Driving in Japan can be a fantastic way to explore the country, but it’s important to be familiar with the road signs and traffic laws to ensure a safe and smooth journey. Whether you’re planning a road trip or just navigating around town, understanding these rules is key. Here’s what you need to know about Japanese road signs and traffic laws before hitting the road.

1. Japanese Road Signs

Japanese road signs may look different from what you’re used to, but they follow international standards and are generally easy to understand once you’re familiar with the basics. Here are some common road signs:

• Circle with a red border: This usually means prohibition, such as “No Entry” or “No U-turn.”
• Blue circles: Indicate directions or permissions, like “One-way” or “Turn left.”
• Yellow diamonds: These are used for warnings, like “Slippery road” or “Pedestrian crossing.”
• Arrow signs: Indicate the direction of traffic flow or the appropriate lanes to use.
• Speed limit signs: Common speed limits in cities are 40 km/h, and on highways, it is generally 100 km/h unless specified otherwise.

While most signs have kanji (Japanese characters), they also use international symbols that are universally recognizable, making them easier to understand even if you’re not fluent in Japanese.

2. Driving on the Left Side of the Road

In Japan, driving is on the left side of the road, unlike in many countries where it’s on the right. The steering wheel is on the right side of the car, and this is important to remember when navigating intersections and roundabouts. If you’re used to driving on the right side, it may take a little time to adjust.

3. Speed Limits and Enforcement

Speed limits in Japan are strictly enforced. Here are some general guidelines:

• Urban areas: The speed limit is generally 40 km/h unless otherwise posted.
• Rural roads: Speed limits range from 50 km/h to 60 km/h.
• Highways: The speed limit is usually 100 km/h, but in some areas, it could be 80 km/h.
• School zones: Speed limits in school zones can be as low as 30 km/h during school hours.

Speeding fines in Japan can be hefty, and enforcement is strict, so always adhere to posted speed limits.

4. Drink Driving Laws

Japan has a zero-tolerance policy for driving under the influence of alcohol. The legal blood alcohol concentration (BAC) limit is 0.03%, which is much lower than in many other countries. Police frequently conduct random breathalyzer checks, and if you are caught driving over the limit, you could face heavy fines, license suspension, or even jail time. Don’t drink and drive in Japan — it’s simply not worth the risk.

5. Parking Rules

Parking in Japan can be tricky, especially in urban areas, as spaces are limited and can be quite expensive. Make sure to park only in designated areas:

• No parking zones: These are marked with signs and can result in fines or towing if violated.
• Private parking lots: Use only parking lots that are clearly marked, and be prepared to pay the fee.
• Street parking: In some areas, street parking is allowed, but there are often restrictions, so check the signs for any time limits or conditions.

Illegal parking can result in hefty fines, and in extreme cases, your car may be towed.

6. Use of Seat Belts

Wearing seat belts is mandatory for all passengers in the car, both in the front and back seats. Police may stop you if they see anyone not wearing a seat belt, and fines for not complying are applied. This is a strict law to ensure the safety of everyone in the vehicle.

7. Traffic Lights and Intersections

Japanese traffic lights generally follow the standard red, yellow, and green sequence, but be aware of a few differences:

• Flashing yellow lights: A flashing yellow light means “proceed with caution”. This usually indicates that you’re approaching an intersection or pedestrian crossing where you should slow down.
• Left turns: In Japan, left turns are allowed on red lights unless otherwise specified by a sign. But be cautious, as some intersections do not permit left turns on red.
• Pedestrian crossings: Always stop for pedestrians at crosswalks — they have the right of way.

8. Toll Roads

Japan has an extensive system of toll roads (expressways), which are generally in excellent condition. Be prepared to pay tolls when using the highways. Most toll booths accept ETC cards (Electronic Toll Collection), but cash payments are also possible. If you’re planning on using the expressways a lot, consider renting an ETC card with your rental car.

9. Emergency Vehicles and Hazard Lights

When you see emergency vehicles (ambulances, police cars, or fire trucks) with sirens on, you must pull over to the left to give them the right of way. Also, using hazard lights while driving is illegal unless you are in an emergency or stopped due to an issue with your vehicle.

10. Road Safety and Etiquette

Japanese drivers are known for their courteousness and careful driving. Honking your horn in Japan is considered impolite and should only be used in emergencies. Always be considerate of other drivers, especially when changing lanes or merging.
