What is the height of Japan’s tallest waterfall, Shōmyō Falls?

Shōmyō Falls is 350 metres high, making it Japan’s tallest waterfall by total drop.

The falls are in Toyama Prefecture, near the Tateyama mountain area. Shōmyō River descends through a series of cascades before reaching the lower valley, with the complete fall measured across several stages.

Shōmyō Falls is sometimes discussed alongside Hannoki Falls, another major waterfall in the same region. Hannoki can become especially prominent during snowmelt, but Shōmyō is generally identified as Japan’s highest waterfall when permanent flow and total height are considered.

The name is associated with Buddhist chanting, reflecting the resonant sound traditionally linked with the falling water. The surrounding Tateyama landscape is also known for deep winter snow and dramatic alpine scenery.
