The Ishibune Bridge is a pedestrian-only suspension bridge that spans 96 meters across the Akigawa River.
Akigawa Valley is located within the Chichibu-Tama-Kai National Park, which covers parts of Tokyo, Saitama, Yamanashi, and Nagano prefectures.
The valley is a primary site for Ayu (sweetfish) fishing, with the season typically opening in late spring.
The Akigawa River is one of the largest tributaries of the Tama River, which supplies a significant portion of Tokyo's drinking water.
The geological composition of the valley features strata dating back to the Paleozoic and Mesozoic eras.
Akigawa Valley is a scenic gorge carved by the Akigawa River, located within the foothills of western Tokyo. The valley is characterized by its limestone formations and clear river water, serving as a popular destination for seasonal river fishing and hiking. Its most recognizable feature is the Ishibune Bridge, a suspension bridge providing a panoramic view of the river and surrounding forest. The area falls within the Chichibu-Tama-Kai National Park boundary, preserving a more rustic, mountainous landscape compared to central Tokyo. The gorge features multiple trekking paths that follow the riverbanks, connecting various points of interest including small cafes and stone statues. The valley is known for its biodiversity, particularly its autumn foliage and cool river breezes during the summer months.

Wear footwear with strong grip, as riverside paths can be uneven and occasionally slippery.
Bring a waterproof bag if you plan on exploring the rocky banks of the river.
Pack a light jacket, as temperatures in the valley are often several degrees cooler than in central Tokyo.
Do not attempt to hike the riverside trails during or immediately after heavy rainfall due to the risk of rising water levels.
Some riverside campsites and fishing facilities operate seasonally from spring through early autumn.
Carry all trash back with you; swimming in non-designated areas and loud music are prohibited to maintain the natural environment.
