GHCジュニアヘビー級王座
Tanaka made his first appearance in NOAH after 15 years on September 5, 2017, and called for a shot at the GHC Junior Heavyweight Championship, but first defeated Hitoshi Kumano on October 1. He'd eventually get his shot on December 22, but was defeated by the defending champion Daisuke Harada. On March 11, 2018, he and Yoshinari Ogawa defeated XX (Hi69 and Taiji Ishimori) to win the GHC Junior Heavyweight Tag Team Championship, but, as Ishimori announced his departure the very next day, Ogawa opted to vacate the titles as he would not accept a title victory over someone focused mentally on leaving rather than focused on the match. This led to a tournament being set up to crown new champions, where Tanaka and new partner Hi69 defeated Ratel's (Hayata (wrestler) and Yo-Hey) in the finals on April 15 to regain the titles. On May 29, the two continued their battle against the stable by successfully defending the titles against Tadasuke and Daisuke Harada. On August 18, they successfully defended the titles by defeating Hayata and Yo-Hey once again. The pair continued their dominating run in a series of matches against some of Tanaka's regular career rivals - on September 2, the duo defeated Ikuto Hidaka and Takuya Sugawara from Zero1, the former of whom came up with Minoru as a rival in Battlearts. On November 25, Minoru and Hi69 won their fourth and final defense of the Junior Tag-Titles, taking on Tanaka's 20-year partner and enemy, Koji Kanemoto, and his partner Hiroshi Yamato. At Great Voyage on December 16, the duo's reign came to an end as they were defeated by The Back Breakers (Hajime Ohara &amp; Hitoshi Kumano). On March 10, 2019, Tanaka finally defeated Harada to win the GHC Junior Heavyweight Championship and complete his wins of the top three junior heavyweight championships in Japan (New Japan's IWGP, Noah's GHC, and All Japan's PWF) as well as Zero1's and Wrestle-1's titles.
