Tokyo Gov. Naoki Inose left for St. Petersburg on Tuesday to deliver a presentation at an international sports seminar involving the three cities bidding to host the 2020 Summer Olympics.

In the "Sportaccord Convention," Tokyo, Istanbul and Madrid will make their presentations Thursday before International Olympic Committee executives.

"I would like to properly explain Tokyo's excellence, that it has enough management ability and is also friendly to athletes. I have confidence," Inose told reporters before his departure.
