GHCヘビー級王座
On November 20, 2015, Shiozaki returned to Noah, announcing he wanted to again wrestle in his original home promotion. His interview segment was interrupted by Minoru Suzuki, who offered him a spot in his Suzuki-gun stable. On November 26, Shiozaki defeated Mitsuhiro Kitamiya in his Noah return match. When Takashi Sugiura turned on Noah and joined Suzuki-gun on December 23, Shiozaki announced that he wanted to join the promotion in its battle with Suzuki-gun. Naomichi Marufuji, however, turned his offer down. On January 31, 2016, Shiozaki's tag team partner Yoshinobu Kanemaru turned on him and joined Suzuki-gun. At the end of the show, Marufuji, after losing the GHC Heavyweight Championship to Sugiura, finally accepted Shiozaki's help in the war between Noah and Suzuki-gun. On May 28, Shiozaki defeated Sugiura to win the GHC Heavyweight Championship for the third time. Shiozaki made his first successful title defense on June 12 against Suzuki-gun member Shelton X Benjamin. The following day, Shiozaki officially re-signed with Noah, ending his days as a freelancer. On July 30, Shiozaki lost the GHC Heavyweight Championship back to Sugiura. On December 3, Shiozaki and Maybach Taniguchi defeated K.E.S. (Davey Boy Smith Jr. and Lance Archer) to win the GHC Tag Team Championship. They lost the title to Kenoh and Masa Kitamiya on January 21, 2017. Shiozaki regained the title with new partner Atsushi Kotoge on August 26, losing it to Muhammad Yone and Quiet Storm on October 1.
