Beginning in September 2015, Otani downgraded himself back to the junior heavyweight division, proclaiming that the division had "lost its way" and "needed more heart". On September 23, he reformed his junior heavyweight team with Tatsuhito Takaiwa and defeated NWA International Lightweight Tag Team Champions Takuya Sugawara and Brother Yasshi to win the titles, the team's fourth tag team title overall and their first in 15 years. On October 11 Otani defeated Minoru Tanaka (who had defeated him and Takaiwa in 2000, along with Koji Kanemoto, to end their second IWGP junior tag reign) to win both the Zero1 International and NWA World Junior Heavyweight Championships. After three successful defenses, he lost the titles to Kotaro Suzuki on February 3, 2017.
