List of emperors of Japan facts for kids

Kids Encyclopedia Facts

Japan has been ruled by emperors since ancient times. The earliest emperors and their dates are mostly known from an 8th-century book called Nihon Shoki. This book was written to make the Yamato dynasty seem older and more important, claiming it started in 660 BCE. Historians aren't sure who the very first Japanese ruler was. Some believe it might have been Emperor Yūryaku (who ruled from 456–479) or Emperor Kinmei (who ruled from 539–571), among others.

The titles Tennō (meaning 'Emperor') and Nihon (meaning 'Japan') were first used in the late 600s CE. Japan uses a special calendar system called nengō. In this system, years are counted from the start of a new era, which usually begins when a new emperor takes the throne. This system has been used since the late 600s.
