Seseki Onsen
瀬石温泉
A seaside rock bath that emerges from the sea only at low tide and sinks back underwater at high tide, known as the 'dream hot spring'.
Seseki Onsen is a seaside open-air bath enclosed by rocks, near the end of the road along Rausu's northern coast. At high tide it is submerged, so you can bathe only for a few hours around low tide, and you should check the tide tables in advance. The hot spring is on private land, and the owner has kindly opened it to the public. It is free, has no changing facilities, and is often visited as a sightseeing stop. About 2 km further north, the road's end also has Aidomari Onsen, which is open in summer and has simple screening. It is about 30 minutes by car from Rausu town. Please observe etiquette and take your trash with you.
Opening hours
Approx. July–September, low tide only
