This hot spring is located along the rocky stretch of coast on the eastern side of the Shiretoko Peninsula in Hokkaido.

It is a completely natural spring and there are no hotels or buildings near by. It is encircled only by rocks. Because it isso near to the sea, it disappears at high tide.

The local shopowner of ‘Rausu kelp’ maintains the hot spring, so when you bathe, you should ask him first; this is the manner for this hot spring.

Before bathing, you should leave asmall tip in the wooden box, ‘the box of feeling’, toshow your respect and appreciation for him.

Bubbles from the source of the spring rise up under your feet. This  is just the ‘healing source’.
As you see the sea before your eyes, you can have thegreatness of nature all to yourself: there could be no more luxurious hot-spring trip.

By the way, the business hours and days are ‘low tide’ from June to September.
