Mt. Io, Teshikaga-cho

Witness the natural spectacle of sulfur vents at Mt. Io, an active volcano releasing sulfuric gases that often cause the surrounding landscape to turn yellow. A short 2.5 km (1.55 mi) scenic walk from the nearby town or from the onsite parking lot brings you right to the steaming vents and the rocky, barren landscape. The parking lot's fee includes access to the Lake Mashu caldera viewpoint. Plan a Teshikaga-cho trip in moments using our itinerary builder.

  • Smells very very strongly of sulphur. Interesting rocks and steam comes up from it. Go very early in the morning for free parking :)  more »
