Otodome Falls, Waterfall in Fujinomiya, Japan.

Otodome Falls is a waterfall on the Shiba River in Fujinomiya, dropping about 25 meters. The water springs from a narrow lip of dark, moss-covered rock and splits into several white streams that widen as they fall, breaking into spray above a dark green pool. Two thin side channels slip down the shadowed rock on the left, and a faint rainbow arcs across the mist on the right.

This location has been known since the Kamakura period, when the Soga brothers used the sound of the falling water to conceal their voices during secret planning. This historical connection shows how the waterfall has served practical purposes for people over many centuries.

The name Otodome, "sound-stopping", comes from the Soga Monogatari: the Soga brothers, plotting to kill Kudō Tsuketsune, could not hear each other over the falls and prayed until the roar ceased. East of the falls stands the Soga-kakure-iwa, the rock where they are said to have hidden.

Getting there is straightforward with bus service from Shin-Fuji or Fujinomiya stations running several times daily. Designated viewing areas let you see and photograph the waterfall from the best angles.

Otodome Falls is one of Japan's Top 100 Waterfalls, a list published by the Ministry of the Environment in 1990; the nearby Shiraito Falls is on the same list. The two falls, about a five-minute walk apart, contrast sharply: Otodome drops roughly 25 metres in a forceful single curtain, while Shiraito falls as many fine threads.
