Tokachi-Mitsumata Caldera

Tokachi-Mitsumata Caldera is a large volcanic basin in the Ishikari Mountains within Daisetsuzan National Park. Its steep walls and varied geological formations shape this mountainous landscape prominently.

The caldera formed through major volcanic eruptions thousands of years ago. These geological events left a landscape that still shapes Hokkaido's character today.

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

Well-marked trails lead to various viewpoints around the caldera. The best time to visit spans from spring through fall when paths are accessible and weather conditions remain stable.

Active fumaroles pierce the ground and continuously release steam and gases. These visible geothermal signs show that volcanic activity still persists beneath this landscape.
