Composer and pianist Yoko Shimomura joined Japanese video game production company Square in 1993 after graduating from Osaka Music School. Prior to her employment with Square, she worked for Capcom, where she composed the majority of the score to the legendary fighting game Street Fighter II: The World Warrior. Since that time, she has composed many well-known video game scores, including works for Front Mission, Super Mario RPG: Legend of the Seven Stars, Parasite Eve, Legend of Mana, and, most notably, the Kingdom Hearts series.
Shimomura made her debut as a Final Fantasy series music composer with Hataraku Chocobo, although her first major contribution to the series was the score for Final Fantasy XV, released in 2016. She continues to work as a freelance composer for Square Enix and others, and has composed music for over 45 video games and counting.
