On December 26, 2010, Orochi, Tadasuke's tag team partner, who had recently turned on LOV and joined the new Joker stable, which had taken over the spot as Osaka Pro's top heel group, approached Tadasuke after a match and handed him a letter. On January 29, 2011, Tadasuke turned on Black Buffalo and Tigers Mask, the last two remaining members of LOV, helping Kuuga and Orochi successfully defend the Osaka Pro Wrestling Tag Team Championship in the process. As a member of Joker, Tadasuke went on a win streak, which included singles victories over both Black Buffalo and Tigers Mask. On March 6, Tadasuke and Orochi wrestled Momo no Seishun Tag (Atsushi Kotoge and Daisuke Harada) to a double knockout in an Osaka Pro Wrestling Tag Team Championship number one contender's match. As a result, a three-way match was made for March 19, where Tadasuke and Orochi defeated Momo no Seishun Tag and defending champion, Big Guns (The Bodyguard and Zeus), to become the new Osaka Pro Wrestling Tag Team Champions. The following day, Tadasuke made an appearance for women's wrestling promotion Pro Wrestling Wave, defeating Sawako Shimono in an intergender match. The following month, Tadasuke, Hayata and Kuuga made it to the finals of the 12th Anniversary Six Man Tag Tournament, before being defeated by Black Buffalo, Naoki Setoguchi and Tigers Mask. Tadasuke's win streak eventually led to him unsuccessfully challenging Tigers Mask for the Osaka Pro Wrestling Championship on May 22. On July 18, Tadasuke and Orochi lost the Osaka Pro Wrestling Tag Team Championship to Momo no Seishun Tag in a three-way match, which also included the team of Takoyakida and Ultimate Spider Jr.
