Mt. Sugoroku, Mt. Mitsumata-renge, Mt. Kasagadake (Round Trip)

Starting from Shinhotaka Onsen (Hot spring), walk along the paved forestry road along left bank of the Gamata-gawa River. After crossing the bridge you will precede along a flat gravel forestry road along the right bank of the Gamata-gawa River. After passing where the road forks with Kasashindo you will arrive at the Wasabidaira-goya mountain hut, which is surrounded by a beech forest, about 90 minutes from Shinhotaka Onsen.

As the beech forest ends, you will come out onto a dry riverbed before arriving at where the course forks with the Mt. Okumaru (Okumaru-yama) trailhead. Proceed down the left fork onto the Koikeshindo. Proceed down the cobbled path through the meadow and hike up the rocky trail through the shrub zone. After crossing Chichibu-sawa and Chichibu-kosawa using the simple wooden bridge you will once again come to a rocky trail that continues for some time. As the surrounding area turns to meadows, you will arrive at Shishiudogahara where fields alpine plants bloom from July to August. There are also benches to rest on.

Proceed down the traverse trail from Shishiudogahara and after you pass the Kuma-no-odoriba boardwalk and hike up the rocky section you will arrive at Kagami-daira about 5 hours after leaving Shinhotaka Onsen. The area is dotted with little ponds along the boardwalk. Kagami-ike Pond is especially photogenic because of the way Yarihotaka mountain range is reflected in its surface. After you pass by the Kagamidaira-sanso mountain hut and hike up the rocky trail, the surrounding will change from a shrub zone to a stone pine belt. You will then traverse the right side of Mt. Yumiori (Yumiori-dake) before arriving at the Yumiori fork.

After hiking up and down the ridgeline through a stone pine belt you will pass through a meadow where alpine plants bloom from July to August. The trail will then turn into a landside scar that has been reinforced with wood. Once again a boardwalk will appear and you will pass through a flat stone pine belt before arriving at the Sugoroku-goya mountain hut. This is where you will stay the first night.

Starting early the second day you will start hiking up through the stone pine belt behind the Sugoroku-goya and pass the Makimichi fork, a traversing detour route, and the fork,a route through the mid-slope of the mountain, before proceeding down the rocky trail of the ridgeline route. As the surrounding area turns into a plateau dotted with stone pines and meadows you will arrive at the summit of Mt. Sugoroku about 70 minutes from the Sugoroku-goya. If you look back you will see the beautiful ridgeline of the Yarihotaka mountain range.

Proceed down the gently-sloping ridgeline through the stone pine belt and after you pass over Mt. Maruyama you will arrive at the summit of Mt. Mitsumata-renge about an hour after leaving Mt. Sugoroku. You will return to the Sugoroku-goya via a detour that traverses the left side of the ridgeline you walked to get here.

After returning to the Yumiori fork about 70 minutes from the Sugoroku-goya and taking the right fork, you will hike up and down a ridgeline that connects Mt. Yumiori, Mt. Onoma (Ohnoma-dake), and Mt. Nukedo (Nukedo-dake). After passing the Kasashindo fork and hiking to the top of the rocky trail stone pine belt following the paint marks, you will arrive at the summit of Mt. Kasagadake about 4 and a half hours from the Yumiori fork. You will stay the second night the second night at the Kasagadake-sanso mountain hut located just under the summit.

At the start of the third day, return to the Kasashindo fork and proceeds down the right fork onto the Kasashindo. Zigzag down the slope through the meadow and after you hike back up you will arrive at Shakushi-daira. Zigzag down the steep slope that changes from a shrub zone to a broadleaf forest and then to a conifer forest. You will arrive at the Kasashindo trailhead about 4 and a half hours from the Kasashindo fork.
Return to Shinhotaka Onsen via the flat forestry road you passed through on the first day.
