TOKYO (AP) -- Tokyo will bid for the 20-16 Summer Olympics that Chicago wants.
The Japanese Olympic Committee notified the International Olympic Committee today of its intention to offer Tokyo as a candidate.
Chicago, Madrid and Rio de Janeiro, Brazil have also been approved as candidates by their national Olympic bodies.
Tokyo hosted the Summer Games in 1964.
Chicago Mayor Richard Daley says his city faces tough competition from the growing list of international contenders that hope to lure the Games.
Chicago has never hosted the Olympics.
The I-O-C will select the winning city in 2009.
All candidate cities must submit initial bid files to the I-O-C by September 13th.
Other possible contenders include Rome; Prague, Czech Republic; Doha, Qatar, and Baku, Azerbaijan.
