Shōmyō Falls are located in the town of Tateyama, Toyama Prefecture, Japan. Shōmyō-daki is the highest waterfall in Japan at 350 m. The falls have four stages: the first 70 m, the second 58 m, the third 96 m and the last 126 m high. The greatest amount of water flows over the falls in the early to mid-summer, when the snow in the Tateyama Mountains melts.
