○Somewhere to sit — You can spend the day here

×Anything else nearby — Nothing else around

A strongly saline natural spring drawn from 2,000m down, inside a 24-hour leisure complex where you can eat, sleep in a reclining seat and stay all night. No open-air bath is documented and the site is a bayside entertainment block by the expressway, so there is nothing to look at from the water.

Scored from official photos, maps and transport information — not from a visit.

The baths

Indoor bath

Genuine natural hot spring: the operator states the water rises from 2,000m below ground at about 150 tonnes a day and is high in salt, which they describe as among the best in Tokyo. A formal spring-quality name is not published.

Open to day visitors
