K. International School Tokyo was founded in 1997 as a private, co-educational, secular day school serving the international community of Tokyo from pre-kindergarten to Grade 12. In July 2000, KIST attained recognition as an educational corporation (gakoo hoojin) from the Tokyo Metropolitan Government and has grown to a population of nearly 600 students.

K. International delivers its educational program through the International Baccaulareate (IB) which provides independent international curriculum frameworks: the Diploma Programme (DP) is a widely recognized international high school curriculum used for entrance to universities around the world; the Middle Years Programme (MYP) for Grades 6-10; and the Primary Years Programme (PYP) for students aged 3 to 11.

K. International School Tokyo became the first school in Tokyo to receive accreditation in all three International Baccalaureate programmes (PYP, MYP, DP) in 2004 and continues to be the only school in Tokyo to be fully accredited to deliver all three programmes. One of the merits of having all three IB programmes is the systemized progression of the development of the required knowledge and skills that is necessary to be successful in a global economy.

K. International School Tokyo's student body is comprised of around 50 nationalities, with the majority of students being long term international residents of Japan which provides a stable population base. One of the characteristics of our student body is the existence of a large number of hard working students who have an outstanding volunteering spirit. This generates a positive influence on other students and the learning environment. Only 45% of the students in IB schools worldwide take the full diploma, and approximately 79% of these candidates are awarded the Diploma. Here at K. International School Tokyo, however, 99% of students challenge themselves to undertake the full IB Diploma course. In the May 2009 examination session, 90% of our students received their IB Diploma. The highest score awarded was 45 points out of a possible 45, followed by 39 points.

In the past three years our graduates have achieved some excellent results and have been awarded scholarships from leading universities around the world and in Japan. This has been possible due to the progressive development of students through all three IB programmes. It is also because we value a learning environment that cultivates students' hearts and minds and encourages them to do their best.
