The gorge is part of the Chichibu Tama Kai National Park, which spans across four different prefectures.
The Nanatsugama-Godan Falls creates a distinct five-step staircase effect that is frequently featured in landscape photography.
The route includes tunnels and remains of a logging railway system that operated in the area until the late 1960s.
The water clarity is attributed to the surrounding granite basin, which minimizes sediment runoff into the river.
The area is specifically recognized for its vibrant autumn foliage, drawing significant crowds during late October.
Nishizawa Gorge is a 10-kilometer hiking circuit located in Yamanashi Prefecture, famous for its series of multi-tiered waterfalls and clear mountain streams. The trail follows the Fuefuki River, featuring notable cascades such as the Nanatsugama-Godan Falls, designated as one of Japan's top 100 waterfalls. The path incorporates sections of a former forest railway track used during the Taisho and Showa eras to transport timber. Hikers traverse a mix of forested mountain slopes and deep river canyons. The terrain is rugged, involving elevation gains that require steady footing and physical endurance. The landscape is particularly noted for its granite rock formations and dense canopy cover.

Wear sturdy, waterproof hiking boots with high-traction soles as the trail can be slippery near the water.
Pack a light windbreaker or extra layer, as the temperature inside the deep, shaded canyon is significantly lower than the trailhead.
Carry sufficient water and snacks, as there are no food vendors available along the actual trail loop.
Attempting the full loop without adequate preparation, specifically failing to wear proper hiking footwear or overestimating fitness levels for the moderate incline.
Closed during the winter months (typically late November to late April) due to hazardous snow and ice conditions on the trail.
Stay strictly on marked paths to prevent erosion and avoid disturbing the local flora and fauna; do not swim in the waterfalls.
