Keio Junior High School was established in 1947 and accepts about 240 students per year i.e. about 140 boys and 50 girls. However, about half of the slots are usually taken up by those from the Keio-affiliated primary school so it is extremely difficult to enter its junior high school from non-Keio primary schools. Actresses who had graduated from the Keio primary school and junior high school include Nitani Yurie, Shibamoto Yuki and Kikuchi Maiko.
