Kojima played an active role as an ace pitcher at baseball in Nittai Ebara High School Baseball Club in Japan, and after graduating, he joined Japan Pro Wrestling in 1957, but left in 1960. Then Matsuda went to Peru. This travel is repelled by unwritten rules such as the upper and lower relations that Rikidozan brought from the customs of sumo room, and Japan's original mental theory . In Peru, he worked in the name of Ernesto Kojima. Later, after moving to Mexico through the United States, the ring name was changed to Kojima Saito, Great Matsuda, and Hiro Matsuda. The name “Matsuda” was a ring name given to two Japanese wrestlers active in the mainland of America, “Sorakichi Matsuda” in the 1880s and “Mati Matsuda” in the 1920s. During the Ernesto Kojima period, he was fighting with El Santo in Mexico. In the United States, he studied with Karl Gotch to learn full-fledged wrestling techniques and was taught catch-as-catch-can, submission hold. German Suplex Hold, his biggest finishing technique, is said to have been worn under Gotch's guidance during this period.。 Kojima adopted his Hiro Matsuda identity while competing in the southern United States, inspired by earlier wrestlers Sorakichi Matsuda and Matty Matsuda. He initially debuted under his real name at Rikidōzan's Japanese Wrestling Association, but then left Japan to pursue wrestling in the Americas. Once in a while he would return to Japan, where he formed a tag team with Antonio Inoki that was only the outward reflection of the long-time friendship between the two men. Matsuda was the first Japanese to win a National Wrestling Alliance world singles title when he won the junior heavyweight championship on July 11, 1964, in Tampa, Florida by defeating Danny Hodge. He would win a second title in 1975 and lose it to Hodge. Matsuda challenge to NWA World Heavyweight ChampionLou Thesz on December 10, 1964 in Jacksonville, Florida, ended without a winner as a time limit draw. He had challenge to Thesz a few times. As a trainer, Matsuda was famous for being very stiff with his trainees to toughen them up and teach them to respect the business. He was very tough on a young Hulk Hogan; on his first day of training, Matsuda broke his leg. After Hogan healed, he came right back to Matsuda's school, looking to continue his training. Matsuda was so impressed by his display of "guts" that he trained him properly from that day on. He came to work in Jim Crockett Promotions in 1987 as a heel to participate in a feud between his disciple Lex Luger and Dusty Rhodes, plus wrestled a few matches on TV with Four Horsemenmanager James J Dillon acting as his manager. Matsuda was in Luger's corner. During the feud, he was billed as "The Master of the Japanese Sleeper," a sleeper hold. He famously locked Johnny Weaver, who was in Rhodes' corner, in the hold. The prolonged application of the hold caused Weaver to bleed profusely from the mouth. He later on worked briefly for World Championship Wrestling acting as the manager in early 1989 for the Yamasaki Corporation and then being involved in Terry Funk's stable, The J-Tex Corporation as their business agent from Japan. As was the case with Tojo Yamamoto, he was frequently made the manager or spokesman of Japanese wrestlers on excursion in the United States. In this role, he "introduced" The Great Muta on a World Championship Wrestling episode. His last match has against Osamu Kido at the age of 53 on December 26, 1990 in Hamamatsu, Japan. Lou Thesz, Nick Bockwinkel had wrestle in this day and Thesz has last match on his life too. Kojima died in 1999 in Tampa, Florida of colon cancer.
