Overview & Charm

Oshirogawa Valley is located in Hakushu Town, Hokuto City, Yamanashi Prefecture, with its headwaters originating from the Southern Alps' Mount Kaikomidake. The area is officially selected as one of the "100 Best Waterscapes in Japan," making its water clarity truly exceptional. The sight of translucent emerald green water flowing over white granite riverbeds is a mesmerizing experience for all visitors. Depending on your skill level, you can enjoy everything from a gentle stroll to the easily accessible Senga-fuchi to a more challenging trek toward Fudo Falls, which requires proper hiking gear.

History & Culture

The area has long been cherished for its rich natural environment within the Southern Alps. At the entrance to the valley, the Takeu Komagatake Shrine stands as a guardian of the area. Historically, this site has been a place of reverence for nature, where people have come to pray for safety and seek spiritual healing through the pure, flowing waters.

Key Highlights

Seasonal Recommendations

The landscape changes beautifully with the seasons. The vibrant fresh greenery of early summer and the colorful autumn foliage (typically late October to early November) are must-see periods. Please note that the valley paths are closed during the winter season (mid-December to mid-April).

To avoid crowds, we recommend arriving early in the morning (by 9:00 AM), especially during the summer and autumn seasons. Parking lots often fill up by the afternoon, so please plan your trip accordingly.
