The Legend of Marimos

The Legend of the Marimo – Lake Akan, Hokkaido 🌿 🇯🇵 Deep in the cold, clear waters of Lake Akan, a mysterious green sphere slowly rolls with the movement of the waves. The Ainu people tell a legend of two lovers, Senato and Manibe, whose love was forbidden. Rather than live apart, they disappeared into the lake — and their spirits are said to have become Marimo, the soft green algae balls that still live there today. Because of this story, Marimo are seen as symbols of eternal love, loyalty, and good fortune. 🎉 The next Lake Akan Marimo Festival is expected to be held from October 8–10, 2026. During the festival, Ainu ceremonies, torchlight processions, dances, and the ritual return of Marimo to the lake honor both nature and tradition. 🟢 What makes Lake Akan Marimo so special? They are among the world’s most famous naturally round Marimo, known for their rare spherical shape, slow growth, and impressive size — a living treasure of Hokkaido.
