Harajiri Falls (原尻の滝, Harajiri-no-taki) is a waterfall located on the Ōno River in Ogata Town, Bungo-Ōno, Ōita Prefecture. It was selected by the Japanese Ministry of the Environment as one of the top 100 waterfalls in Japan.
Harajiri Falls is 20 meters tall and 120 meters wide. Due to its appearance, it is sometimes referred to as the "Niagara Falls of the East."[1] The waterfall was formed from the pyroclastic flows of an eruption of Mount Aso about 90,000 years ago.[2]
There is a 90-meter-long wooden pedestrian suspension bridge downstream from the falls which offers a view of the waterfall for visitors.[3]
Located near the falls is a Michi no Eki (roadside station) which sells various local specialties.
