The Gakushūin (学習院), or Gakushuin School Corporation (学校法人学習院), historically known as the Peers' School, is a Japanese educational institution in Tokyo, originally established as Gakushūjo (学習所) to educate the children of Japan's nobility. The original school expanded from its original mandate of educating the social elite and has since become a network of institutions which encompasses preschool through tertiary-level education.
