Hayato Great Falls

Hayato Great Falls is a waterfall on the Hayato River within the boundaries of the Tanzawa-Ōyama Quasi-National Park, in Sagamihara, Kanagawa Prefecture, Japan.

The Hayato Great Falls has a large volume of water, and drops in two separate plunges with a total height of 50 metres. The upper falls has a height of 40 meters, and the lower has a height of 10 meters. The view is blocked by a great rock protruding from the middle of the upper fall, so that the whole waterfall can be seen clearly only from the bottom. The Hayato Great Falls is located deep within Tanzawa Mountains, and is accessible only by a two-hour hike on poorly marked and maintained mountain trails from the nearest road. It is inaccessible during inclement weather, and thus has few visitors.
