Oirase Stream is all of our property.
Everyone has the right to enjoy it.

On the other hand, a rise in vehicles pour in during the tourist season causing various problems, such as traffic congestion and other environmental concerns. Also, the National Highway No.102 along the mountain stream doubles as a local road with an industrial area because a segment of the road bypasses a mountain stream leading to difficulties passing large-size vehicles.

To solves these problems ˹ The Aobunazan bypass ˼ which detours the Oirase Stream has been safely industrialized from 2013.

Although trials of private vehicle traffic restriction aimed at the conservation of nature and traffic congestion has so far been tackled by the Oirase Towada Utilization Council, measures have developed monitoring entrance regulations of full scale vehicles and continuing annual trials regulating vehicle types. Thank you for your understanding and cooperation.
