Kenjiro Sano, whose logo design for the 2020 Summer Olympics is at the center of a plagiarism row, will hold a news conference Wednesday to clarify his position, the Tokyo 2020 Organizing Committee said Monday.

The designer of a Belgian theater logo who claims the recently unveiled emblem for the 2020 Tokyo Olympics resembles his design sent a letter Friday to the International Olympic Committee and the Tokyo organizers, seeking its retraction.

Olivier Debie's lawyer said the letter also asks the two organizations to provide a response within eight days, and that if no response is made he will file an action with a Belgian court this month seeking an injunction against use of the logo.

Sano last week denied plagiarizing the logo for Theater de Liege, saying in a statement issued by the Olympic organizers that he had no previous knowledge of the Belgian design and that he never referred to it when he was creating his logo.

The IOC and Tokyo organizers have said they checked international trademarks before deciding on the logo and have agreed that there is no problem.
