Yoko Taro was born in Nagoya, Aichi, on June 6, 1970.[2] Yoko's parents were often absent at their jobs, so he was mostly raised by his grandmother, who left a strong impression on him.[3] During his youth, he heard about an incident that would influence his later work as a scenario writer: while an acquaintance was in a shopping street with a group of friends, one of them who was walking along a high building roof slipped and died from the fall.
