Why do cars drive on the left in Japan?

If Japan had ever been part of the British Empire it would be obvious why they adopted the practice of driving on the left. But they’ve never been invaded or conquered by anyone, and the only country they’ve ever surrendered to—the United States—drives on the right. So…why?

Kabuki actor Ichikawa Danzō III demonstrates

Wearing a sword was a major privilege, and even touching another samurai’s weapon was grounds for a duel. An accidental brush was generally waved off as no harm no foul, but if there was bad blood between two clans, one or both warriors were well within their rights to use that as an excuse to fight, and someone could end up dead.

Unfortunately, roads were narrow, and if they passed each other on the right…vendetta unlocked!

So it was decreed that everyone keep to the left, whether riding or walking, so everyone could live to fight another day.

And because modern roads were built on top of ancient tracks like the Old Tokaido Road and the Nakasendo, taking advantage of existing bridges, exits and signs that were all oriented toward people who kept to the left, the custom continued.

So if you’re coming to Japan from a country where they drive on the right, be prepared for Opposite Land if you’re thinking about renting a car or riding a bike!
