Naruhito is Emperor of Japan. He acceded to the Chrysanthemum Throne on 1 May 2019, beginning the Reiwa era, following the abdication of his father, Akihito. He is the 126th monarch according to Japan's traditional order of succession.
Naruhito was born in Tokyo during the reign of his grandfather Hirohito as the eldest child of Crown Prince Akihito and Crown Princess Michiko. Emperor Hirohito died in 1989, at which point Akihito became emperor and Naruhito became the heir apparent. Naruhito was formally invested as crown prince in 1991. He attended Gakushūin schools in Tokyo and later studied history at Gakushuin University and English at Merton College, Oxford. In 1993, he married Harvard graduate and diplomat Masako Owada. They have one daughter, Aiko, Princess Toshi.
Continuing his grandfather's and father's boycott over the enshrinement of convicted war criminals, Naruhito has never visited Yasukuni Shrine. He is interested in water policy and water conservation and likes to play the viola. He was an honorary president of the 2020 Summer Olympics and 2020 Summer Paralympics and is a supporter of the World Organization of the Scout Movement.
Before becoming emperor, Naruhito was generally referred in the Japanese press by his given name and princely title. Upon succeeding to the throne, he is no longer referred to by his given name, but as "His Majesty the Emperor", which may be shortened to "His Majesty". In writing, the Emperor is also referred to formally as "The Reigning Emperor". The era of Naruhito's reign bears the name "Reiwa" ɾeːwa, and according to custom he will be renamed Emperor Reiwa by order of the Cabinet after his death.
The name of the next era under his successor will be established after his death or before his abdication.
Naruhito was born on 23 February 1960 at 4:15 p.m. in the Imperial Household Agency Hospital in Tokyo Imperial Palace. As a prince, he later quipped, "I was born in a barn inside the moat". His parents, Akihito and Michiko, were then crown prince and crown princess of Japan, while his paternal grandfather, Emperor Shōwa, reigned as emperor.
