Hironori Aoki, 84, along with two others, has been charged with paying bribes totaling 28 million yen (about 210,000 U.S. dollars) on more than 30 occasions between September 2019 and March this year to a former Tokyo Olympic organizing committee executive, Haruyuki Takahashi, who had influence over the committee's marketing division charged with sponsorship selection.

The trial of Hironori Aoki, his brother and the firm's former vice chairman Takahisa Aoki, 76, and Katsuhisa Ueda, 41, an executive director, is the first to be held in a series of bribery cases related to the Games.

According to the indictment, between January 2017 and June 2021, the three officials repeatedly asked favors of Takahashi for six matters, including the selection of their firm as an Olympics sponsor.

Aoki Holdings supplied uniforms to Japanese team's athletes after becoming an official supporter of the Games in 2018. It also sold jackets with the Games' emblem.

Takahashi is suspected of being involved in other bribery cases and has been indicted four times on charges of receiving nearly 200 million yen (about 1.5 million dollars) in bribes from five firms.
