Bokke Mud Volcano
ボッケ
A mud volcano at the end of a forest trail on the shore of Lake Akan. Grey mud bubbles constantly, showing the active volcanic activity of the Akan area.
Bokke means boiling place in the Ainu language. It is a mud volcano on the eastern shore of Lake Akan, where volcanic gases rising from underground keep the mud bubbling and churning, with a sulfur smell. In winter, it steams amid the snow. From the Akan Lake Ecomuseum Center in Akan Lake Onsen, it takes about 15 minutes on foot along the lakeside forest trail, where you can also see Lake Akan and Mount Oakan. It is free. Note that the mud is very hot, so never climb over the fences. In winter, non-slip shoes are needed for the snowy trail.
