Who is Emperor Naruhito?
Born on 23 February 1960, Emperor Naruhito is the current Emperor of Japan and the oldest child of Emperor Akihito and Empress Michiko. He became heir apparent to the Chrysanthemum Throne when he was 29 following the death of his grandfather, Emperor Shōwa.
At the age of four, Naruhito was enrolled in an elite Japanese school, graduating in 1982 with a degree in history; the ruler credited his fascination with the subject to his discovery of an ancient roadway on palace grounds during his youth. He later studied at Oxford and went on to meet many members of European royal families. During a party for Spain's Infanta Elena in 1986, he met Masako Owada.
Meet Empress Masako
Born as Masako Owada on 9 December 1963, Masako became the Empress of Japan due to her marriage to Emperor Naruhito, who ascended the throne in 2019. Masako was born to a senior diplomat and former president of the International Court of Justice and was mostly raised in Moscow and New York City.
After her education, Masako started working at the Japanese Ministry of Foreign Affairs, being one of only 28 of 800 applicants to pass the entrance exams. At a party for Spain's Infanta Elena in November 1986, she met Prince Naruhito before their marriage in 1993. Masako sadly suffered a miscarriage in 1999, before giving birth to daughter Aiko in 2001.
