Mount Sashirui

サシルイ岳

Rausu, Hokkaido · Elevation 1,564 m

Mt. Sashiruidake is a 1,564-meter twin-summit peak on the boundary between Shari Town in Shari District and Rausu Town in Menashi District, Hokkaido, lying along the main ridge of the Shiretoko Range between Mt. Rausu and Mt. Iō. It is one of the peaks on the Mt. Rausu–Mt. Iō traverse, alongside Mitsumine and Okkabake, although the maintained trail skirts its western flank so reaching the actual summit requires a brief off-trail detour. Within Shiretoko National Park, the alpine slopes display extensive summer wildflower fields including Geum pentapetalum and the endemic Shiretoko violet. Permafrost was confirmed near the summit in 2024.
