Masaharu Taguchi

Masaharu Taguchi (田口 正治) was a Japanese freestyle swimmer. At the 1936 Olympics, he won a gold medal in the 4 × 200 m relay, setting a new world record. In the individual 100 m race, he finished almost simultaneously with Masanori Yusa and Shigeo Arai and was placed fourth, although photographs suggest he was second.

Taguchi graduated from Rikkyo University, later worked at a Daimaru department store and coached swimming at a local Daimaru swimming club. He was recruited 1961 to prepare the national swimming team for the 1964 Tokyo Olympics.
