　Strong cold air will flow in from the night of December 12 (Sun) to the day of December 14 (Tue), and it is expected that the area around Japan will have a strong winter-type pressure distribution. Due to this effect, there is a risk of heavy snowfall, especially on the Sea of Japan side of northern Japan and eastern Japan.
If even one vehicle that cannot run on its own occurs on the Expressway, it may lead to long-term traffic jams or road closures. When using the Expressway, be sure to wear winter tires and carry tire chains, and check the latest weather forecast and road information.

Driving on snowy roads with normal tires is against the law. ]
