Tokachi-Mitsumata Caldera

The Tokachi-Mitsumata Caldera extends 8 kilometers across the Ishikari Mountains, featuring steep walls and multiple geological formations within its boundaries.

The formation of this massive caldera occurred through a series of volcanic events thousands of years ago, shaping the current landscape of Hokkaido.

Local communities have developed specific emergency preparedness practices and traditions due to their proximity to this volcanic formation.

Several maintained hiking trails provide access to observation points around the caldera, with guided tours available from April through October.

The caldera contains multiple geothermal features, including active fumaroles that release steam and gases through vents in the volcanic rocks.
