Japan has left-hand side traffic.

The statement "Japan has left-hand side traffic" is true. In Japan, traffic follows a left-hand driving system, which means vehicles drive on the left side of the road. This practice began during the Edo period (1603-1868) when samurais used to walk on the left side of the road to protect themselves from potential ambushes. This tradition continued over time, and even after the introduction of automobiles, Japan held onto left-hand driving. It is important to note that Japan is not the only country with left-hand traffic, as there are several others around the world, including the United Kingdom, Australia, and India.
