Organisers were impressed with the 'harmonised chequered emblem' which they believe has universal appeal, takes into account Japanese history and incorporates a message of diversity, according to a press release from the organisers.

"Composed of three varieties of rectangular shapes, the design represents different countries, cultures and ways of thinking. It incorporates the message of 'unity in diversity'," they said in a statement revealing the winner.
Tokolo's design was selected from a shortlist of four contenders, all of which were created by Japanese designers:
The chequered emblem is in contrast to the modern design of the original logo (right), which was created by Kenjiro Sano. This logo was dropped after Belgian designer Olivier Debie claimed the design was similar to one he had produced for a theatre in his home country (right) and the agency Hey Studio's logo for the think-tank Rebuild Japan (left).
