Sushi, a dish made with vinegared rice and various fillings such as raw fish or vegetables, is one of the most famous Japanese foods and has become popular around the world.

The Showa period, which lasted from 1926 to 1989, was marked by Japan's militarism and involvement in World War II.

Japan's recorded history dates back to the 5th century AD, when the first known emperor, Emperor Jimmu, ascended to the throne.
