Oirase Gorge is a scenic area located in Aomori Prefecture, in the northern region of Japan's Honshu island. The area is characterized by a winding stream that flows through a narrow, forested valley, forming a series of rapids, waterfalls, and tranquil pools.

The Oirase stream runs for 14 kilometers from Lake Towada, one of the largest caldera lakes in Japan, down to the Pacific Ocean. Along the stream, visitors can enjoy hiking trails, observation decks, and bridges that offer views of the beautiful natural surroundings.

In autumn, the Oirase Gorge is particularly renowned for its vivid fall foliage, when the leaves of the trees lining the river turn brilliant shades of red, yellow, and orange. In spring, the cherry blossoms add an additional layer of beauty to the area. The gorge is also home to a variety of flora and fauna, including beech trees, Japanese macaques, and trout.

The Oirase Gorge is a popular destination for hiking, nature walks, photography, and fishing. Visitors can take a bus or taxi from the nearby city of Aomori, or rent a car to explore the area at their own pace.
