Tokyo 2020 Olympic organizers are entertaining the idea that venues built for the games could be financed and run by private-sector companies.

The Tokyo Metropolitan Government, central government and Tokyo 2020 organizing committee have vowed to cut costs for the games, having announced a budget ceiling of ¥2 trillion on Tuesday that the International Olympic Committee warned still has scope for substantial savings.

Organizers are currently in the process of reviewing proposed venues, and agreed to keep swimming and rowing in Tokyo on Tuesday but postponed a decision on the fate of a planned volleyball arena in the city's Odaiba district until later this month.
