Japan halves speed limit to 30km/h on all narrow city streets

Japan reduced the speed limit from 60km/h to 30km/h on 870,000km of narrow residential roads lacking center lines. This policy targets 70% of the nation's general roads to protect pedestrians, as mortality rates jump from under 1% at 30km/h to 17.4% at 60km/h. The measure addresses persistent accident rates involving children and the elderly.
