en.wikipedia.org/wiki/Ichiya_Kumagae "Ichiya "Ichy" Kumagae (熊谷 一弥 Kumagai Ichiya, 10 September 1890 – 16 August 1968) was a Japanese tennis player and the first Japanese Olympic medalist." "In 1916, he travelled to the United States with Zenzo Shimizu to compete in the US Open, marking the first participation of a Japanese in one of the Grand Slam tournaments. Kumagae spent a total of three months in the United States, during which he competed in 60 tournaments. He did not lose a single match on a clay court, and lost only four matches on grass courts, rising to the U.S. rank of No. 5."
