Ryosuke Nunoi

was a tennis player from Japan.

Early life Nunoi, who came from an affluent Osaka merchant family, was a student at Kobe Higher Commercial School (now called Kobe University).

Career Nunoi was the youngest member of the Japanese squad that toured Australia in 1932 and played in a series of "Test matches" against the home side. In one of these matches he came close to upsetting Harry Hopman, but failed to convert set points in each of the two sets. He did however have a win over Jack Crawford in Perth. At the 1932 Australian Championships, Nunoi was a quarter-finalist in the singles, along with teammate Jiro Sato. Nunoi and Sato remained the only Japanese players to reach the quarter-finals at the Championships (later Australian Open) until they were joined by Kei Nishikori in 2012.

In 1933 he spent a lot of time in Europe, where he played in four Davis Cup ties, against Hungary, Ireland, Germany and Australia. He won singles matches over Emil Gábori, Béla von Kehrling, George Lyttleton-Rogers, Edward McGuire, Gustav Jaenecke and Vivian McGrath.

He also competed in the 1933 U.S. National Championships, as the 10th seed.
