Tokyo's new stadium being built for the 2020 Olympics and Paralympics will be completed two months ahead of schedule in November 2019, according to Japanese organisers, but will not be ready in time to host Rugby World Cup matches.
The project's architect Kengo Kuma had recently claimed that construction of the Stadium could be sped up with a view to having work finished ahead of the 2019 World Cup, the first to be held in Asia, due to get underway on September 20 that year.
International Olympic Committee (IOC) vice-president John Coates was informed that the completion date had been moved from January 2020 to November 2019 during a two-day Project Review visit to assess the state of the preparations.
The move has been made in order to allow more test events to be held at the Stadium.
The Stadium has been a major embarrassment for Tokyo 2020 organisers, with the saga starting when the initial design by Iraqi-British architect Zaha Hadid was axed due to rising costs.
A cheaper design by Kuma has been selected as the replacement, but he has now been embroiled in a plagiarism rowl with Hadid claiming that his effort has "significant similarities" with hers.
The architect of the new Stadium has vehemently denied the allegations.
The IOC have hailed the progress of organisers, despite the controversy surrounding the venue and the plagiarism row which forced the scrapping of the original logo for the Games.
Coates, also President of the Australian Olympic Committee, still believes everything is going well.
“For a city that's four years out to the Games, I don't think we've ever seen a city more prepared,” he said.
“Four years out, we couldn't be happier.”
insidethegames exclusively revealed last week that Belgian designer Olivier Debie has still not resolved his plagiarism conflict with the IOC, which forced the initial emblem to be scrapped.
The graphic designer began a lawsuit in August after claiming that the original logo, designed by Kenjiro Sano, was overly similar to one he created for the Théâtre de Liège in Belgium.
Tokyo 2020 opted to scrap the emblem and launched a process to find a replacement, with the four shortlisted designs now being subjected to plagiarism checks.
Although the issue has caused embarrassment to Tokyo 2020, Coates claimed is happy with the “level of public engagement” during the process to find a new logo after it was opened up to all Japanese adults.
This prompted criticism from the American Institute of Graphic Arts, however, who believe the open contest is “speculative” in nature and “disrespects” the design profession.
They also feel the cash prize of ¥1 million (£5,400/$8,200/€7,600) on offer to the winner is not enough for a logo which will be seen across the world millions of times.
As well as issues with the logo and stadium, Tokyo 2020 also came under fire following the publication of the second World Anti-Doping Agency Independent Commission report, where the Japanese capital being awarded the Games was implicated in the corruption scandal in athletics.
The IOC told insidethegames that they will study evidence suggesting an athletics sponsorship deal may have unfairly influenced Tokyo's victory in the race for the 2020 Olympics and Paralympics to "better understand" the claims being made.
