Akito Arima, KBE (有馬 朗人, Arima Akito, 13 September 1930 – 7 December 2020) was a Japanese nuclear physicist and politician, known for the interacting boson model.[1][2][3][4]

Early life and career

Arima was born 1930 in Osaka . He studied at the University of Tokyo, where he received his doctorate in 1958. He became a research associate at the Institute for Nuclear Studies in 1956.

Arima became a lecturer in 1960, and an associate professor at the Department of Physics in 1964 at the University of Tokyo. He was promoted to a full professor in 1975. He was president of the University of Tokyo during 1989–1993. In 1993, he moved to Hosei University. Since 1993, he has been scientific adviser of the Ministry of Education and from 1993 to 1998 president of RIKEN.[5][6]

He was a visiting professor at Rutgers University, New Jersey (1967–1968), and a professor at the State University of New York at Stony Brook (1971–1973). In 1974, he founded the interacting boson model with Francesco Iachello.

In 1998 he entered the Diet of Japan as a member of the House of Councillors for the Liberal Democratic Party. He was Minister of Education until 1999 under the government of Keizo Obuchi. After the cabinet reshuffle in 1999, he served as Director of the Science Museum. From 2000 he was chairman of the Japan Science Foundation.

Arima has served as the Chancellor of Musashi Academy of the Nezu Foundation since 2006.[7][8]


Arima died from heart failure on December 7, 2020, at the age of 90.[9] On the day of his death, he will be conferred the rank of Shosanmi.[citation needed]
