A major traffic incident struck the Sanyo Expressway in Japan, causing several vehicles to stack up and block the roadway. The incident not only halted traffic but also limited access for emergency services. As of now, the cause of the congestion is still being scrutinized by the authorities who are working round the clock to ensure smooth vehicular movement. The event triggered notable disruption to the daily lives of commuters and local population.

In Japan, minor traffic accidents can often lead to significant delays due to the country's strict regulations for handling collisions. Even non-injury accidents often mean all involved vehicles need to stop, gather evidence and wait for police to arrive. This can cause lengthy traffic jams and major disruptions, especially on busy expressways.

Unlike in the US or EU, where minor accidents tend to be resolved by individuals sharing insurance details and, if necessary, moving their vehicles off the road to prevent congestion, the process in Japan is significantly more procedure-oriented. Although this system is rigorous and ensures a fair outcome for all involved, it can result in substantial delays.
