Japan lowers residential road speed limit to 30 km/h

speed limit reduction residential roads traffic safety National Police Agency road traffic laws

Starting September 1, 2026, Japan will implement a significant change to its traffic regulations by lowering the statutory speed limit on residential roads from 60 km/h to 30 km/h. This measure specifically targets roads that lack center lines, median strips, or designated maximum speed signs, which account for approximately 70% of ordinary roads nationwide.

The National Police Agency introduced this revision to reduce traffic accidents in urban areas and narrow streets where pedestrians, children, and the elderly are frequently present. Data indicates that despite a general decline in accidents, fatalities among these vulnerable groups on residential roads have remained steady at around 300 per year. The reduction aims to mitigate the high risk of fatal injuries that occurs when vehicle speeds exceed 30 km/h.

Drivers are advised that the 30 km/h limit applies to roads without specific markings or signs. On major roads with multiple lanes, center lines, or existing speed limit signs (such as 40 km/h), the previous or designated limits will remain in effect. Law enforcement agencies across various regions, including Kanazawa and Kobe, have begun public awareness campaigns to ensure motorists understand the new rules and the importance of cautious driving in residential areas.
