Bihoro Pass, on Route 243 at the boundary between Bihoro and Teshikaga in Hokkaido, sits at 525 m elevation as the central viewpoint of Akan-Mashu National Park. Below lies the caldera lake Kussharo (57 km in circumference, Hokkaido's largest lake and Japan's largest caldera lake), with Mt. Mashu (857 m) and Mt. Shari (1,547 m) beyond, and on clear days even the Shiretoko Range — making this one of Hokkaido's most spectacular panoramic spots. From September to November on clear, windless mornings with a big temperature differential, a sea of clouds rises from Lake Kussharo and spreads beneath the pass, with Mt. Mashu's peak emerging above — a phenomenon often called «paradise in the sky.» The barrier-free observatory adjoins Michi-no-Eki «Gurutto Panorama Bihoro-toge.»
