# Japan residential road speed limit reduction > Live situation record from CLSTR: https://clstr.news/situations/japan-residential-road-speed-limit-reduction > Updated: 2026-09-02T02:08:15.000Z. Sources: 33. Developments: 4. As of September 1, 2026, Japan has implemented amendments to the Road Traffic Act, reducing the statutory speed limit on residential “living roads” from 60 km/h to 30 km/h. These roads are defined as paths used for daily life that lack center lines or median strips, a category that accounts for approximately 70 percent of general roads across the country, totaling roughly 870,000 kilometers. 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. While general accident rates have declined, fatalities among these vulnerable groups on residential roads have remained steady at approximately 300 per year. The initiative aims to decrease these fatalities, as data indicates the risk of death increases sharply when vehicle speeds exceed 30 km/h; specifically, the mortality rate for pedestrians is less than 1 percent at or below 30 km/h, compared to 17.4 percent at speeds between 50 and 60 km/h. The new limit applies to motorcycles, though the statutory limit for mopeds remains unchanged at 30 km/h. Certain road types will not be affected, including expressways, motor-vehicle-only roads, and general roads equipped with center lines or vehicle lanes. In all cases, if a specific maximum speed is indicated by road signs or markings, that designated speed will take precedence. Following implementation, local authorities have launched public awareness campaigns. However, surveys indicate ongoing driver uncertainty regarding the specific criteria for these residential roads, highlighting challenges in communicating how to identify which paths are subject to the new limit. ## Claims - The statutory speed limit for automobiles on residential roads will be reduced from 60 km/h to 30 km/h.
