Bach has drawn scattered protests during his visit to Japan, where the latest poll in the Asahi Shimbun newspaper showed 55 percent of respondents opposed holding the Games this summer
The Japanese government and the International Olympic Committee made the decision last March to postpone the 2020 Olympics until July 2021 because of the pandemic.
Organisers have stressed they are determined to press ahead with holding the Games this year.
According to Japanese Prime Minister Yoshihide Suga, the dekayed Tokyo Olympics would go-ahead as scheduled in July 2021, even as the country grapples with an unexpected surge in coronavirus cases.
The games, now scheduled for July, involves over 11,000 athletes across the globe with a combined budget of $15 billion.
Organisers have been assessing the financial impact of the delay since the Japanese government and International Olympic Committee (IOC) decided in March to postpone the Games until 2021.
