The Mo Marimo

At The Marimo Observation Center:
The Center's Aquarium


The main exhibition aquarium hosts spherical marimo, other water plants, and two varieties of fish native to Hokkaido called himemasu and oshorokoma. This environment replicates the marimo's habitat in Lake Akan when the lake's water was beautifully clear.

A group of smaller aquariums feature the marimo's different stages of life beginning with spore formation, continuing on to its globular or round stage, and finally ending in a display of marimo in their disintegrating form.
