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

It is the uppermost stream of Oirase River flowing from Lake Towada and into Pacific Ocean.
Oirase River is the only river flowing out from Lake Towada.

There are many various waterfalls along this stream.
We can enjoy the scenery that clean water flows and the forest bathing.

The area is from Nenokuchi (子ノ口) to Yakeyama (焼山).
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 Towadako onsen (十和田湖温泉), additionally there is a ski resort.

A paved road and a walking trail are set up along this stream.

The route buses between Lake Towada and Aomori city or Hachinohe city run on this paved road 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.
Because Yakeyama is about 200 meters lower than Nenokuchi, it is 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.

There is Ishigedo (石ヶ戸) spot about 8.9 km from Nenokuchi.
There is no house in Oirase, but a small rest facility with shop and parking is put only at Ishigedo.
