Mt. Kawanoriyama (川苔山) is a 1,363m mountain in the Okutama area of western Tokyo. Known for the spectacular 40-meter Hyakuhiro Falls (百尋ノ滝) and beautiful valley scenery along the trail, it is one of the most popular mountains in the Okutama region. The fresh green season and autumn foliage are especially recommended.

From JR Okutama Station (奥多摩駅), take a bus to Kawanoribashi (川乗橋) and hike to the summit via Hyakuhiro Falls — the most popular route (approx. 3 hours 40 minutes to the summit). You can also start directly from Hatonosu Station (鳩ノ巣駅, approx. 3 hours 15 minutes) or Kori Station (古里駅, approx. 3 hours 45 minutes).

The Kawanoribashi trail offers scenic valley walking, with the section up to Hyakuhiro Falls being the highlight. Beginners can enjoy a round trip to the falls. A popular option is to descend to Hatonosu Station for a loop route.

From Kawanoribashi to the trailhead (Hosokurabashi)

There is no trail entrance at the Kawanoribashi bus stop. From the gate beside the stop, walk about 2.5 km / 45 minutes along the paved Kawanori forest road to Hosokurabashi, the effective start of the popular route via Hyakuhiro-no-Taki falls. Add this road walk to your round-trip course time. The routes from Hatonosu or Kori stations, by contrast, begin climbing right from the station.

Note: The Kawanoribashi bus stop may be skipped (no stop) due to road collapses or similar issues; in that case, get off at the earlier Osawa bus stop. The Kawanori forest road (Kawanoribashi–Hosokurabashi) and the trails along the Kawanori-dani valley have been closed by landslides in the past, so before heading in, be sure to check the latest stop status and passability with Nishitokyo Bus service information and the Okutama Visitor Center.

Mt. Kawanoriyama Hiking Routes, Difficulty & Best Season

Mt. Kawanoriyama rises to about 1,363 m in the Okutama area of western Tokyo, prized for the 40-meter Hyakuhiro Falls and the valley scenery along the way. The classic route starts at the Kawanoribashi bus stop, passes Hyakuhiro Falls on the way to the summit, and then descends to Hatonosu Station on the far side.

Main route

  • Kawanoribashi bus stop → Hyakuhiro Falls → Mt. Kawanoriyama → Hatonosu Station: about 13.0 km / cumulative elevation gain about 1,189 m / time about 8 hours (476 minutes) / difficulty: intermediate. This point-to-point route follows the valley past several stream crossings and rocky sections near the falls before climbing to the ridge, so the distance makes it best suited to fit, experienced hikers. Shorter approaches starting directly from Hatonosu or Kori stations are also available (see the access sections above).

Difficulty & fitness

The overall distance is long and includes stream crossings and slippery rock near Hyakuhiro Falls, so it is not a good first hike for complete beginners. Start early if you are doing it as a day hike, and turn back rather than forcing a crossing if the stream is running high after rain.

Best season

From the fresh greenery of spring to the autumn foliage of late fall (roughly April to November) is the most comfortable time to go. Because the trail follows a valley, watch for high water after heavy rain, and carry light crampons for icy sections in winter (roughly December to March).

Highlights

The 40-meter Hyakuhiro Falls and the valley scenery along the Kawanori-dani gorge are the main highlights, with sweeping views over the Okutama mountains from the summit.
