The Japanese Olympic Committee on Friday disclosed the results of investigations into allegedly dubious payments Tokyo's bidding team made to a consultancy to win the 2020 Tokyo Olympics.

JOC President Tsunekazu Takeda told a meeting of entities involved in preparations for the 2020 Olympics that an investigative panel has concluded that the massive contracts Tokyo signed with a Singaporean consultancy as part of its bid were not illegal or against the ethics code of the International Olympic Committee.

"We have caused everyone to worry, but the doubts have been cleared up," Takeda told the meeting participants at the Tokyo Metropolitan Government building.
