Kansai University Dai-ichi Senior High School and Dai-ichi Junior High School, formerly known as Kansai Koshu Gakko, aim at developing and nurturing both the mental and physical health of their students. The Dai-ichi Senior High School opened in April 1948, and has a full time comprehensive course that requires three years of study, which consists of ten classes each year. The Daiichi Junior High School was opened in April 1947 as a compulsory education school. This school also offers three years of education, six classes each year. Both schools have educational policies of:

1. Respect for the unlimited capabilities of youth and for enlightening students to bring out their potential, 2. Pursuit of the true happiness of students, and 3. Nurturing individuals who are enterprising, ready to observe discipline, and cooperative and self-governing, with an emphasis on justice and honesty.

  Both were boy's schools except for a certain period in the postwar years, but the Dai-ichi Junior High School became coeducational in April 1995 and the Dai-ichi Senior High School did so in April 1998.
