Quick Summary

The Japanese government has implemented a speed limit of 30km/h on all narrow city streets as part of an effort to reduce deaths and injuries among pedestrians. The new speed limit applies to approximately 870,000 kilometers of roads that are less than 5.5 meters wide and do not have center lines or median strips. According to national police agency data, the number of fatal accidents involving children and older people on residential roads has remained steady at around 300 per year since 2021, despite a overall decline in traffic deaths. The restrictions aim to address concerns that residential areas are not experiencing the same safety improvements as larger roads.

Story summary

Japan has implemented a new speed limit of 30km/h for all narrow city streets, reducing the previous limit from 60km/h. This change applies to about 870,000km of roads that are less than 5.5 meters wide and lack center lines or median strips, which account for around 70% of the country's general roads. The main goal is to reduce deaths and injuries among pedestrians, particularly children and older people, who are at higher risk on narrow urban streets without sidewalks. According to police data, pedestrian mortality rates are significantly lower when vehicles travel at or below 30km/h, compared to speeds between 50-60km/h. The new limit went into effect on Tuesday, in an effort to address concerns that residential areas were not seeing the same safety improvements as larger roads. Japan's overall traffic death toll has decreased, reaching a record low of 2,457 last year, but accidents involving children and older people on residential roads have remained a concern.
