It's best to ask — circumstances can change at any time.
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.
KA International School fosters a welcoming, curious, and compassionate community. The school uses a House system with four houses—Seiryu, Byakko, Suzaku, and Genbu—to unite students through competition and collaboration. The KAIS community offers diverse co-curriculars, including robotics, filmmaking, broadcasting, Model UN, history bowl, sports, and arts, with Project Week events that pause regular classes for major projects such as Humanities and Science Fair. This environment supports social growth, peer learning, and a sense of belonging among students from many nationalities.
KA International School does not publish a formal Parent Teacher Association (PTA) on its public materials. The school's governance features a Board of Trustees and active school leaders, rather than a named PTA. Parents engage with the school through admissions events and campus visits, such as High School Open House and Elementary/Middle School Open House, as well as online information sessions. Public pages describe family involvement through school communications and events rather than a dedicated PTA structure. Volunteer opportunities or parent groups are not listed on the site; inquiries about parent involvement are handled through the school's contact channels.
KA International School (KAIS) is an English-based international school in Tokyo serving children from Pre-K through Grade 12. Students study an American standards-aligned program (including references to American Common Core Standards) and KAIS offers Advanced Placement (AP) courses in high school. The school emphasizes English as its first priority and teaches Japanese as a subject. Facilities highlighted by the school include science labs, libraries, a gym, a music room and an art room. A distinctive feature is KAIS’s “Visible Learning” focus. This is possible as the school has earned Visible Learning Certification through Corwin. High school life also includes an annual “Experience Japan Trip”.
