Akihito

Born in 1933, Akihito is the fifth child and first son of Emperor Shōwa and Empress Kōjun. During the Second World War, he moved out of Tokyo with his classmates and remained in Nikkō until 1945. In 1952, his Coming-of-Age ceremony and investiture as crown prince were held, and he began to undertake official duties in his capacity as crown prince.^[2] The next year, he made his first journey overseas and represented Japan at the coronation of Elizabeth II, queen of the United Kingdom and Commonwealth. He completed his university education in 1956. In April 1959, he married Michiko Shōda, a commoner; it was the first imperial wedding to be televised in Japan, drawing about 15 million viewers.^[3] The couple has three children: Naruhito, Fumihito, and Sayako.


When his father died in January 1989, Akihito succeeded to the Chrysanthemum Throne and became emperor of Japan, with an enthronement ceremony in 1990. He made efforts to bring the imperial family closer to the Japanese people, and made official visits to all forty-seven prefectures of Japan and to many of the remote islands of Japan. He has a keen interest in natural life and conservation, as well as Japanese and world history.^[2] Akihito abdicated in 2019, citing his advanced age and declining health,^[4] and assumed the title Emperor Emeritus (上皇, Jōkō, lit. 'Retired Emperor'). He was succeeded by his eldest son, Naruhito, whose era is named Reiwa (令和). At age 90, Akihito is the longest-lived verifiable Japanese emperor in recorded history. During his reign, 17 prime ministers served in 25 terms, beginning with Noboru Takeshita and ending with Shinzo Abe.

In extension of his father's interest in marine biology, who published taxonomic works on the Hydrozoa, the Emperor Emeritus is a published ichthyological researcher, and has specialized in studies within the taxonomy of the family Gobiidae.^[43] He has written papers for scholarly journals such as Gene, Ichthyological Research, and the Japanese Journal of Ichthyology.^[44][45] He has also written papers about the history of science during the Edo and Meiji eras, which were published in Science^[46] and Nature.^[47] In 2005, a newly described goby was named Exyrias akihito in his honour, and in 2007 a genus Akihito of gobies native to Vanuatu also received his name. In 2021, the Imperial Household Agency announced Akihito had discovered two new species of goby fish. The discovery was catalogued in an English-language journal published by the Ichthyological Society of Japan.^[48][49]


In 1965, then-Crown Prince Akihito sent 50 Nile tilapia to Thai King Bhumibol Adulyadej in response to a request for fish that could solve malnutrition issues in the country. The species has since become a major food source in Thailand and a major export.^[50]
