Things to do
Rishiri and Rebun

A one-day climb to the summit (1,721 m): via Oshidomari, from the Hokuroku campsite, allow about 11 hours return; the Kutsugata trail is shorter but rockier. Take a portable toilet kit (¥400) and file a route plan before setting off.

Seven marked trails criss-cross the island, including the 8-hour trail along the west coast from north to south, which can also be done in two 4-hour sections. The capes walk links Cape Sukoton with Hamanaka via Gorota and Sukai, about 12 km in 5 h 40.

Guides specialising in Rebun’s alpine flowers, for group or private hikes: Momoiwa viewpoint, Momoiwa–Shiretoko, the Rebun forest road, the Edoya trail and the capes walk. They lead visitors from May to September, following the blooms.
