Yasunori Mitsuda (光田 康典 Mitsuda Yasunori?, born January 21, 1972) is a Japanese video game composer, sound programmer, and musician. He has composed music for or worked on over 35 games, and has contributed to over 15 other albums. He is best known for his compositions for the video games Chrono Trigger, Chrono Cross, Shadow Hearts, Shadow Hearts: Covenant, Xenogears, Xenosaga Episode I, and Mario Party. He began composing video game music for his own games in high school, and after graduation attended Junior College of Music in Tokyo. In 1992 upon graduation he joined Square (now Square Enix) as a composer after seeing a magazine advertisement in an office he was visiting with his professor.
Despite his job title as a composer, Mitsuda worked for two years as a sound engineer. In 1994, after threatening to quit to Square's vice president, Hironobu Sakaguchi, he was assigned to compose the soundtrack to Chrono Trigger. After the game's success and the music's acclaim, he went on to compose several other games for Square, including Xenogears. In 1998 Mitsuda left Square to work as a freelance composer, founding his own music production studio, Procyon Studio, in 2001 as well as his own record label, Sleigh Bells. The company has since expanded to nine employees, and Mitsuda continues to compose for video games, as well as for anime series and his own independent albums.
