Old residences for US military families were knocked down as another physical remnant of the American occupation disappeared. And up rose a structure, often cited as one of the most beautifully designed for an Olympic Games – the National Gymnasium. In 1964, 11,000 spectators would watch swimming and diving events in the National Gymnasium, that, from the outside appears to uncoil and breathe, and from the inside inspires the awe of the great cathedrals of Europe. Danish diver, Soren Svejstrup wrote me about the first time he entered Kenzo Tange’s dream building. “When we arrived the first day at the pool, into this wonderful building, our coach said, ‘This is the place every swimmer and diver want to be buried when the time comes’.”

The first reaction of Dutch swimmer, Ada Kok, who won two swimming silver medals in this building was, “Wow! We looked up, completely flabbergasted. It had an Olympic size pool, and yet, once inside, it felt really cozy, and so typical Japanese with its breathtaking roof.”

Two-time gold medalist, American Donna de Varona said she would kid the Princeton basketball star, Bill Bradley, about the size of the annex, which was the smaller Tange version of the National Gymnasium and where the basketball games were played for a maximum of 4,000 spectators. “That basketball arena was so small and our swimming stadium was big and beautiful, state of the art and breathtaking.” 

This site gives a detailed explanation and illustration of Tange’s genius use of cables, curves and light. That year in 1964, Tange completed an actual cathedral, St. Mary Cathedral in Tokyo. But you could say, the National Gymnasium was his first.
