This waterfall on the Ogata Plain in southern Oita is nicknamed the "Niagara Falls of Japan" for its distinctive horseshoe shape, though these falls are much smaller. Formed by the great eruption of Mt. Aso 90,000 years ago, the falls are around 20 meters high and 120 meters wide. The surrounding flatlands make the falls more impressive, as they seem to appear out of nowhere.
A suspension bridge offers a great vantage point over the whole area, leading to a path right across the top of the falls.
Near the entrance to the waterfall area, there is a restaurant serving local specialties. A path leads from the restaurant to the basin below, where you can stand on a small outcrop with the falls surrounding you.
