The American School in Japan (ASIJ), an international private day school located in the Chōfu area of Tokyo, Japan, includes elementary, middle and high schools. In consideration of traffic safety issues, ASIJ decided it needed a parking structure for school buses and cars. Although there are those who commute to school by bicycle and train, the majority of students come by school bus or car. The main challenge was the interface between students and vehicles and the need to alleviate traffic flow and improve safety. The parking structure was a functional necessity, but when Tange Associates reviewed the campus layout, we recognized the need for a larger scale renovation of the facilities.The parking structure would replace the existing tennis courts that could be relocated to the roof of the building, but in addition we realized that the new facilities could provide much more to the campus, and we began to expand our ideas with the design process. We considered the significance of the school campus experience and contemplated several concepts that highlight that experience, for example, the school "gate" and the sense of arrival it provides, monuments that act as campus landmarks for students and evoke memories for the alumni, and gathering spaces that facilitate communication among students and faculty. ASIJ's new school buildings are highlighted by the grand entrance that displays a reinterpretation of the ironwork motif of the original iron gate that now stands in one of the school courtyards. The dramatic entrance provides a new image for the school and celebrates each arrival through this main gate of ASIJ. Passing through the gate, faculty, students, and alumni experience the "sense of arrival" and visitors are inspired by the grandeur of the space. In our philosophy of the design of educational buildings, open spaces where people can gather are important because those are the places where students and teachers can exchange ideas and spend time together in a relaxed atmosphere outside the classroom. That was our thought process for the creation of the plaza in the front of the school. We also created the plaza as part of the design of a unified and contemporary school image. The portico or covered walkway, in line with the athletic building, continues from the main gate to the entrance of the school building itself. The portico integrates the entirety of the space, including the entrance plaza and surrounding buildings. It also allows a larger area for drop off of the children by the school buses, improving safety for people and cars. The multi-function athletics building, coupled with the entrance gate, provide the structure for the bus and car parking, as well as the student drop-off and pick-up area, on the ground floor. A dance studio is also located on the ground floor. On the second floor are the fitness center and tennis courts.In accordance with ASIJ's efforts to comply with environmental standards, the project employs a geothermal air conditioning system, green walls and solar panels.
