Tokyo organizers submitted their official bid books to the International Olympic Committee for the 2016 Olympics.

"The books were delivered to the IOC today in Lausanne," a Tokyo 2016 spokesman said Thursday.

The documents, which run into hundreds of pages and are spread over several volumes, provide detailed answers to a questionnaire from the IOC about all facets of the bids, including budgets, sports venues, government guarantees, hotel accommodation, security and transportation.

Tokyo is competing with Chicago, Madrid and Rio de Janeiro.
