Mount Kamui, Mountain summit in Asahikawa, Japan

Mount Kamui is a 799.2 m peak in the Hōnai Mountains, in Kamui-chō, Asahikawa, near the border with Fukagawa. Its summit holds radio relay facilities and a former Self-Defense Forces post, while the western slope carries the Kamui Ski Links courses. An approach road runs from the Yūdono Kannon site along National Route 12 to the top.

Mount Kamui, 799.2 m high, lies in the northern part of the Horonai range between Asahikawa and Asahibetsu. Its summit was long used for radio and defence relay facilities, including the former Kamuiyama outpost of the Defence Agency, and the north slope held the state-run Kamuiyama ski area, part of which now forms the fifth lift and Dynamic course of Kamui Ski Links.

The mountain's name comes from the Ainu word kamui, meaning a divine being or spirit. The surrounding area also carries Ainu-derived names: Inosawa Peak nearby comes from the Ainu "irunai", meaning a valley with many bear tracks, the same root as Ina Station. The lower slopes are used in spring for picking bamboo shoots and warabi ferns.

There is no marked hiking trail to the summit; the approach runs from the Denden Kannon shrine area along National Route 12 up to the top. The slopes are brown bear habitat, and signs warning of bears stand on the forest roads from the foot of the mountain, with sightings reported. In spring locals come to the lower slopes to gather bamboo shoots and bracken.

The summit holds radio relay facilities and a Self-Defense Forces installation, the former Kamuiyama Detachment, placed there because the site suits broadcasting between the Sorachi and Kamikawa regions. Below, on the west slope, run the Kamui Ski Links courses; a sign at the trailhead warns of brown bears, which live in the area.
