The Tanzawa mountain range is a generic term for mountains located in the northwest part of Kanagawa Prefecture, spanning approximately 40 kilometers east to west. The range is designated as the Tanzawa-Oyama Quasi-National Park and selected as one of Japan’s 100 most famous mountains. Mt. Hirugatake is the highest peak, with Mt. Tanzawa (Tanzawa-san), the representative of the mountains located to its southeast, and Mt. Tonodake (Tohno-dake) further south. This trip introduces the so-called Tanzawa main mountain route, which takes the less-difficult Okura-one ridge from the south to Mt. Hirugatake.

From Okura bus stop, walk on the paved road to get to the Okura trailhead. The trail divides, but either way will get to Komadome-chaya mountain hut in approximately 40 minutes via Miharashi-chaya mountain hut.

Proceed up a steep slope, and the ridgeline will become flatter after passing Komadome-chaya mountain hut. It takes approximately an hour and 10 minutes to reach Horiyamano-Ie mountain hut.

After hiking up the rocky section, the trail becomes flatter again near the Tenjin-one Fork, then turns into a steeper slope with landslide prevention fencing before reaching Hanatate-sanso mountain hut. After hiking down on a flat wooden path from Hanatate for approximately an hour and 15 minutes, hikers will arrive at the col named Kinhiyashi. Go back up the staircase and Mt. Tonodake, where Sonbutsu Sanso mountain hut sits, is approximately 25 minutes away.

Descend on the wooden path over a peak called Hittaka, and the trail continues onto a scenic bamboo grass field on a ridgeline, which eventually leads to the peak called Ryugabanba in approximately an hour and 10 minutes.

Proceed on the ridgeline with deer prevention fencing, and it takes approximately 30 minutes to get to Mt. Tanzawa, where hikers will spend their first night at the Miyama-sanso mountain hut located on the summit.

Day 2 starts heading towards Mt. Hirugatake. Descend on the steep wooden path through a bamboo grass field over the peak named Fudohno-mine with a rest area, and hikers will arrive at another peak called Tanasawano-atama in approximately an hour. From the peak named Onigaiwano-atama, descend on the chain-supported part and hike up a gentle slope, and Mt. Hirugatake is approximately an hour away.

Take the same path for the return trip.

Other Info

The ridgeline of Mt. Tonodake above the tree limit is a shrub zone among a bamboo grass field and is very scenic. Especially the west side has Mt. Fuji in sight, offering beautiful views of the mountain with snow on top around December on a sunny day with clear air.

High Season:November to May


Land leech breeds in the Tanzawa mountain range during the warm season from around May to October. They climb up on the feet of hikers from the ground and suck on blood. Utilize salt provided at Hadano Visitors Center or leech repellent available at mountaineering equipment shops to take precautions before hiking.
