Akan is an area of volcanic craters and forests, covering 90 481 hectares (904.81 km2) .The park is famous for its crystal clear lakes, its thermal springs, and its large marimos. It is the only place in Japan where the marimo of an appreciable size is formed.


The park can be divided into two general areas, Kawayu and Akan.

Mount Iō and Onsen Kawayu offer natural hot springs and sulfur fumaroles. Around Lake Kussharo, a crater lake, are the Bihoro Pass, Mount Mokoto and Mount Nishibetsu. In the lake, the Wakoto Peninsula is an area with uniquely adapted soil and high temperatures, and Mashū Lake is a crater lake, one of the clearest lakes in the world, with visibility up to 40 meters.

The Akan caldera is a large volcanic caldera more than 20 km in diameter. Emerging from the interior of the caldera is the Akan Volcanic Complex, which includes the highest mountain in the park, Mount Meakan.The lake also has boiling mud, called bokke.
