Oirase stream

Oirase stream mapOirase stream Oirase stream is one of the most popular sightseeing spot in Aomori Prefecture, and espacially many tourists visit here during the season of new green leaves and autumn leaves.

It is the uppermost stream of Oirase River, which flows from Lake Towada and into Pacific Ocean.
There are many various waterfalls along this stream, so we can enjoy the scenery that clean water flows and the woodsy fragrance.

The area is from Nenokuchi to Yakeyama, and the distance is about 14 km.
Nenokuchi is a small town on the east coast of Lake Towada, and here is the starting point of Oirase River.
Yakeyama is a hot spring resort town, which is also called "Towada-ko onsen", additionally there is a ski resort.

A pavement and a walking trail are all along this stream.
The route buses between Lake Towada and Aomori or Hachinohe run on this pavement once or twice every hour. So if you make good use of them, you may tour here effectively.

When you plan to walk all along this stream, you should allow 5 hours. Yakeyama is about 200 meters lower than Nenokuchi, then, of course, it's easier to walk from Nenokuchi.

Using a rental bicycle is a good idea. There are some shops for it at Nenokuchi and Yakeyama.
If you rent a bicycle at Nenokuchi, you can pedal on down slope. Even in that case, you can return the bicycle at Yakeyama.
