heisei
Heisei (平成, lit. "becoming peaceful" or "peace everywhere") is the official name of the era of Japanese history spanning from 1989 to 2019.
Beginning immediately after the death of Emperor Hirohito and the ascension of Crown Prince Akihito to the Chrysanthemum Throne, the Heisei era followed the Shouwa era (1926-1989), the Taishou era (1912-1926), and the Meiji era (1868-1912). The Heisei ended on May 1, 2019, when Akihito abdicated and his son Naruhito succeeded him as emperor, marking the beginning of the Reiwa.
