Keio University has a long tradition of comprehensive primary and secondary education. Keio's affiliated elementary, junior, and senior high schools have been part of Keio operations for more than half a century. Students are encouraged to take initiative in all aspects of school life and are offered a multitude of opportunities to discover and realize their individual potential. While all of Keio's affiliated schools share the same overall educational philosophy, each possesses a unique personality and its own set of policies, which set the course for fostering both diversity and competence among the students.
