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.

  • It is located between Lake Mashu and Lake Kussharo. The mountain itself is just off the train. Sneakers are recommended because the foot is bad when going to the outlet of sulfur. You can touch the hot springs springing up, but it is quite hot depending on the location.

  • When I paid the parking fee at Lake Mashu's first observatory, the parking ticket here came with a set. At first, I didn't want to come here, but I tried to waste my ticket. Personally, i wish I had time, but if I didn't have time, I could go through.
