 * The school had a principal sent from Japan until 2001, but since then the principal has been United States-based. This is because when the Japanese government calculates whether a hoshuko has over 100 students and therefore is eligible for such assistance, the government does not include students in classes not oriented towards the Japanese curriculum, nor students who are not in compulsory education levels (as in kindergarten and senior high school). Therefore the Japanese government counted its enrollment as under 100 even though its total enrollment was above 100. This is the only hoshuko in Ohio where area companies do not defray the cost of tuition. In 2005 the school had 130 students. It was formerly held at Regina High School in South Euclid while the office was in Hudson. At one point the office moved to Twinsburg. At a later point the school was located at The Lillian and Betty Ratner School in Pepper Pike.
