About Ryosuke Irie
Ryosuke Irie (入江 陵介, Irie Ryōsuke; born 24 January 1990) is a Japanese retired competitive swimmer who competes in backstroke events. He is a Kindai University student in Osaka. He won a silver medal in the 200 metre backstroke and a bronze in the 100 metre backstroke at the 2012 Summer Olympics, along with a silver in the men's 4 × 100 m medley with the Japanese team. His backstroke technique has often been compared to Roland Matthes, who was described as the Rolls-Royce of swimming. When he first joined, Irie was one of the slowest swimmers in the elite Itoman Toshin swimming school in Suminoe Ward, Osaka. He joined the school because his older brother, Shinpei Irie, who had won numerous national-level competitions, was in the program. In 2005 he won the national high school championships in 200 meter backstroke when he was a first year grade student.
