Established as a trust in 1988 to meet the needs of parents who wished their children to receive a British style education in Tokyo, BST was officially opened by
Margaret Thatcher in September 1989, with 63 students, and rapidly expanded. By 1993, there were 200 students in the entire school. The existing site could no longer accommodate the growing demand for places and a modern building with improved facilities (the current BST Shibuya site) was opened in
Shibuya on 14 May 1998 for over 300 children aged three to eleven. In 2000 the School opened a second site at the municipal Shibuya Elementary School (SES) to accommodate a small number of older students up to age thirteen; the
Upper School. In 2003 SES was demolished and the Upper School had to be moved to another municipal facility on the far side of Shibuya Station, the
Owada Junior High School. To address the issue of inadequate facilities, part of the school was moved in August 2006 to newly renovated accommodation on the campus of the Showa Women's University, located a 10 minute bus ride away to the west of Shibuya station. The original site, BST Shibuya, now accommodates 350 Nursery to Year 3 pupils in refurbished facilities. The Showa campus underwent construction during the summer of 2017 to accommodate the rising number of students joining the school, adding new classrooms, libraries, study areas and more. BST Showa offers educational provision from Year 4 to 13 for over 620 students with extra-curriculars, such as sports fixtures and music clubs. Key Stages 4 and 5 include
IGCSE,
A-Levels, AQA BAC and the International Duke of Edinburgh Award. == Locations ==
