Starting from the Ojirogawa Gorge, cross a suspension bridge from Chiku Komagatake Shrine and climb the Kurodo Ridge — one of Japan's three great steep ascents — to the summit. It is the sacred front approach, gaining more than 2,200 m of elevation.

Kaikomagatake is a "white granite mountain" standing in the northern Southern Alps. The Hokuto-based editor, who sees this mountain from home every day, actually climbed it by two routes and lays out the material for your decision. In the "climb records" tab above you can compare the hike replay, elevation profile, route map and photos for the Kurodo Ridge and Kitazawa Pass.
One is the Kurodo Ridge (the front approach) — a "great steep ascent of Japan" gaining over 2,200 m, attacked from Chiku Komagatake Shrine in the Ojirogawa Gorge across a suspension bridge. Above the Shichijo Hut at the seventh station, ladders, chains and rock faces come one after another; even the editor's measured time was a long haul of about 14 hours 13 minutes including breaks (depart 04:05, summit 12:22, descend 18:19).
The other is the general route from Kitazawa Pass — with a bus taking you up to about 2,030 m the elevation gain is small, and from the boulder field at Sensui Pass you cross Komatsumine to the summit. The editor's measured round trip was about 6 hours 36 minutes, a classic route well within reach of beginner to intermediate hikers. The same white summit shows this much variety depending on how you climb it.
Beginners should not force an attempt on the Kurodo Ridge; choose a Kitazawa Pass base. If you do the Kurodo Ridge as a day trip, commit to an early start, and if you cannot leave yourself time to spare, stay at the Shichijo Hut. In the snow season, also beware of icing and falls on the upper slopes.
Routes
The sacred front approach starting from Chiku Komagatake Shrine, and one of Japan's three great steep ascents. A long climb gaining over 2,200 m of elevation in one push; above the Shichijo Hut at the seventh station, ladders, chains and rock faces come one after another. With few escape options, it demands both stamina and rock-scrambling experience — a genuine test of fitness. The editor walked this route as a day trip.
Because a bus takes you up to Kitazawa Pass at about 2,030 m, the elevation gain is small and this route is far more accessible than the Kurodo Ridge. From the boulder field at Sensui Pass, cross Komatsumine to the summit. Often combined with Senjogatake, it is a classic route well within reach of beginner to intermediate hikers. The editor also reached the summit by this route.
History & culture
Kaikomagatake is a mountain long revered through the "Komagatake faith." The Kurodo Ridge, the front approach on the Yamanashi side, is said to have been opened in 1816 (Bunka 13) by the ascetic Kohan (Obi Gonzaburo) of Suwa in Shinshu. To this day, from the Komagatake shrines at Yokote and Chiku, stone monuments and Buddhist statues such as Fudo-iwa (Iryoku Fudoson) dot the route. Just below the summit stand a shrine of the Komagatake Shrine main hall and an iron sword, carrying down to today the history of a path of mountain asceticism.
It is a geologically special mountain, too. Amid the Southern Alps, where reddish-brown rock predominates, Kaikomagatake is one of the few "white granite mountains," ranking with the Hoo Sanzan. The white sand and weathered granite spread across the summit shine especially bright on a clear day.
The Kurodo Ridge is a long climb of more than 2,200 m of elevation, counted among "Japan's three great steep ascents." Following the sacred path from the Komagatake Shrine at the foot to the summit, gaining height step by step — that is the front approach to Kaikomagatake.
