Japan Slashes City Speed Limits to 30km/h
2 Sep
Summary
- Speed limit reduced from 60km/h to 30km/h on narrow urban roads.
- New limit targets roads less than 5.5 metres wide without centre lines.
- Authorities aim to reduce pedestrian accidents involving children and elderly.
Drivers in Japan are now required to adhere to a reduced speed limit of 30km/h on many residential roads. This significant cut from the previous 60km/h limit is intended to enhance safety on narrow urban streets, which often lack centre lines and pavements.
The new regulations apply to approximately 870,000 kilometers of roads that are less than 5.5 meters wide. These roads represent about 70% of Japan's general road network and pose a higher risk to pedestrians, especially children and older individuals.
Despite an overall decline in traffic accident fatalities, those involving children and the elderly on residential roads have remained a concern. Data from 2025 indicated a rise in these specific accidents for the first time in three years. Previous "zone 30" initiatives, introduced in 2011 on limited streets, demonstrated a 30% reduction in fatalities and serious injuries.
Police data highlights the critical impact of speed on pedestrian survival rates. The mortality rate is less than 1% for accidents below 30km/h, increasing significantly at higher speeds. Authorities urge drivers to exercise extreme caution on roads shared with pedestrians and cyclists.
