Hannoki Falls, Seasonal waterfall in Toyama Prefecture, Japan
Hannoki Falls is a seasonal waterfall in Toyama that flows from April through July, descending over several hundred meters from the Midagahara plateau. The water supply comes entirely from snowmelt, so the visible power of the cascade changes significantly as conditions vary through the season.
The waterfall received its name during the Edo period when the surrounding region was known for its natural resources and mountain passage location. The falls in this area later influenced the development of local routes and infrastructure in the mountain region.
The waterfall takes its name from Japanese alder trees that once grew along the surrounding cliffs. Local residents view the return of water each April as a sign that mountain activities can resume for the season.
This waterfall can only be visited between April and July when snowmelt water flows down from the plateau. It is wise to check weather conditions before traveling, as visibility of the falls may be limited during heavy rain or overcast skies.
This waterfall forms a natural pair with neighboring Shomyo Falls, creating a rare configuration where two major cascades face each other across the landscape. This natural pairing is uncommon in Japan and creates a distinctive visual feature in the mountain scenery.
