Japan joined the international boycott of the 1980 Moscow Summer Olympics in protest of the Soviet Union's 1979 invasion of Afghanistan. As the historically dominant nation in Olympic judo, Japan's absence fundamentally altered the competitive landscape of the tournament.
Judo competitions at the 1980 Summer Olympics were held at the Palace of Sports of the Central Lenin Stadium in Luzhniki, Moscow, from July 27 to August 2. Male judoka competed across eight events — seven weight categories and an open competition — two more than at the 1976 Games.
With Japan absent, the 1980 Olympic judo medal table was not dominated by Japanese athletes for the first time since Japan had joined the Olympic judo competition, marking a historic shift in the sport's competitive order and elevating athletes from other nations to the top of the podium.
