The Olympic Games, which had been on hiatus during the four-year World War I, returned with the Games of the 7th Olympiad in Antwerp, Belgium in August. 2669 competitors from a total of 29 countries took part in the event. Japan, which made its debut in the Stockholm Games (1912), took part for the second time. In the tennis competition, Ichiya Kumagai took silver in the singles, and in partnership with Seiichiro Kashio took another silver in the doubles, thereby adding Olympics medals to the successes he had previously achieved in the Far Eastern Championship Games.
14 countries participated in the soccer competition (13 from Europe, one from Africa), which was won by Belgium. Great Britain, which had won two gold medals in a row before the Great War, was knocked out by Norway in the first round.
England, the home country of soccer, had dissolved its wartime football and returned to a normal schedule from the 1919-20 season. The league champions this season were West Bromwich Albion (WBA), while the FA Cup was won by Aston Villa.
As for domestic soccer in Japan, Yoshitaka Tanaka, of the Hiroshima Normal Higher School that had learned soccer techniques in a match with a German prisoner-of-war team in Ninoshima the previous year, was appointed teacher and coach at Hiroshima First Junior High School. The school took part in a tournament hosted by Kobe Commercial High School (now Kobe University) in 1920, 1921, and 1922, and despite losing in the final in the first of these years, it emerged victorious for the next two years in a row.
The soccer that Hiroshima had learned from the German prisoners of war would go on to have an influence over the Kansai region as a whole.
