OCSI currently serves over 300 families who desire this type of education for their children, and we have over 400 students in our (preK-12) day school program.

Our classes (except foreign language) are taught in English, and we use an American-style program that addresses the whole person, is Biblically based, recognizes all truth is God’s truth, emphasizes sharing the Gospel and discipleship, and encourages Biblical thinking and living:

  • Middle school program—Bible, core academics, and exploratories in art, computer applications, Japanese language, music, and woodshop.

History

Legacy class

Okinawa Christian School International was established in 1957 as a school for the children of missionaries living in Okinawa. During the first year, Mrs. Esther Austin taught a class of 11 children in an unused building at the Far East Broadcasting Network’s facility in Chatan.

The school eventually moved into a more permanent facility on present-day Camp Lester (then called Camp Kuwae) consisting of two Quonset huts. Missionary parents who started the school were aware that many other parents desired a Christian, English-language education at an affordable price. Believing that every child deserved an opportunity to receive an education taught from a Biblical perspective, the missionaries decided to open the doors of the school to any child, regardless of religious affiliation.

Legacy campus

Looking forward to the future, OCSI purchased land on Hacksaw Ridge in Urasoe City, a site of fierce fighting during the Battle of Okinawa in WWII. By 1965 students moved into a new, larger school facility (pictured at right). This expansion led to OCSI celebrating its first commencement when the graduating Class of 1969 received their diplomas.

By 1986, OCSI was looking to expand again. OCSI purchased the current campus in 1996 and began classes in this new facility during the 1996-1997 school year.
