At "Marimo Exhibition Observation Center" on Cheului Island in Lake Akan, during the winter when the facility is closed and the surface of the lake freezes, Marimo, which is exhibited in the aquarium, is being returned to the lake.

Sales of our facility finished on the 30th last month and on the 3rd, employees of the company managing the facility took out the last seven of the marimos displayed from the aquarium to the pier.

And putting the rope inside the tightened basket, it was submerged in a lake about 4 meters deep. There are 111 marimos returned to the lake, which are to be exhibited again after being passed through the year under the frozen water surface and raised in April next year.

Yushiichi Oyama, curator of the Kushiro City Board of Education, Yoshikazu Oyama says, "Because it is low temperature in the winter, it does not grow, but it is kept in the same condition until the spring in the lake. I want you to come. "
