Crazy appeared in NOAH for the first time in 2015 at the March 15 'Great Voyage in Tokyo' show teaming with Jonah Rock, Yoshinari Ogawa, and Zack Sabre Jr. in a losing effort to Captain NOAH, Taiji Ishimori, Muhammad Yone, and Katsuhiko Nakajima. Crazy replaced Takeshi Morishima in the 2015 Global Tag League and teamed with Mitsuhiro Kitamiya, marking Crazy's first heavyweight tournament in NOAH. The team failed to win a match and finished last in their block with zero points. From July 18 to August 5, Crazy took part in NOAH's Global Junior Heavyweight League. Despite winning his first three matches jumping out to an early lead in his block, Crazy lost his final three matches including a match on the final day against Bengala (played by former partner Ricky Marvin) which would have brought Crazy into at least a tie for first place in his block. Alas, Crazy finished in a four-way tie for third place with six points. In September, Crazy teamed with Hitoshi Kumano in the Global Junior Tag League marking Crazy's fourth consecutive appearance in the tournament. The pairing won only one match and finished last in their block with just two points. Crazy continued to work for NOAH throughout 2015 with his final appearance to date coming on December 4 where he teamed with Genba Hirayanagi to defeat Kumano and Ogawa.
