On July 24, 2015, Tokyo released their official 2020 Olympic and Paralympic Games logo. The mark, created by the office of well-known designer Kenjiro Sano was unveiled to tepid even negative reviews. While many seemed to liked it, many more decried it as stale and lifeless, not becoming of the spirit of the Olympic Games.
Almost immediately, charges of plagiarism were levied against the Tokyo Games organizing committee and Sano’s office. Belgian designer Olivier Debie accused Sano of copying a graphic mark he created for the Théatre de Liège in 2011, and later took legal action to block the International Olympic Committee (IOC) from using the design.
