History of Emperor’s Birthday
The tradition of celebrating the emperor’s birthday dates back to ancient times but became a formal public holiday during the Meiji Era (1868–1912). Originally called Tenchosetsu (meaning “The sky and earth are eternal”), it symbolized hope for the emperor’s everlasting reign. After World War II, the holiday was renamed Tennō Tanjōbi to reflect a more modern and symbolic monarchy. Each emperor’s birthday marks a new chapter in this ongoing tradition.
