An IB World School in Tsukuba Science City

Tsukuba International School (つくば・インターナショナル・スクール, TIS) is an IB World School in Tsukuba, Ibaraki, Japan. Since our founding in 1992, we have been dedicated to promoting international-mindedness in the northern Kanto Region.

Our location in Tsukuba Science City, a place where critical thinking, creativity, and collaboration are highly valued, provides the backdrop for our unique programmes. The school provides a warm and welcoming environment for students of all nationalities.

We offer a rich educational program for students from pre-kindergarten (age 3) to Grade 10 (age 16). We have 127 students in our school (as of Oct 2014). We are authorized to offer the Primary Years Programme (PYP) and the Middle Years Programme (MYP) of the International Baccalaureate (IB). IB World Schools share a common philosophy—a commitment to high quality, challenging, international education. For further information about the IB and its programmes, visit the International Baccalaureate website or the Ministry of Education website (in Japanese).

We are registered as an educational organization (学校法人 各種学校) by Ibaraki Prefecture. This is the standard category for international schools in Japan that are registered as schools in their local prefecture. (We are the only international school registered in Ibaraki Prefecture.) We are also a member of the Japan Council of International Schools (JCIS).
