Hossawa Falls is the only waterfall in Tokyo Prefecture designated as one of Japan's Top 100 Waterfalls.
The name 'Hossawa' is derived from a local legend involving a mythical serpent or dragon dwelling in the basin of the falls.
During peak winter months, the falls are known to freeze completely, a phenomenon monitored by local tourism officials.
The waterfall consists of four distinct levels, though only the lower tiers are easily accessible and visible from the observation deck.
Hossawa Falls is a four-tiered waterfall located in the village of Hinohara, representing the only waterfall in Tokyo included in Japan's Top 100 Waterfalls list. The total drop of the falls measures approximately 62 meters, with the lowest tier being the most visible to the public. Access is provided via a maintained gravel and stone walking path that spans about 15 minutes from the trailhead to the viewing platform. The area features a natural pool at the base of the falls where freezing occurs during mid-winter, creating an ice pillar formation. It serves as a primary natural attraction in the mountainous western region of Tokyo Prefecture. The path follows the course of the Hinohara River tributary through a forested valley floor.
The wooden observation deck at the end of the trail provides a head-on view of the lowest tier.
Wear sturdy, closed-toe walking shoes as the trail can be slippery or uneven after rainfall.
Carry insect repellent if visiting during the humid summer months.
Visit on a weekday to avoid congestion on the narrow path.
Attempting to swim in the waterfall basin, as it is prohibited and dangerous.
Stay on the designated gravel path and do not attempt to climb the rock face surrounding the waterfall.
