Japanese Years

The traditional Japanese calendar is based entirely on the reigns of its emperors. In Japan, AD 1999 is Year "Heisei 11," and this "11" means that it is the eleventh year of the "Heisei" Era, the reign of Emperor Akihito. Though this system is not specifically designated as the "official calendar," it is used by most Japanese people just as commonly as the Gregorian calendar. And under the law, official government documents must be dated with this system. This is the calendar system called Gengo. Telling the year by using an era system was a common tradition of most East-Asian countries. Japan, which had been using the traditional Chinese zodiac system, started using its own Gengo system in 645.

As of the "Meiji" Era, which started in 1868 with the imperial succession of Mutsuhito, each emperor's reign constituted one Gengo: The year an emperor ascends the throne is the first year of a new era, and the era stays the same as long as the emperor reigns. For instance, Hirohito ascended the throne on December 26, 1926, and that day, the new era, "Showa," started; "Showa" lasted for 62 years and two weeks, until his death on January 7, 1989. It was also decided that, after the death of an emperor, he would be referred to by the name of the Gengo he used, not by his own name. So today, Hirohito is known to the Japanese as the Showa Emperor.

The present Gengo, "Heisei," meaning "Achieving Peace," was unveiled only six hours after the death of Hirohito. The new year, "Heisei 1," officially began at midnight, January 8. Therefore, 1989 is regarded as both Year "Showa 64" (the first 7 days) and Year "Heisei 1" (the rest of the year).
