TOKYO, Japan (AFP) — Tokyo’s 2020 Olympics organisers will scrap the event’s logo after it drew plagiarism claims, reports said yesterday, the latest mishap after a costs furore forced plans for a new national stadium to be torn up.

The decision, reported by public broadcaster NHK and other local media, caps an embarrassing month for Olympic officials as the ditching of the $2.0 billion stadium means the showpiece venue may only be ready a few months before the global event.

The Olympic committee declined to comment on the logo reports, but said it would have held a press briefing last evening.

Japanese media said the committee would hold an emergency meeting before officially announcing they would scrap the emblem due to the brewing controversy.

The final nail in the coffin may have been that designer Kenjiro Sano swiped images posted on the Internet to highlight locations in Tokyo where his logo could be displayed, reports said.

The latest revelations come just days after Olympic officials said they were standing behind the logo and its designer.

The apparent reversal drew an angry reaction from Tokyo governor Yoichi Masuzoe.

“This is a matter of credibility, and I want first and foremost for Mr Sano to explain this fully —

I feel I have been betrayed,” he told reporters.

In recent days Olympic sponsors including national carrier Japan Airlines have started using the logo in advertising campaigns.

The Games have been overshadowed by controversy in the wake of the scrapped stadium and logo issue, in what has become a major embarrassment for Japan.

When Tokyo was chosen two years ago to host the event — a half-century after the 1964 Olympics in the Japanese capital — the city was widely seen as a safe choice with little chance of major delays or funding problems.

Prime Minister Shinzo Abe had promised “guaranteed delivery” of the event and brushed aside concerns about the still precarious situation at the Fukushima atomic plant after the 2011 accident — the worst nuclear crisis in a generation.

Tokyo’s Olympic emblem has been swept up in controversy since its unveiling in July after Belgian designer Olivier Debie claimed it copied work he had done for a theatre company.

Debie has taken the International Olympic Committee (IOC) to court to block it from using the logo.

The IOC has rejected the claims and Japanese officials again on Friday said Sano’s work was original and they had no plans to change it.

“We are confident that the Games’ logo design is original,” Toshiro Muto, director general of the Tokyo Organising Committee of the Olympic and Paralympic Games, said last week.

An online petition with more than 22,000 signatures has called on officials to choose another image.

Tokyo’s logo is based around the letter ‘T’ — for Tokyo, tomorrow and team — with a red circle representing a beating heart.

The theatre’s emblem features a similar shape in white against a black background.

But Sano’s design has “many elements” not seen in the Belgian emblem, Muto had said, adding that the committee twice asked him to tweak his original work to avoid any possible trademark violations.

Sano has rejected the accusations of plagiarism as “baseless”, telling reporters last month: “I’ve never been to Belgium and I’ve never (previously) seen the logo” designed by Debie.

But he has admitted that his team copied designs found on bags used in a promotional beer campaign for Japanese drinks giant Suntory.

Japanese Olympic officials are still smarting over a national stadium fiasco after Abe ordered plans to be torn up in the face of growing anger over its cost.

It was on track to become the most expensive sports stadium in history.

Last week, Japan said it

would slash the cost of the showpiece venue by more than 40 per cent, setting a cap of 155 billion yen (US$1.28 billion) on construction costs.
