Aidomari Onsen

Aidomari Onsen sits at the end of the road on the eastern side of the Shiretoko Peninsula, in the Aidomari hamlet of Rausu. Access is seasonal and dependent on local conditions. Like other Rausu-area wild baths, it is unstaffed and free. Visitors planning the drive should check current accessibility before setting out — the peninsula's eastern road closes through winter, and conditions vary with weather and the sea.
