Plan this hike

Hiking time is an estimate for an average hiker, without breaks.

This classic out-and-back route climbs through beech forest from Koderakōsen Trailhead, crosses Mount Kodera and Mount Ko-Asahi, and reaches Mount Ōasahi, the highest summit of the Asahi range. Early-summer Himesayuri lilies line sections of the upper ridge, which passes the summit shelter before reaching the 1,871-metre peak and its far-reaching view across the remote range.
