Tsunekazu Takeda, president of Tokyo 2020, said he has confidence in his own abilities to do the work of two men in order to bring the Olympic Games back to Japan's capital.
Takeda, president of the Japanese Olympic Committee, was elected as the country's only member of the International Olympic Committee prior to the London 2012 Olympics.
During Tokyo's failed bid for the 2016 games, Japan had two IOC members - Shun-ichiro Okada and Chiham Igaya - lobbying for votes, but both have since been forced to retire because of their age, although they are both now honorary members.
Speaking during the IOC evaluation commission visit to Tokyo, Takeda told Sportcal: "Of course for 2016, we had two IOC members from Japan. I am the only one currently, but whether that has a significant impact on bidding activities, I don't think so. Maybe I will have to do extra work. That is OK.
"We have to keep making the upmost effort so this does not come as a de-merit to our bid."
Takeda also referred to 2020 games rival Istanbul and the fact that Turkey's sole IOC member is Ugur Erdener, president of the Turkish Olympic Committee.
Takeda said: "Turkey has one IOC member too, so it is one versus one."
However, he did not mention Spain, which has three IOC members - José Perurena, Marisol Casado and Juan Antonio Samaranch Junior - pushing Madrid's 2020 Olympics credentials. Samaranch sits on the IOC executive board.
The host of the games will be decided at the IOC Session in Buenos Aires on September 7.
