History	History CAJ began in 1950 as the Japan Evangelical Christian School, established by missionary families seeking an English-language Christian education. It opened with 13 students and one teacher, Miss Nettie Dyk. In fall 1951 the school moved to Higashi Kurume on land purchased from an imperial dairy farm, and a boarding program began; by fall 1952 the student body reached 92. In 1961 the school reorganized under a board of directors drawn from six evangelical mission organizations. Today CAJ serves approximately 450 day-school students and more than 300 in Parallel Educational Services, operating in English with a North American curriculum.	History KA International School was co-founded in 2006 by Jonathan Yaffe and Charles Knudsen. It began in a small house in Tokyo with a focus on high school education, aiming to provide a nurturing and supportive environment. The school operates under Kikokushijo Academy, the parent company, and in 2014 expanded to include Elementary and Middle School, creating a continuous educational pathway from Pre-K to Grade 12. As KAIS grew, it began serving students from Pre-Kindergarten through Grade 12, building a cohesive, globally oriented learning community. Today, KAIS emphasizes academic excellence, creativity, and a global perspective within a small, international setting.
Community	Community CAJ's community spans more than 25 countries, with day-school and Parallel students from a broad international mix. The school offers a wide range of co-curricular activities, including Brain Bowl, Debate, Drama, Robotics, National Honor Society, Student Council, and numerous sports across middle and high school. The CAJ community also participates in regular events and gatherings organized by CAJ and the PTA, such as New Family Orientation, Welcome Parties, Fall Festival and Bazaar, and a Christmas Baked Goods Delivery to neighbors. Prayer and spiritual life are integrated into community life, with parent prayer meetings and a community forum that encourages prayer, feedback, and volunteering.	Community KA International School fosters a welcoming, curious, and compassionate community.

Parent teacher association	Parent teacher association The CAJ PTA is an organization that supports the ministry of Christian Academy in Japan in fulfilling its mission of equipping students to serve Japan and the world for Jesus Christ.

PTA members help fund scholarships, service projects, and equipment, and reach out to the greater CAJ community and neighborhood. Throughout the academic year the PTA hosts a variety of events and activities, with parents assisting in Scripture recitations, baking, setting up and serving food, and praying.

Spanish is offered in tracks Spanish I–IV for non-native learners. EAL (Effective Reading and Writing) supports non-native English learners, and graduation requires four World Language credits (including Japanese Foundations through Comprehensive and Spanish I–IV). The World Languages Department emphasizes developing the four language skills—reading, writing, speaking, and listening—and aims to cultivate culturally aware, biblically grounded communicators.	Language provision English is the primary instruction language at KAIS. Japanese is offered as a language program, primarily in Elementary, with differentiated tracks for non-native and native speakers. Non-native learners receive essential language development, while native speakers work on more advanced reading, writing, and kanji. An English-language support framework is in place to assist non-native speakers in developing English proficiency.

Admissions	Admissions
Admissions	Admissions CAJ uses rolling admissions, and the school year runs from late August to early June. For April admission, CAJ strongly encourages applications before January 15 to enable timely processing, and applications submitted after May 1 may take longer due to the summer break. Parents should plan for a process that can extend through the school year and may involve conversations with the Admissions Coordinator before starting the formal steps. 1. Apply online. Complete the online application and assemble the required documents: birth certificate or passport, confidential teacher recommendation form, transcript, pastor's recommendation (if applicable), and pay the application fee. A testing fee may apply if testing is required. The admissions team reviews the complete application and notifies applicants after the review. 2. Notification of results. Once the complete application has been reviewed, applicants are notified of the outcome. This communication occurs in writing. The timing is not fixed and can depend on the overall review process. 3. Testing and interviews. Applicants who pass the initial screening are contacted to arrange any required testing and interviews. Kindergarten and Grade 1 receive a readiness test; non-native English speakers may need English language testing at any grade level; standardized test documentation is required for Grade 2 and above, and a test may be requested if documentation is unavailable. Both parents and the student are interviewed, and Skype or other digital options may be used for families outside the Tokyo area. 4. Admission decision. Decisions are based on factors including class availability, English language ability, presence of special needs, and classroom dynamics. Admission decisions are communicated in writing (email and postal mail), and most families are notified within 1–2 weeks of the testing and interview. Note on fees and timing: CAJ publishes a fee schedule in Japanese Yen, with upfront application and testing fees and post-acceptance fees such as entrance, registration, and facilities charges, plus tuition by grade level. See the General Fee Schedule for specifics.	Admissions 1. Get to know KAIS. Book a school tour or contact the admissions office for more information. Tours help families understand KAIS programs and entry points, and admissions staff can answer questions about grade levels and how to proceed. The initial visit provides insight into whether KAIS aligns with your child's needs and learning style. 2. Create an Alma Account. Start your application by creating an Alma account, KAIS's student information system. This account is used to initiate and track the enrollment process and submit documents. A properly created Alma account is required before you can begin the formal enrollment application. 3. Start Enrollment Application. Once your Alma account is created, begin the application and provide the required documentation listed below. Required documents include the admissions application (through Alma), school transcripts/records from the past two years, two reference letters from the child's current or recent Math and English teachers, and detailed information on any special educational support needs. For Pre-K or Kindergarten (ages 3-6), you must also provide a Pre-Enrollment Medical Examination form and a medical check record by your doctor every six months until entry to Grade 1. Please ensure all learning needs are fully disclosed to avoid issues. 4. Document Screening. Your completed application will be reviewed by the Admissions Team. Our Admissions Director will track your progress and provide support along the way. This step ensures that KAIS understands the applicant's background and needs and helps coordinate next steps. 5. Trial Day. After reviewing all documents, we invite the student for a trial day. During the visit, the student will take placement tests in Mathematics and Language Arts to assess their level and needs. For overseas applicants, KAIS conducts an online interview instead of an in-person trial. 6. Acceptance Review and Enrollment Fees. After the trial day, KAIS educators review the child's performance to determine if KAIS is a good fit. If accepted, the family is notified by email and begins enrollment. The enrollment process includes paying the Enrollment Fee (one-time) and Building Maintenance Fee (one-time), along with Materials Fee and Trip & Event Fee as applicable to the grade. Tuition is charged on an annual basis. 7. Required Enrollment Documentation (summary). You will need to provide the admissions application (through Alma), school transcripts/records from the past two years, two reference letters from the child's current or recent Math and English teachers, and detailed information on any special educational needs. For Pre-K or Kindergarten (ages 3-6), you must also provide a Pre-Enrollment Medical Examination form and a medical check record from your doctor every six months until entry to Grade 1. Open communication about learning needs is essential to a positive enrollment experience.
