NEVER無差別級王座
NJPW returned to holding events in June, and Takagi was eliminated in the first round of the New Japan Cup by Sho. At Dominion in Osaka-jo Hall on July 17, Takagi defeated Sho to retain his NEVER Openweight Championship. On August 1, NJPW declared the NEVER Openweight 6-Man Tag Team Championship vacant, after Evil defected from "LIJ". Takagi defeated El Desperado at Sengoku Lord. At Summer Struggle in Jingu on August 29, Takagi lost the NEVER Openweight Championship to Minoru Suzuki. Takagi then competed in the 2020 G1 Climax, in the A Block. He ended the tournament with a final tally of 8 points (four wins and five losses) losing to Jay White, Jeff Cobb, Tomohiro Ishii, Kazuchika Okada, and Taichi, failing to advance to the tournament finals. However Takagi would get wins over Yujiro Takahashi, British Heavyweight Champion Will Ospreay, current rival Minoru Suzuki, and over eventual tournament winner Kota Ibushi.
