Tomohiro Ishii
On January 5, 2019 at New Years Dash, Taichi pinned the IWGP Intercontinental Champion Tetsuya Naito in a ten-man tag team match between Suzuki-gun and Los Ingobernables de Japon, and challenging Naito for the title immediately afterward. The match was set at New Beginning in Sapporo on February 2, where Taichi was unsuccessful in capturing the title. In March, Taichi entered the 2019 edition of the New Japan Cup, defeating Tomoaki Honma in the first round before being eliminated in the second by Tomohiro Ishii. On May 3 at Wrestling Dontaku, Taichi defeated Jeff Cobb to win the NEVER Openweight Championship for the second time. The following night on May 4, Taichi would nominate Tomohiro Ishii as the next challenger for his title, with the match taking place on June 9 at Dominion. Ishii would win the match, ending Taichi's second reign as champion. Taichi would then make his G1 debut in the 2019 G1 Climax B block, where he finished with a record of eight points (four wins and five losses), notably defeating Tomohiro Ishii clean on the last night of block action. Following the G1, Taichi would enter a brief feud with Tetsuya Naito; him and DOUKI would lose to the team of Naito and Shingo Takagi at King of Pro-Wrestling (2019) via disqualification, and Naito defeated Taichi in a singles match at Power Struggle (2019). In the 2019 World Tag League, Taichi would once again team with Zack Sabre Jr. (unofficially dubbing themselves 'Dangerous Tekkers' and 'Godspeed You! Zack Emperor') and the duo ended the tournament with 18 points after 9 wins and 6 losses.
