The Current Emperor of Japan (今上天皇) is Akihito. He was officially enthroned on November 12, 1990. He is styled as "His Imperial Majesty" (天皇陛下), and his reign bears the era name of Heisei (平成). Naruhito, the Crown Prince of Japan, is the heir apparent to the Chrysanthemum Throne.
Ise Grand Shrine
During the Empire of Japan and the establishment of State Shinto, the position of chief priest of the Ise Shrine was fulfilled by the reigning emperor and the Meiji, Taisho and Shōwa Emperors all played the role of chief priest during their reigns.
Since the disestablishment of State Shinto during the Occupation of Japan, the offices of chief priest and most sacred priestess have been held by former members of the imperial family or their descendants. The current chief priest of the shrine is Takatsukasa Naotake, adoptive son of Takatsukasa Kazuko. He succeeded Kitashirakawa Michihisa, a great-grandson of the Meiji Emperor, in 2007. Kitashirakawa Michihisa succeeded his cousin Kuni Kuniaki, the eldest son of former Prince Kuni Asaakira (brother of Empress Kōjun), in 2001. Kitashirakawa's grandmother, Kitashirakawa Fusako, the seventh daughter of the Meiji Emperor, served as most sacred priestess of the Ise Shrine from 1947 until her death in 1974. She was succeeded in that post by Takatsukasa Kazuko, third daughter of the Emperor Shōwa, who held the post until ill health forced her retirement in 1988. Takatsukasa Kazuko was succeeded by her younger sister, Ikeda Atsuko. In 2012, Ikeda was joined by her niece Kuroda Sayako, sole daughter of reigning Emperor Akihito, to serve as a high priestess under her. On 19 June 2017, Kuroda officially replaced her aunt as supreme priestess.
