Oirase Gorge (奥入瀬渓流, Oirase-keiryū) is a stunning highlight of Towada-Hachimantai National Park.

 

Situated on the border between Akita Prefecture and Aomori Prefecture in northern Japan, this picturesque gorge is the only stream flowing out of Lake Towada, a beautiful caldera lake formed by volcanic activity.

 

Stretching approximately 14 km from the lakeshore, Oirase Gorge offers a delightful escape into nature, showcasing the breathtaking scenery and vibrant landscapes that make this area special.

 

As you wander in picturesque paths, prepare to immerse yourself in a world where tranquility reigns and the beauty of Japan’s wilderness is on full display.

The gorge is covered by dense trees and is lined with azaleas and maples. Mossy rocks surround the area, creating a picturesque walking path rich in nature. 

 

Along the way, there are many waterfalls and dynamic flows of water, along with various unique rocks that create a magnificent river landscape.

 

This place is famous among poets, artists, hikers and cyclists alike because the forest emanates soothing negative ions, and the scenery can make those who walk enter an almost meditative state.
