Jean-Loup Chappelet, a professor of public management who has long studied the Olympics, believes this summer's Tokyo Games will mark a watershed in the way future games are staged.

The 68-year-old Chappelet, an emeritus professor at the University of Lausanne, counts Olympic Games executive director Christophe Dubi and other International Olympic Committee senior officials among his former students.

In a recent online interview with Kyodo News, Chappelet contrasted Tokyo's first Olympics in 1964 with the firestorm of controversy that has engulfed this year's games, originally scheduled for 2020 but postponed due to the coronavirus pandemic.
