About Lake Akan | A Mystical Volcanic Lake in Eastern Hokkaido
Lake Akan is a caldera lake located at the center of the Akan Mashu National Park with a circumference of approximately 26km and a maximum depth of 44.8m. Formed by the eruption of Mt. Akan-Dake approximately 6,000 years ago, it has a geological history where the formerly unified ancient Lake Akan divided into three separate lakes: the current Lake Akan, Lake Panketo, and Lake Penketo.
The Lake Akan hot spring town spreading along the southern shore of the lake is Hokkaido’s leading hot spring resort visited by approximately one million people annually. Its location surrounded by Mt. Meakan-Dake (elevation 1,499m) and Mt. Akan-Dake (elevation 1,371m) creates a fantastic landscape with the reflection of the surrounding mountains on the lake’s surface.

The Special Natural Monument “Marimo” of Lake Akan | Mystery Revealed
What has made Lake Akan famous worldwide is the “Marimo of Lake Akan,” designated as a special natural monument of Japan. Marimo is a type of freshwater green alga, and the marimo inhabiting Lake Akan is known for forming beautiful spherical bodies.
Ecology and Characteristics of Marimo
Marimo (ball-shaped algae) is a rare organism formed when thread-like algae become intertwined into a spherical shape. What makes Lake Akan’s marimo special is that large spherical marimo reaching 20-30cm in diameter form colonies—the only place in the world where colonies of this scale exist.
The growth rate of marimo is extremely slow; it takes approximately five years to reach 1cm in diameter, and larger specimens are thought to take 150 years or more to grow. These perfectly spherical forms develop only in specific locations with particular conditions (water flow, light intensity, water quality).
Facilities Where Marimo Can Be Observed
The actual marimo colony sites on the lake floor are off-limits for protection, but natural marimo can be observed at the following facilities.
Chuurui Island Marimo Exhibition and Observation Center
Located on Chuurui Island, approximately 15 minutes by sightseeing boat, this facility features a large aquarium recreating the lake floor of Lake Akan where you can observe the ecology of natural marimo up close. The sight of marimo thriving at a depth of approximately 2m is spectacular.
Lake Akan Shore Eco-Museum Center
Located in the hot spring town, this facility offers learning opportunities about marimo ecology and the natural environment of Lake Akan. The marimo specimens on display and video materials are ideal for deepening understanding of marimo.
