Japan’s traffic rules have changed! Default speed limit on residential roads reduced to 30 km/h
If you’re visiting Okinawa and planning to rent a car, please take note! ⚠️
On September 1, 2026, Japan’s amended Road Traffic Act Enforcement Order came into effect, lowering the default speed limit on residential roads from 60 km/h to 30 km/h.
If you’re unfamiliar with the new rule, you could exceed the speed limit without realizing it.
📢 On residential roads without a center line or other separation between opposing traffic, the default speed limit for motor vehicles has been reduced from 60 km/h to 30 km/h.
💡 What are “residential roads”?
・Roads without a center line or other separation between opposing traffic
・Relatively narrow roads mainly used by local residents
💡 What does this mean for travelers using rental cars?
・On roads without a posted speed limit, the default limit may now be 30 km/h instead of 60 km/h
・Depending on how far the speed limit is exceeded and the circumstances of any resulting accident, drivers may face criminal charges
💡 What about other roads?
・On general roads with a center line, designated traffic lanes, or a physical barrier separating opposing traffic, the default speed limit generally remains 60 km/h
・If a speed limit is indicated by a road sign or road marking, always follow the posted limit
・On Okinawa’s expressways, the speed limit is 80 km/h throughout
📌 Remember these points when driving in Okinawa!
・Check Japan’s traffic rules before driving
