Playing career
Born in Nishinomiya in 1951, Sawamatsu won the All Japan Championships singles at 16, the youngest player to do so, and in 1969 won the girls' singles at both the French Championships and Wimbledon. Her sister Junko also played, and her niece, Naoko Sawamatsu, later played on the tour.
On the senior circuit she reached the Australian Open semi-finals in 1973 and, in 1975, the quarter-finals of the Australian, French and US Opens. That summer she and Ann Kiyomura, whom she had met in the locker room at the 1974 US Open, won the Wimbledon doubles unseeded. In November 1975 she beat Kiyomura in three sets for the singles title at the Japan Open, and they won the doubles together. She retired at the end of that year.
