. 353 (Nishikiyu) springs.
- Spring classification
- All three are sodium-calcium chloride springs; the facility's published wording varies slightly in the order of the minerals.
- pH
- No. 402: pH 7.3; No. 196: pH 7.31; No. 353: pH 7.9.

- Water handling
- The hotel identifies which spring is used by each bath: Atami No. 402 at Sparium Nishiki, No. 196 at Saikai and No. 353 at Namine. The current official pages do not fully publish water addition, heating, circulation or disinfection conditions pool by pool, so the whole property is not described as source-flowing.
Bathing indications
The hotel lists general bathing indications for each spring. This profile does not promise treatment effects.

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.
