Mount Shiraga, Mountain summit in Kami, Japan

Mount Shiraga is a 1,770 m peak in the Tsurugi Mountains of Kami, Kochi Prefecture, rising on a southern spur of the ridge linking Mount Tsurugi and Mount Miune. Its summit is a grassy meadow with a small pond, Shiraga-ike, just west of the top, and a rocky outcrop called Kita no Terrace slightly north. The mountain's east side forms the source of the Monobe River, while the west side drops into the V-shaped Nishikuma Gorge.

The origin of the name Shiraga is uncertain. One explanation says the peak was named for the white dead trees on its summit, which look like white hair; another suggests the winter snowcap gave the mountain its name. The mountain lies in the Tsurugi range and is included in the Quasi-National Park and the Miune scenic forest.

The name Shiraga-yama is of uncertain origin: one explanation says the dead white trees near the summit make it look as if white hair has grown, another that winter snow whitens the top. To distinguish it from a 1,470 m namesake in Motoyama, this one is also called Monobe no Shiraga-yama.

Hiking this peak requires appropriate gear and careful weather monitoring, as the elevation and forested routes demand proper preparation. Multiple marked trails lead to the summit and allow visitors to choose routes based on their experience level.

The summit's triangulation point is officially named Shiraga-yama and was resurveyed in December 2024 at 1769.80 m, slightly below the often-quoted 1770 m. The peak lies within the Tsurugi Quasi-National Park and the Miune Scenic Forest, a 1,511-hectare reserve. The mountain's name may come from the white dead trees on the summit, which resemble white hair.
