Graduated from Kunitachi Music College.
He has won the Japanese equivalent of the Academy Award for Best Music seven times.
His name came from Quincy Jones. The kanji for "Hisaishi" could be read as "Kuishi," which is close to the Japanese pronunciation of "Quincy," which, however, would be pronounced "Kuinshî," and "Joe," of course, came from "Jones." Hisaishi chose this name himself when he needed a stage name.
He has scored the highest grossing domestic film in both Japan (Spirited Away (2001)) and China (Let the Bullets Fly (2010)).
