Oirase Stream

Oirase Stream

The Oirase Mountain Stream is the only outflow of water for Lake Towada and is one of the best places to see autumn colors.

The Oirase Mountain Stream (奥入瀬 渓流, Oirase keiryuu) is found in the prefecture of Aomori and possesses a colorful and generally pleasing ambience due to the virtually untouched forestry and foliage in that area, making it a popular destination for fall season. Oirase is not only preserved for its distinctive picturesque spots and its trees like the Japanese beech, white cedar, and maple trees, but also because of its various waterfalls seen along the road. The stream was created by rocks and sand from a volcanic eruption. The Oirase Mountain Stream is part of the Towada- Hachimantai National Park and has been designated a Natural Monument. Tourists and sightseers can go to Oirase and enjoy the views while riding a bike, hiking along the trail, riding a bus or car, though it can become dangerous for pedestrians who walk or bike on the trails that sometimes cross roads with the vehicles. In such cases, during particular times of the year (mainly during tourist seasons) the road is closed off to vehicles for safety, but alternate roads and options can be used instead to adjust for other sightseers who want to see the waterfalls and natural settings of the Oirase streams. The streams start from Nenokuchi, a small town in Lake Towada and ends at Yakeyama, a hot spring resort. The water flowing out from Lake Towada makes the Oirase stream possible. The Oirase Mountain Stream is also the only flow of water coming from Lake Towada. The stream is approximately 9 kilometers (more than 5 miles) one way and is normally walked in about 2 and a half hour. However, the more distinguished waterfalls that visitors might want to visit first are the Kumoi-no-taki Falls, or Chosi-otaki Falls among others, since some of the main waterfalls have a more characteristic water flow in either the forms they give or the amount of water that streams from them.
