This is a river cleanup event aimed at preserving the natural environment of the pristine Shiribetsu River. Please bring your own work gloves, towels, and tongs.

The cleanup will be divided into two groups: one for cleanup by canoe and raft, and another for cleanup on land. Since the canoe and raft cleanup is very popular, please apply as soon as possible.

This initiative was selected for the Excellence Award in the 2024 “Kawatabi Hokkaido Grand Prix.”
