Hannoki Falls, Seasonal waterfall in Toyama Prefecture, Japan
Hannoki Falls is a seasonal waterfall in Toyama Prefecture that drops down from the Midagahara plateau, fed entirely by snowmelt. The flow is strongest in the early weeks of spring and gradually weakens as the season progresses toward summer.
The waterfall got its name during the Edo period, when the surrounding mountain region was known as a passage through the peaks. The presence of the falls in this valley later influenced how local paths and routes through the mountains were laid out.
The name of this waterfall comes from the Japanese word for alder, a tree that once grew along the surrounding cliffs. Visiting in spring gives a sense of the mountain season opening up, as the water returns and the trails around become accessible again.
The waterfall is only visible between April and July, so planning the visit around that window is essential. Going earlier in the season gives a better chance of seeing the flow at its fullest, before the snowmelt slows down.
Hannoki Falls and the nearby Shomyo Falls face each other across the same valley, which is a rare layout for two major cascades anywhere in Japan. Standing at the right point, a visitor can take in both falls at once, something that is hard to find elsewhere in the country.
