Atsushi Miyagi
Atsushi Miyagi is a Japanese former tennis player. In 1955 he and Kosei Kamo became the first Japanese players to win a Grand Slam tournament.
Career
In 1955 Miyagi won the U.S. National Championships men's doubles title at the Longwood Cricket Club in Boston with compatriot Kosei Kamo after a five-set victory over Americans Gerald Moss and Bill Quillian. Hurricane Diane roared through New England in August 1955, flooding the tennis courts and delaying the tournament for a week. When the tournament resumed many of the leading players such as Ken Rosewall, Tony Trabert, Lew Hoad and Vic Seixas had already left which devalued the men's doubles draw.Miyagi won the Japanese tennis championships in 1954, 1955, 1957 and 1960.
Between 1952 and 1963 he played in 16 ties for the Japanese Davis Cup team.
At the 1962 Asian Games in Jakarta, Indonesia he won a gold medal in the men's doubles competition with Michio Fujii and a silver medal in the men's singles competition.
