Japan reduces residential road speed limit to 30 km/h

Japan has implemented a nationwide reduction in the statutory speed limit for residential roads, lowering it from 60 km/h to 30 km/h. The amendment, which took effect on September 1, 2026, targets narrow streets—approximately 870,000 kilometers of road—that lack center lines, median strips, or specific speed limit signage. These roads account for roughly 70% of the country's general road network.

The measure aims to protect pedestrians, particularly children and the elderly, by reducing the severity of accidents. National Police Agency data indicates that the mortality rate for pedestrians is less than 1% when vehicles travel at or below 30 km/h, compared to 17.4% at speeds between 50 and 60 km/h. While overall traffic fatalities in Japan have reached record lows, accidents involving vulnerable groups in residential areas have remained a concern.

Authorities and local police departments are conducting awareness campaigns to help drivers identify which roads are subject to the new limit. Surveys indicate some driver uncertainty regarding the specific criteria for these residential roads, emphasizing the need for continued public information.
