TOKYO, Feb. 1 (Xinhua) -- Tokyo prosecutors on Wednesday demanded a prison term of two years and six months for the former chairman of Japanese major business suit retailer Aoki Holdings Inc., Hironori Aoki, for allegedly giving bribes over the Tokyo Olympic and Paralympic Games.

In the hearing at the Tokyo District Court, the prosecution also sought an 18-month sentence for Takahisa Aoki, former vice chairman and younger brother of the former chairman, and a one-year sentence for former senior managing director Katsuhisa Ueda, seeing Hironori Aoki as the main offender who bears the "heaviest responsibility."

The defense asked for suspended sentences as all three had admitted to the bribery charges at the first hearing held in December last year.

The court is set to issue its ruling on April 21.

The former officials of the apparel maker are alleged to have given former Tokyo Olympic organizing committee executive, Haruyuki Takahashi, some 28 million yen (215,000 U.S. dollars) in bribes for favors including on the selection of Tokyo Games sponsors.

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

The case is among a series of bribery cases involving Takahashi over the Summer Games in 2021. A total of 15 people, including those in senior positions at five firms, have been indicted in the bribery scandal.
