A major accident occurred on the Kanetsu Expressway in Japan, resulting in 20 vehicles catching fire. The incident was reportedly initiated by a sudden interruption in traffic flow. As a result, numerous cars collided and quickly ignited, causing a substantial fire. Emergency services were immediately dispatched to manage the situation and aid the involved parties.

Traffic accidents and highway safety are of great concern in Japan, boasting one of the most heavily utilized road networks in the world. The public expects thorough investigations, strict application of laws, and efficient emergency responses whenever such instances occur.

Similar to the US or EU, Japan has firm laws about road safety, traffic management, and accident investigations. However, Japan often stands out for its efficient and immediate response from emergency services and the public's general respect for safety rules and regulations.
