Japanese Olympic Committee (JOC) chief Tsunekazu Takeda, who is under investigation for suspected corruption, said on Tuesday he will step down from his position when his term ends in June and resign from the International Olympic Committee.
French prosecutors have questioned Takeda in Paris and placed him under formal investigation in December for suspected corruption in Tokyo's successful bid to host the 2020 Summer Games.
Takeda, who was president of the 2020 bid committee, said during a JOC board of directors meeting in Tokyo he would step down and not seek re-election.
At a news conference later on Tuesday, Takeda said: "I don't believe I've done anything illegal."
When asked why he had not resigned with immediate effect, Takeda said: "It pains me to have created such a fuss, but I believe it is my responsibility to serve out the rest of my term."
Takeda had been head of the JOC since 2001 and his resignation leaves a cloud hanging over both the national committee and the organisers of the Tokyo 2020 Games.
He also serves on Tokyo 2020's Executive Committee but it was unclear whether he would also be standing down from this role.
French investigators have led a years-long probe into corruption in athletics and in early 2016 extended their inquiry into the bidding and voting processes for the hosting of the 2016 Rio de Janeiro and the 2020 Tokyo Olympic Games.

Takeda has denied any wrongdoing, saying that there was nothing improper with the contracts made between the committee and the consultancy and that they were for legitimate work.
The IOC's ethics commission has opened an ethics file on Takeda, who chairs the IOC's marketing commission. Takeda has been a member of the IOC since 2012 and was president of the Tokyo 2020 bid committee.
Tokyo 2020 organisers have yet to comment on Takeda's resignation.
The JOC is expected to elect a new president in June during regular biennial voting.
Japanese media have reported that former Olympic judo champion Yasuhiro Yamashita and Japan Football Association President Kozo Tashima, both JOC Executive Board members, could be in line to take over.
Olympic hopeful Hong Kong swimmer To dies at 26
Kenneth To, a record-breaking Hong Kong-Australian swimmer who had his sights on the 2020 Tokyo Olympics, died suddenly after a training session in the United States, officials said on Tuesday. He was 26.
To, who holds 17 Hong Kong records and won a silver medal as part of Australia's 4x100 metre medley relay squad at the 2013 world championships, was in the United States for a three-month training programme at the University of Florida.
To, who was born in Hong Kong and raised in Australia, died on Monday. The cause of death was not disclosed.
"He felt unwell at a training session and was taken to hospital where sadly, he passed away," the Hong Kong Sports Institute, where To was an Elite Scholarship Athlete since 2016, said in a statement.
"He was extremely popular and loved by his teammates and competitors. Kenneth was known as a truly exceptional person, warm, funny and kind. His sudden passing is a huge loss to local sports."
To, who transferred his nationality in 2016 to swim for Hong Kong, first began to shine at the 2010 Youth Olympic Games in Singapore where he earned six medals, including gold in the 4x100m medley.
In 2012, To won the men's overall title in the FINA Swimming World Cup, before claiming three medals in the FINA World Swimming Championships in Istanbul.
He was also a member of the Australian teams at the 2014 Commonwealth Games that captured gold in the 4x100m freestyle and silver in the 4x100m medley.
World swimming governing body FINA said in a statement it learned with "immense sadness" about To's death and described him as a reference and example for the youth in the territory.
Australian swimmer James Magnussen posted a tribute to To on Instagram: "Shocking news to hear of the passing of my competitor but most of all, friend - @kennethkhto. We've been racing each other and making teams together since we were 16.
"He will remain one of the fiercest competitors I've ever stood on the blocks next to. I firmly believe that for a long period he was pound for pound, the best swimmer in the world.
"RIP little guy, you won't be forgotten."
