He came to work in World Championship Wrestling (WCW) in 1987 as a heel to participate in a feud between Lex Luger and Dusty Rhodes, plus wrestled a few matches on TV with Four Horsemen manager 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 (a renamed Four Horsemen) 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 (managed by Gary Hart) on a World Championship Wrestling episode.
Matsuda passed away on November 27, 1999.
In 2018, Matsuda was posthumously inducted into the WWE Hall of Fame as part of its Legacy Wing due to his contributions to the training of several top stars such as Hulk Hogan.
