Japan Women’s University is one of the oldest women’s universities in Japan and is situated in central Tokyo in Mejiro, amidst numerous other educational facilities. In conjunction with its 120th anniversary in 2021, they have launched a campus renewal masterplan for which we are responsible. The reconstruction of the library is the initial phase of the plan.
Since the new library would face Mejiro Dori, which is a major roadway in the Mejiro area, the request was that this building become a new symbol of the university and also provide space for innovative learning and interaction for students.
As opposed to the previous stacked design, we thought the use of slopes and an open ceiling would vertically connect the different floors, fostering an integrated experience as students search for books and socialize in the building. The slope is built along the natural incline of the grounds and gently spirals around each floor. It connects to terraces and closed-off rooms with differing widths along the way, which gives unique character to each location.
From the ground level and downward to the underground compact shelving areas, and the fixed shelving on the mid-level floors to the lecture hall and browsing spaces on the top floor, the spaces connect to each another, creating a single large room. We enabled a seamless continuum of areas so that students could enjoy a variety of experiences under one roof. One could attend a lecture, then take a break afterwards at the terrace, for example. It is our hope that this building would serve as a new library model that is versatile and adaptable to the evolving needs of the community according to the times, even as it serves the university for generations to come.
