Nagareyama Otakanomori, Nagareyama, Chiba
Spa Metssa Otaka Ryusenji-no-Yu
Spa Metssa Otaka is worth a visit even if you skip the hourly Dragon Loyly: the three sauna styles, deep bath and natural-spring area give you other ways to shape the session. Go early if you want more room; the hourly event is only one part of a busy facility.

Spring & water temperature
- Spring-source temperature
- Not published
- Bathing temperature
- Not published as a fixed value. The 157 cm figure describes water depth, and a sub-10°C cold bath is a cold-bath setting, not spring temperature.
- Spring source
- A natural hot-spring source is confirmed at the facility; the current profile does not identify a source name
- Spring classification
- Natural hot-spring pools are present; a current property-specific analysis was not confirmed in readable text
- pH
- Not published
- Flow rate
- Not published
- Water handling
- The natural spring pools are separate from the facility's carbonated and functional baths. Current readable material does not establish complete treatment conditions for each pool.
Bathing indications
No spring-specific bathing indications are added without a current readable facility analysis.
Dragon Sauna's five HARVIA stoves run a synchronized Dragon Loyly at the top of each hour; ordinary 10-minute automatic loyly is a separate event. There are three distinct sauna concepts, a 157 cm deep-water bath and a natural-spring section. Tattoos require complete coverage with up to two designated 9.5 × 14.0 cm seals.
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.
