There is also an early learning center (nursery-kindergarten) for children aged 3–5 located in the Roppongi Hills complex in downtown Tokyo.

Beginning life in rented rooms in the Kanda YMCA, the Tokyo School for Foreign Children, as it was then known, quickly attracted a growing numbers of students from around the world and soon needed to move to a more permanent home in Tsukiji.

The building was deemed unsafe after the Great Kanto earthquake, and classes resumed on the Friends Mission compound in Shiba, in the former home of the Bowles family.

[1] In the early 1920s Frank Lloyd Wright, who was in Tokyo building the Imperial Hotel, drew designs for a proposed new campus,[2] as did Antonin Raymond.

Between 2010 and 2013, a series of changes designed by Paul Tange addressed campus traffic flow, added new athletic facilities (including raised tennis courts with covered bus drop-off below, and replaced the Multipurpose Room, along with the Elementary music and art classrooms with the CADC (Creative Art Design Center) which not only houses the music and art classrooms, but also houses multiple rooms for the high school and middle school Design Technology classes, a Japanese Culture center, and holds multiple meeting rooms.

[11] ASIJ follows a broadly American curriculum and Advanced Placement courses are offered for high school sophomores, juniors and seniors.

The school started keeping baseline data on energy usage and garbage volumes in 2007 when they began composting cafeteria waste and campus leaves using earthworms.

In 2009, with the help of government funding and private and corporate donors, the school installed solar panels on top of the gym and pool buildings which have a maximum capacity of 80 kWh.

A 2010–2011 carbon footprint audit by ECO3 Design has given the school new goals to replace heavy-oil boilers and install a ground source heat exchange system.
