Tokyo will learn early Sunday whether the International Olympics Committee vote in Buenos Aires results in the capital becoming the host of the 2020 Summer Games. Winning the nod to hold the prestigious global sporting event is cause for celebration, especially when considering the economic rewards.

"As a measure to stimulate Japan's economy, I think it will bring positive effects, including boosting individual consumption," Finance Minister Taro Aso told a news conference Aug. 21.

The Tokyo Metropolitan Government estimates that hosting the 2020 Games will produce economic effects worth about ¥3 trillion from Hokkaido to Okinawa.
