A member of the dominant Japanese swimming team, Hamuro had come to prominence by tying the 200 m breaststroke world record in 1935. He won the only international championship he competed in, the 1936 Olympics, in which no 100 m event was held. Notably, Hamuro was using the traditional breaststroke technique, while some of the other finalists were using the later outlawed butterfly stroke. Hamuro won a total of ten titles in breaststroke events at the Japanese Championships between 1935 and his retirement in 1940. After the war, Hamuro worked for the Japanese newspaper Mainichi as a sports journalist. He was inducted in the International Swimming Hall of Fame in 1990.
