In feudal Japan during the shogunate era, samurai typically carried their swords on the left side of their bodies and fought with their right hands, which to the habit of walking on the left side of the road. After the Meiji Restoration, Japan adopted traffic regulations from Britain, thus also driving on the left. This rule was formally established by law in 1924. Here is additional information: British driving rules: The British had a custom of keeping to the left, but there were no strict regulations before the victory of the British bourgeois revolution. After the victory and before the first industrial revolution, due to the prosperity of commerce, a preliminary transportation network had formed in Britain. The upper class often traveled by carriage, and if they drove on the left, the coachman's whip could easily injure pedestrians.

Japan's left-hand traffic system is quite interesting. I've thought about it for a long time and found it's mainly a historical legacy. During the Meiji Restoration, Japan underwent nationwide reforms, and the British helped build the railway system. Since Britain already drove on the left, Japan followed suit. Another reason is related to samurai traditions. In ancient times, samurai walked on the left side with their sword scabbards hanging on the right side of their waists to avoid bumping into others or preventing fights. These habits became integrated into traffic rules and have continued ever since. Today, left-hand driving is practiced in places like the UK and Australia, which facilitates trade and tourism. Japan hasn't changed it because switching sides would be too costly and cause chaos. In short, it's a mix of history and culture, and the habit has become second nature.

About why Japan drives on the left, I've been driving for decades and still often discuss this. The key point lies in the Meiji era when Japan was learning from the West, and British rules prevailed—both railways and cars drove on the left. It's also related to the samurai era; they walked on the left side of the street so their sword scabbards wouldn't scrape against passersby, which evolved into a traffic habit. This rule makes roads safer, as everyone follows the same direction, reducing accidents. Globally, Japan aligns with countries like the UK, avoiding the hassle of international driver's licenses. I've also noticed that left-side driving makes traffic flow smoother. Nowadays, Japanese highways are designed this way, making any change difficult due to the massive impact. So, it's a mix of old tradition and practical benefits.

Japan's left-hand traffic is actually quite simple, mainly due to historical reasons. During the Meiji period, Japan adopted the British traffic system, including driving on the left. Samurai also traditionally walked on the left to avoid collisions, and this practice gradually became standard. Today, maintaining uniformity with countries like the UK makes it convenient for international visitors. I was curious and researched it myself, and I think it's a good system that reduces the risk of accidents. Over time, this custom has contributed to social harmony, so there's no need to change it.

I need to explain the origin of Japan's left-hand traffic, which stems from the Meiji Restoration. During that period, Japan underwent comprehensive modernization and adopted the British model, making left-hand traffic for railways and automobiles the standard. Samurai culture also contributed to this practice, as walking on the left was a custom to prevent conflicts. Today, it not only simplifies matters but also aligns with many countries worldwide, such as India, facilitating economic exchange. In my studies, I've observed that this rule stabilizes the transportation system, enhances safety, and once people adapt, it becomes firmly established.

As someone who frequently visits Japan, I've noticed that all vehicles drive on the left. After some research, I found that during the Meiji era, British influence was significant, and traffic rules followed the British left-side driving. The samurai tradition also played a role, as walking on the left allowed for wider passage. This practice continues today, with the benefit of vehicle compatibility within the British trade zone, making it easier for me to adapt using an international driver's license. Once accustomed, the road organization feels well-structured, reducing confusion. In the long run, a combination of history and practicality has kept this system unchanged.
