Atsuko Ikeda

Atsuko Ikeda , formerly Atsuko, Princess Yori , is the fourth daughter of Emperor Shōwa and Empress Kōjun. As such, she is the older sister of Emperor Emeritus Akihito and paternal aunt of Emperor Naruhito. She married Takamasa Ikeda, a man from outside the imperial dynasty, on 10 October 1952; as a result, she gave up her imperial title and left the Japanese imperial family, as required by law. Later, she served as the supreme priestess (saishu) of the Ise Grand Shrine between 1988 and 2017.
