Heisei (平成) is the current era in Japan. The Heisei era started on 8 January 1989, the first day after the death of the reigning Emperor, Hirohito. His son, Akihito, succeeded to the throne. In accordance with Japanese customs, Hirohito was posthumously renamed "Emperor Shōwa" on 31 January.
Thus 1989 corresponds to Shōwa 64 up to 7 January and to Heisei 1 (平成元年 Heisei gannen, gannen means "first year") since 8 January.
