Sekihoku Pass, Mountain pass between Kamikawa and Kitami, Japan.

Sekihoku Pass is a mountain pass on National Route 39 at an elevation of 1,050 m, on the boundary between Kamikawa and Kitami. The Kamikawa side drains via the Ishikari River to the Sea of Japan, while the Kitami side drains via the Tokoro River to the Sea of Okhotsk. Its vegetation resembles that of a 3,000 m environment.

The pass lies on National Route 39, the shortest route between Asahikawa and Kitami. Its name takes one character each from the old provinces of Ishikari and Kitami, and it now marks the boundary between the Kamikawa and Okhotsk subprefectures. The summit sits at 1,050 m, and the upper section can see snowfall even in mid-June.

The name Sekihoku combines one character each from Ishikari and Kitami, the old provinces the pass links; it now marks the boundary between the Kamikawa and Okhotsk subprefectures. The pass also appears in the song "Sekihoku-tōge" (lyrics by Takaharu Takagi, music by Mayumi Kuwayama), covered by Hiroaki Shimizu in 2012.

Sekihoku Pass lies on National Route 39, the shortest route between Asahikawa and Kitami. From the summit, a 19.2 km stretch on the Kamikawa side closes when rainfall reaches 100 mm; adjacent sections totalling 9.9 km on the Kitami side and 6.9 km on the Kamikawa side are subject to advance closure when patrols predict danger. Snow can fall at the top even in mid-June.

The pass shifts through four distinct seasons: snow-covered terrain in winter, wildflower meadows in spring, thick forests in summer, and colorful autumn foliage. Each season offers a completely different experience when you visit.
