Japan follows the left-hand traffic rule. The practice of driving on the left in Japan dates back to the Edo period. During the Edo era, many roads in Japan were narrow, making it difficult for samurai to pass through easily. Additionally, most samurai carried their swords on their left waist. If they walked on the right side, their swords would clash with oncoming pedestrians when passing by, which gradually led to the adoption of left-hand traffic. Other countries that drive on the left include: The United Kingdom, Ireland, Australia, New Zealand, India, Indonesia, Pakistan, Thailand, South Africa, Sri Lanka, Malta, Papua New Guinea, Fiji, Tonga, Nauru, Jamaica, Malaysia, Singapore, South Africa, The Gambia, Sierra Leone, Ghana, Nigeria, The Bahamas, the Cayman Islands, the Turks and Caicos Islands, the British Virgin Islands, and others, primarily Commonwealth countries. Originally, the driver's seat in cars was positioned in the center of the vehicle. Soon after, some automakers placed the driver's seat on the side closer to the center of the road to better observe oncoming traffic, while others placed it on the side closer to the roadside to avoid collisions with obstacles like walls, hedges, or ditches. Practical experience showed that the former approach was more conducive to road safety, which became the standard for automakers. This led to the distinction between left-hand drive (driver's seat on the left front) and right-hand drive (driver's seat on the right front) vehicles. The side of the road on which vehicles drive depends on the long-standing traffic rules of each country, resulting in more detailed and strict road traffic regulations. Many countries have legally defined the direction of vehicle traffic.

As someone who frequently shares automotive knowledge, I can confidently say that Japan is a strict left-hand traffic country, with the steering wheel on the right side, similar to the UK and Australia. This originated from British influence in the 19th century when the Meiji government introduced Western traffic systems and adopted left-hand traffic rules. Left-hand driving may be safer because most people are right-hand dominant, making it more convenient for drivers to operate the gearshift with their right hand. If you plan to drive in Japan, be sure to rent a vehicle with a right-hand steering wheel and remember to keep to the left side of the lane. When crossing the street, look right first and then left. Overall, Japan's road traffic is highly efficient, with clear road signs and a low accident rate. I recommend reading some driving guides before your trip to familiarize yourself with the rules.

I just came back from a self-guided trip to Tokyo, and during my self-driving experience, I personally experienced Japan's left-hand traffic, which is completely different from the right-hand traffic in the US. At first, I kept wanting to turn right when making turns, but thankfully the navigation reminded me, so no accidents happened. The steering wheel being on the right made shifting gears and overtaking a bit awkward, but the Japanese drive very orderly, and left-hand traffic makes the flow smoother. Even the habit of crossing the street changed: pedestrians need to look right then left, the opposite order. Car rental companies usually provide instruction booklets, and I recommend renting a compact car for easier handling. This habit also affects the design of bike lanes and subway systems, so remember to adjust your mindset in advance and enjoy a safe journey.

I recently looked up information and confirmed that Japan indeed drives on the left side, with the driver's seat on the right. When traveling there, don't get it wrong - always keep to the left lane. When crossing the street, pay attention to the right-left direction. Once you get used to it, it becomes quite smooth. Japan's road network is meticulously designed for left-side driving, with optimizations like mirror positioning. Beginners might easily get confused, so choosing an automatic transmission when renting a car can reduce trouble.

From a safe driving perspective, Japan's left-hand traffic system indeed enhances overall road safety. With the driver seated on the right side, it's easier to judge turning distances and overtaking gaps, reducing blind spot accident risks. Traffic regulations emphasize left-side driving: for instance, left turns have priority at traffic lights, and pedestrian crossings start from the right. Tourists driving should gradually adapt to avoid accidentally entering the right lane when starting, which could cause accidents. Road designs also accommodate left-hand traffic: bridge dividers and tunnel markings are all biased toward the left. It's recommended to use driving simulation apps to familiarize yourself with the rules beforehand.

The historical roots of left-hand traffic in Japan run deep, inherited from Britain during the Meiji Restoration in the 19th century, forming a unique driving culture. Compared to right-hand traffic in Europe and America, Japan's left-hand driving emphasizes order: walking on the left, left-turning vehicles having priority, which also extends to cycling and queuing habits. Driving with the steering wheel on the right takes time to adapt to, but once accustomed, you'll appreciate its efficiency. Travelers are advised to observe local behaviors when walking or renting a car to ensure safe integration into the local environment.
