The canyon features the 'Jingoji' or 'Fudo' waterfall, which stands approximately 40 meters tall.
The Ojira River is frequently used as a primary water source for the famous Hakushu distilleries located in the vicinity.
The geological composition of the canyon is dominated by crystalline granite, which contributes to the high clarity of the river water.
The valley trail is a segment of the traditional mountain climbing path toward the summit of Mount Kaikoma.
The canyon is situated within the Minami-Alps National Park region.
Ojiragawa Canyon is a scenic valley carved by the Ojira River, originating from the granite massifs of Mt. Kaikoma in the Southern Japanese Alps. The area is defined by its deep emerald-green pools, massive granite boulders, and a series of waterfalls, most notably the Fudo Falls. Visitors traverse the canyon via a well-maintained trail system that includes steel suspension bridges and staircases. The river water is famously clear, often cited for its purity, as it is sourced from the glacial-fed heights of the mountain range. The surrounding topography consists of steep, forested slopes providing significant canopy cover along the lower sections of the trail.

Wear footwear with high-traction rubber soles, as the granite surfaces become extremely slippery when wet.
Bring an insect repellent, as the humid, wooded environment supports high mosquito and fly activity during summer months.
Carry all trash out of the valley, as there are no waste disposal facilities on the trail.
Do not attempt to swim in the deep pools during periods of heavy rainfall, as the canyon is prone to sudden, dangerous surges in water levels.
Trail access may be restricted during winter months due to snow and ice; check for local mountain trail conditions before visiting.
Stay strictly on the marked trail to prevent erosion and avoid disturbing the fragile riverbank vegetation.
