Yudaki Falls

The Yugawa River exits Lake Yunoko and drops seventy meters over Yudaki Falls, a wide cascade with an observation deck at the base for close views of the rushing water. Below the falls, the river continues south through Senjogahara, a vast marshland covering over 400 hectares, now protected under the Ramsar Convention. The name Senjogahara means battlefield plain, referencing a myth about a war between centipede and snake armies. Thousands of years ago this was a lake; volcanic debris gradually filled it in. A raised wooden boardwalk is the only permitted route through, keeping foot traffic from disturbing the wetland ecosystem.
