Ryota Hama
The 2009 Real World Tag League win earned Muto and Masakatsu Funaki, a title match for the World Tag Team Championship against Minoru Suzuki and Taiyo Kea on January 3, 2010, which Muto and Funaki won. On January 30, Muto, under his Great Muta gimmick, made a special appearance for Pro Wrestling Guerrilla in Los Angeles, California, during the WrestleReunion 4 weekend, teaming up with Kai in a match, where they defeated the team of Joey Ryan and Scott Lost. On March 9, Muto and Funaki were forced to vacate the titles due to Muto going through a reconstructive knee surgery that kept him out of the ring for the rest of the year. Muto returned to All Japan as Great Muta at Pro-Wrestling Love in Ryogoku Vol.10 in August, where he lost to Kenso in a Tables, Ladders and Chairs match. On September 10, Muto faced his former tag team partner Masakatsu Funaki in a special return match, which ended in a thirty-minute time limit draw. On October 24, Muto unsuccessfully challenged Kaz Hayashi for the World Junior Heavyweight Championship. On December 12, Muto and Kannazuki lost the F-1 Tag Team Championship to Ryota Hama and Koriki Choshu after a four-year reign.
