Introduction of the Trails for Mt. Komagatake

Agematsu Course A for Mt. Kisokomagatake

This is the main route from Agematsu Sta. to Mt. Komagatake via Mt. Kisomaedake . It became so popular, following Walter Weston’s use of the route, that there was once a busy bus service running here.

It is an 8-km, 8-hour hike from the Alps Hut at the second station.

Until Kanakake Refuge Hut at the fifth station, the path is rather steep. There used to be a water supply “Kongosui” at this fifth station, but it is now often dry. So, the last water supply should be at Keishin, the third station. There are no staff at Kanakake Refuge Hut, and anybody is free to use it.

The Onagi Route on Mt. Kisomaedake is collapsing, so please watch your step.
Agematsu Course B for Mt. Kisokomagatake

This route starts from Agematsu Sta., proceeding through the Ashijima Area, then up Mt. Mugikusadake to the peak of Mt. Kisokomagatake via the traversal of some other peaks.
Compared to Course A, there are fewer climbers. However, the dynamic views of Kibiyo Falls that appear on the way are superb, meaning that there are some admirers of this route.

Kisokoma Hut at the trail entrance is the center of the “Kisokoma JOY” project for renovating huts.

Many climbers take the forest road from Kisokoma Hut to Kibiyo Falls. There are some collapsing points on the forest road though, where you should use a bypass trail.

From Kibiyo Falls, it gets steep, just like a normal mountain trail. Soon after you get above the tree line, the view expands, and the hilly summit of Mt. Mugikusadake appears before you.

From Mt. Mugikusadake to Mt. Kisomaedake, you climb the ridge. This part is especially difficult to pass, even for experienced climbers, because of some extensive collapsed sections. Watch your step very carefully.
Mt. Utsugidake Course

This route climbs to the famous southern peak of the Central Alps, Mt. Utsugidake, starting from Kuramoto Sta. up to Umanose through Nakahatcho Pass, a long hike of more than 10 km.

From Kuramoto Station, you walk through a residential area. Then you will find the box for submission of your mountain climbing plan. From there, you have to climb up all the way to Nakahatcho Pass. As you go down from the pass, you move from Agematsu Town into Okuwa Village. The path leads you to a forestry road until Usagidaira where some climbers bivouac to recover.

From Usagidaira, you have to climb on a steep path. With Mt. Higashigawadake on your right, you aim for Kisotonokoshi ridge. “Kisotono” refers to the samurai general Yoshinaka Kiso of 12th century, who is said to have crossed the Central Alps over this ridge. Here stands Kisotono Mountain Hut, the last hut before the peak.

From Kisotonokoshi to Mt. Utsugidake is a rather short distance. The route from Mt. Utsugidake to Mt. Kisokomagatake is along the ridge, taking even an experienced climber about 6 hours.

About Mt. Kazakoshi Mountain Trail

Mt. Kazakoshi is a typical Satoyama (an inhabited mountainous area). It used to be tightly associated with communities such as the Yoshino Area at its foot. It was their precious resource for living where they could get grass for their livestock, roofing material, or food. The history has been traced back to ancient times, and some earthenware and stone tools were excavated in this area. When you visit the Yoshino Area, you can see Mt. Kazakoshi, which looks as if it is guarding this peaceful rural village.

This mountain and its periphery are counted among the 8 best views of Kiso in the Edo Period, celebrating the beautiful grass fields of summer time with a pleasant wind softly caressing them. However, as modernization proceeded in this area, the grassland started to reduce with less human engagement with the mountain, resulting in the loss of the scenery. Now, the grassland area only remains at the top, leaving the other parts covered with miscellaneous bushes.
Mt. Kazakoshi used to be covered with grass fields until around 1965. The residents once tried to get back to the old beautiful landscape.

Trail Map Course B

Course B bypassing on the right side of the mountain is currently in the process of development. Course A, that climbs vertically to the top, is rather bushy.

On the slope, a cable that was used to convey trimmed grass or wood is still in place, so watch your step.

*Hunting is permitted from Mid-November to Mid-February. For your own safety, please refrain from climbing during this period.
