History & Origins
The heart of Towada-Hachimantai National Park, Oirase Gorge gained wide recognition for its scenic beauty from the Meiji period onward. It is also associated with the celebrated Buddhist nun and novelist Jakucho Setouchi.
Highlights
Stretching 14 km, the gorge is dotted with spectacular sights: the Asura-no-Nagare rapids, Kumoi Falls, and Choushiootaki Falls, among many others. A well-maintained riverside walking trail makes it easy to explore on foot.
Visitor Guide
The full course (14 km) takes 3–4 hours. Most visitors take a bus to one end and walk in one direction. Early morning, when mist floats through the gorge, is an especially magical experience.
Best Season
May for fresh greenery and late October to early November for autumn foliage at its peak.
Annual Events
- November
Oirase Gorge Eco-Road Festa
A nature experience event held every year to coincide with the autumn foliage season in November. Part of the road along the stream becomes reserved for pedestrians and bicycles, so visitors can enjoy the autumn scenery of the gorge without worrying about cars.
