Driving in Japan is a unique experience that demands strict discipline and a deep respect for local laws. To ensure a safe trip, you must prioritize these critical regulations.

The Fundamentals: Left-Side Driving

The most immediate change for many is that traffic moves on the left. This means the driver’s seat and controls are on the right.

  • Turning on Red: This is strictly illegal. You must wait for a green light or a green arrow to turn.
  • Railway Crossings: You are legally required to come to a full stop before any train tracks, regardless of whether a train is approaching.

Zero Tolerance for Alcohol

Japan enforces a zero-tolerance policy for driving under the influence. The legal limit is effectively $0.00\%$.

  • Passengers Beware: In Japan, passengers can also be fined or arrested if they knowingly ride with a driver who has consumed alcohol.

Critical Signs and Speed

  • The Stop Sign: Look for an inverted red triangle with the text “止まれ” (Tomare). You must come to a complete halt behind the line.
  • Speed Limits: Generally low. Urban zones are usually 30–50 km/h, while expressways range from 80–100 km/h.
  • Pedestrians: They always have the absolute right of way. Drivers must be extremely cautious at all crosswalks.

Legal Requirements

You cannot drive with a standard foreign license alone. You must carry a valid International Driving Permit (IDP) issued under the 1949 Geneva Convention, along with your original license and passport.

Pro Tip: It is customary to flash your hazard lights briefly as a “thank you” to other drivers when they let you merge.
