Japan · Toyama Prefecture
Hannoki Falls, in Toyama Prefecture, Japan, is the tallest waterfall in Japan at a height of 497 m . However, it is a seasonal waterfall, which only has water from April to July when the snow covering the Midagahara plateau melts, so its neighbor, Shōmyō Falls, is usually considered the tallest.
Facts from Wikidata and Wikipedia, compiled September 2026; season and access are our estimate, not a visit report. How we build these pages.
Hannoki Falls drops 497 metres (1,631 ft), inside Chūbu-Sangaku National Park. It is a plunge-type fall, and the nearest base for a visit is Tateyama, Japan. Access to the main viewpoint is rated moderate.
Summary adapted from the Wikipedia article (CC BY-SA 4.0).
Hannoki Falls is the tallest of the 44 waterfalls we cover in Japan. As a plunge waterfall, water leaves the rock entirely and falls free through the air.
No commercial adventures run at Hannoki Falls itself — the experience is the approach and the view. Guided day trips from Tateyama are the easiest way to combine it with the area around it.
