As the International Olympic Committee kicked off a three-day debriefing session Monday on the Rio Games, Tokyo Gov. Yuriko Koike said she feels pressured to ensure the Tokyo Olympics succeeds in 2020.

"With the world watching, I accepted the two flags of the Olympics and Paralympics from the (Rio) mayor and felt then that it is now Tokyo's turn," Koike said. "The flag itself was not heavy, but the burden of responsibility which comes along with it was."

"We need to capitalize on the experience from the Rio Games as we prepare for 2020."
