Covenant Community School International (CCSI) is a bilingual, international Christian school operated through our MTW team. CCSI currently has about 50 students, elementary through high school, with both English and Japanese language tracks.
CCSI helps support missionaries on the field by providing affordable, gospel-centered Christian education to children of missionaries and other internationals, as well as supporting the growth of the church in Japan through helping to educate and disciple the next generation of church members and leaders.
Our history: Covenant Community School International (CCSI) began as Keiyo Christian School (KCS) in the early 1990’s, with the goal of providing an English education for expatriate missionaries living in Japan.
In 2006, KCS extended its mission to include Japanese education for nationals and other nationalities, changing its name to CCSI. Presently, CCSI uses two buildings on Oyumino Christ Church’s Honda campus.
In 2025, MTW incorporated a distinct CCSI Team to manage and support the school's operations and outreach.
