Nikko Senjogahara Marshland

Elevated boardwalk through highland marshland with mountain views in Nikko.

Senjogahara is a vast highland marshland at 1,400 meters elevation in Nikko National Park, Tochigi Prefecture. The well-maintained boardwalk trail traverses the open wetland with views of volcanic peaks including Mt. Nantai. The area is renowned for its seasonal beauty—fresh green in spring, wildflowers in summer, golden grasses in autumn, and snow-covered silence in winter. It connects to several waterfalls including Ryuzu and Yutaki.
