The cost of venues for the Tokyo 2020 Summer Olympics will have to be carefully watched and managed, but the Japanese capital¡¯s preparations are otherwise ¡°outstanding,¡± IOC Vice President John Coates said on Wednesday.

Japan said on Monday that the new National Stadium, the centerpiece for Tokyo¡¯s second hosting of the Summer Games, will cost ?252 billion, nearly twice the original estimate, and will be completed in May 2019, two months later than expected.

¡°No doubt there will be some issues on the cost of the overlay,¡± Coates told a news conference in Tokyo following an International Olympic Committee visit that included an inspection of new venue sites.
