Atami Onsen, Atami, Shizuoka Prefecture
KKR Hotel Atami (Day-Use Onsen)
A convenient last stop for car-free travellers who want a sea-view bath before returning to Atami Station. Weekend, holiday, fireworks-day and cleaning-day closing times can differ, so confirm before going.
Check before bathing
- Opening hours
- The usual listing is 11:00–20:00 for day visitors, with cleaning days to confirm. On weekends, public holidays and fireworks days, bathing ends at 15:00.
- Tattoo policy
- Not permitted. The facility says guests with tattoos may not use the baths.
Spring & water temperature
- Spring-source temperature
- 64.3°C.
- Bathing temperature
- Not published.
- Spring source
- The hotel's own on-site spring.
- Spring classification
- Sodium-calcium chloride spring.
- pH
- The same official page lists both “P.H. 6.6” and hydrogen-ion concentration pH 7.1; both published values are retained rather than reconciled.
- Flow rate
- Not published.
- Water handling
- The hotel describes itself as an inn with source-flowing hot-spring water and uses its own on-site spring in the seventh-floor panoramic bath. The current page does not fully specify water addition, heating, circulation or disinfection for every pool, so no uniform treatment claim is made.
Bathing indications
The hotel lists general bathing indications. This is not a treatment guarantee.
Adult day admission is normally ¥1,800. The ¥2,000 summer rate applied only from 1–23 August 2026 and has ended. Cleaning days occur; check the schedule. Tattoos are not allowed in the baths.
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.
