日本第一長的直線道路 / The longest straight road in Japan

從國道12線上的美唄市到滝川市的區間有日本第一長的直線道路。全長為29.2公里，在道路兩端上的位置設有告知看板。此外，位於奈井江町的「道路休息站」，有位於中間地點的奈井江町的指示看板。希望租車旅遊的觀光客能感受到如同這般很有北海道感覺的觀光景點。

The stretch of Route 12 between Bibai City and Takikawa City, is the longest straight road in Japan. It's 29.2 kilometers in length, and there are tall signs at the start / end points. As the middle point is in Naie Town, there is also a tall sign to inform that drivers have passed the middle point. For those who are traveling around Hokkaido by rental car, this experience could give a good memory of driving on the Japan's longest straight road. That might give travelers the feeling they are enjoying their own adventure in Hokkaido. Naie Town is 72 kilometers away from Sapporo.
