マサ斎藤
After embarking on an extended tour of Puerto Rican World Wrestling Council (WWC) in September 2010, Hirasawa adopted the new ring name Hideo Saito, as a tribute to Masa Saito and Hideo Nomo. His new gimmick saw Saito have (kayfabe) personality problems, in which he would find himself portraying a lot of characters besides himself. On 25 September, Saito would win his first championship when he won a battle royal for the vacant WWC Caribbean Heavyweight Championship and would lose it on 27 November. On 19 February, he also won the WWC Puerto Rico Heavyweight Championship and lost it on 26 March. In May 2011, Saito took part in NJPW's first tour of the United States, the Invasion Tour 2011. On 13 May in Rahway, New Jersey, he entered the tournament to determine the first ever IWGP Intercontinental Champion, losing to Yujiro Takahashi in his first round match.
