Japan National Route 12, National highway in Hokkaido, Japan
Japan National Route 12 is a national highway spanning about 145 kilometers between Sapporo and Asahikawa, passing through several cities including Ebetsu, Iwamizawa, and Fukagawa. The road runs parallel to the tolled Dō-Ō Expressway, offering drivers a free alternative for travel between Hokkaido's two major urban centers.
The Kamikawa Road, the predecessor of this route, was built starting in April 1886 using prison labor from political detainees to create an 88-kilometer connection between Mikasa and Asahikawa. This original pathway eventually became the foundation for the modern national highway that now links Hokkaido's interior regions.
The route functions as a central artery through Hokkaido, connecting communities and supporting the transportation of agricultural products between different regions.
The road is well served by public buses and accessible by private vehicles with rest stops and fuel stations throughout its length. Drivers should prepare for snow and slippery conditions during winter months, which are typical for Hokkaido's climate.
Between Bibai and Takikawa lies a straight road section stretching about 28 kilometers, one of Japan's longest uninterrupted straight stretches. This remarkably long straightaway offers extended sightlines and creates a distinctive driving experience.
