Located near Kawayu Onsen in Akan-Mashu National Park, Iozan (Mount Io) offers a raw, dramatic encounter with Earth's volcanic power. Visitors can wander directly up to the mountain's smoking, bright-yellow vents to hear the roar of escaping subterranean steam. Don't miss sampling onsen eggs cooked directly by the natural volcanic heat, a beloved local snack sold on-site. The nearby Iozan Visitor Center provides a comfortable spot to pick up refreshments and learn more about the surrounding geothermal landscape.
