Ajigaura Onsen Nozomi
A strong option for a high-salinity spring, a broad range of pools and easy access on foot from Ajigaura Station. Families can book one of five private baths that the operator identifies as 100% source-flowing. Tattoos are barred from the shared bath but allowed in a paid private family bath.

Spring & water temperature
- Spring-source temperature
- Not published.
- Bathing temperature
- The outdoor cypress bath is set to 43–44°C; this is a pool setting, not the source temperature.
- Spring source
- The facility's own spring, drawn from about 1,506 metres below the site.
- Spring classification
- Highly concentrated sodium-chloride spring.
- pH
- Not published.
- Flow rate
- Not published.
- Water handling
- The public bath uses natural hot spring water, but the current operator page does not document each pool's treatment. The operator specifically describes all five private family baths as 100% source-flowing; that claim applies to those private baths.
Children under three may not use the shared bath, but may use a paid private family bath.
