Hosoya, Haruo was born on July 18, 1936 in Kamakura, Kanagawa, Japan. Son of Tomiji and Hatsui (Arakawa) Hosoya.
During 1955-1959 he studied at the University of Tokyo. In 1964 he wrote his Doctor of Philosophy thesis, "Study on the Structure of Reactive Intermediates and Reaction Mechanism".
After retirement he keeps working in computational chemistry. In 1971, Hosoya defined topological index (a graph invariant) as the total number of matchings of a graph plus 1. The Hosoya index is often used in computer (mathematical) chemistry investigations for organic compounds.
In 2002-2003 the Internet Electronic Journal of Molecular Design dedicated a series of issues to commemorate the 65th birthday of professor Hosoya.
Member of Society Committee Chemical Japan (president since 2003), Chemical Software Society of Japan (vice president 1992-1995, president 1996—2002), International Society for Mathematics Chemistry (board directors), Chemical Society of Japan 1976-1978, (editor Chemistry and Education 1992-1994, vice president 1996-1998, chairman council chemical education 2001-2004).
