Red sun over Olympic gold – a striking design that won over the Olympic organizers instantly. As explained by this article in pingmag.jp, the 1964 Olympics emblem was designed by Yusaku Kamekura in what might seem a flash of genius.
“Legend has it that Kamekura forgot when he had to submit his design and on the day of the deadline got a phone fall. He dashed this out in less than two hours. Of course, that’s not to say that he just did it off the cuff – clearly he had been mulling over the concept for a long time in his head. The design has real impact and perhaps cannot be better for its striking minimalism. It was apparently picked unanimously from twenty other designs. The logo then became the first poster for the Games.
