The Suspended Roof Above Harajuku

In Kamikita, Shibuya City, on a hill bordering the western edge of Meijijingu, the Yoyogi National Gymnasium was completed in 1964. The complex comprises the First Gymnasium and the Second Gymnasium; the First Gymnasium, designed by architect Kenzo Tange, is recognised worldwide as a masterwork of suspension-structure architecture. Its total floor area is approximately 28,705 square metres.

The most striking feature is visible from outside: two main masts, standing about 40 metres tall and set roughly 126 metres apart, from which a vast cable network suspends the building’s spiralling roof. The technique — a double-layer suspension system in which the primary cables carry a secondary radial layer — was unprecedented in building construction at the time. Structural engineering was led by Professor Yoshikatsu Tsuboi of the University of Tokyo. Their collaboration produced a vast, column-free interior where every spectator has an unobstructed view of the playing area below.

From 1964 to a Living Monument

The First Gymnasium served as the swimming venue during the 1964 Tokyo Olympics. Completion came only weeks before the opening ceremony, the project driven to the finish by round-the-clock construction, as records from the time attest.

The building has continued to function as an arena for sport and concerts for more than sixty years. In May 2021, it was designated a National Important Cultural Property by Japan’s Agency for Cultural Affairs, which described it as “a pinnacle of postwar architecture, possessing a dynamic exterior and a majestic interior space.” Applying cable suspension to a major public venue at this scale was a pivotal moment in the history of large-span structural design, and its influence on subsequent architecture and civil engineering remains widely acknowledged.

Summary

The Yoyogi National Gymnasium First Gymnasium was completed in 1964, with a total floor area of approximately 28,705 square metres. Designed by Kenzo Tange and engineered by Yoshikatsu Tsuboi, its suspended roof has been in continuous active use for more than sixty years and now carries the status of a National Important Cultural Property. A short walk from Harajuku Station, its sweeping silhouette is a worthwhile stop on any architectural tour of Tokyo.
