[1] (born December 16, 1966) is a Japanese professional wrestler, better known by his ring name, (also written MEN's Teioh). The English translation of his ring name, Terry Boy, is a homage to American professional wrestler Terry Funk.
Men's Teioh is a longtime mainstay of Big Japan Pro Wrestling (BJW) as well as a former competitor of Michinoku Pro Wrestling (Michinoku Pro). He is known as an original member of the group, Kai En Tai, which competed in Extreme Championship Wrestling (ECW) and the World Wrestling Federation (WWF) during the late 1990s. He was also briefly a member of the BWO while in Extreme Championship Wrestling, and appeared on the promotion's first PPV event Barely Legal in 1997.
Ōtsuka was trained to wrestle by Gran Hamada and Super Delfín. He debuted in September 1992 for Federación Universal de Lucha Libre (FULL) under his birth name, adopting the ring name "Men's Teioh" the following month. In March 1993, he began competing for the Iwate-based Michinoku Pro Wrestling promotion.
In February 1997, Kaientai DX travelled to the United States, facing Gran Hamada, Gran Naniwa, and The Great Sasuke at an Extreme Championship Wrestling (ECW) house show. The following month, they appeared on ECW's inaugural pay-per-view, Barely Legal, facing Gran Hamada, The Great Sasuke, and Masato Yakushiji.
In spring 1998, Kaientai returned to the United States to wrestle for the World Wrestling Federation (WWF). They made their in-ring debut on the May 11, 1998 episode of RAW is WAR, with Men's Teioh, Dick Togo and Sho Funaki facing 2 Cold Scorpio and Terry Funk in a handicap match. Kaientai feuded with Taka Michinoku, defeating Michinoku and Bradshaw in another handicap match at Over the Edge 1998, then losing to Michinoku and The Headbangers in a six-man tag team match at King of the Ring 1998. In August 1998, Michinoku joined forces with Kaientai. At SummerSlam 1998, Kaientai lost to The Oddities in another handicap match. Kaientai continued to appear with the WWF until late-1998.
In early 1999, Men's Teioh returned to Japan where he began wrestling for Big Japan Pro Wrestling (BJW). He appeared regularly with the promotion until 2015.
