Masahiko Kimura

was a Japanese judoka and professional wrestler. He won the All-Japan Judo Championships three times in a row for the first time in history and had never lost a judo match from 1936 to 1950. In submission grappling, the reverse ude-garami arm lock is often called the "Kimura", due to his famous victory over Gracie jiu-jitsu co-founder Hélio Gracie. In the Japanese professional wrestling world, he is known for being one of Japan's earliest stars and the controversial match he had with Rikidōzan. Provided by Wikipedia
