Mushroom ice" is a unique natural phenomenon found in Lake Nukabira, a dammed lake. Every winter around February, the water level drops to the bottom of the lake due to hydroelectric power generation, and the frozen lake surface remains on top of the stumps at the bottom of the lake. This is called "mushroom ice" because it looks like a mushroom.

More than 100 mushrooms of all sizes will appear

.
On this tour, you will walk about 1 km on the lake with snowshoes. On the way, you will also visit the Sanosawa Bridge. The tour will take you to a place on Lake Nukabira where the ice mushrooms are in disarray, which is different from the route across the Tausubetsu Bridge.
