Janokuchi Falls

Janokuchi Falls in the southern part of Yakushima, a World Natural Heritage site, is a hidden wilderness waterfall that spreads out deep beyond a subtropical primeval forest. It appears at the end of a trekking course of about 3.5 kilometers one way from a trailhead near Onoaida hot spring, where a clear stream slides gently down smooth granite. Even on Yakushima, which sees many tourists, few people come here, making it a little known power spot where you can feel the power of nature in the silence.

Highlights

- The graceful and unusual sight of water sliding down a broad, flat face of granite. - The subtropical primeval forest unique to Yakushima. The walk through woods covered in ferns and moss is itself a highlight. - The clear mountain stream flowing before the falls. Its transparency is astonishing. - A special stretch of time facing the falls in the quiet, with few other visitors around.

Enjoying the Seasons

On rainy Yakushima the flow increases after rain, giving the falls a richer expression. In the fresh green season the forest greenery deepens, and in summer the coolness of the clear stream feels pleasant. Yakushima weather changes quickly, so visiting when there is a break in the clouds lets you fully enjoy the beauty of the forest and the falls.

Access and Basic Information

- Location: Yakushima-cho, Kumage District, Kagoshima (Onoaida area) - Trailhead: the Onoaida path entrance beside the Onoaida hot spring parking area - About 3.5 kilometers one way to the falls, about 4 to 5 hours round trip. Difficulty is intermediate - Public transport access is difficult, so a rental car is recommended

A Quick Tip

This is a serious trek that takes nearly half a day round trip, so be sure to bring hiking boots, plenty to drink and rain gear. When the weather turns, the streams can swell, so it is important to be willing to turn back rather than push on. After descending, a rest at the nearby Onoaida hot spring is recommended.
