Watch the sunlight dancing on the water as it flows over Ryujin Waterfall. Look out for pretty rainbows in the mist.
When you've finished up at this cascade of water in Hinohara, why not make your way to Okutamaonsen Moegi Hot Spring, Lake Okutama, and Forest of Tokyo Citizen? They're not too far from Ryujin Waterfall and also a favorite with many travelers.
