In February 2008, Naito formed a tag team with fellow rookie Yujiro Takahashi called "No Limit". In March, the two went to fifteen-minute time limit draws with former IWGP Junior Heavyweight Tag Team Championship teams such as Koji Kanemoto and Wataru Inoue, and Minoru and Prince Devitt, and Yujiro pinned veteran Super Strong Machine in a trios match. All of this led to a junior tag title challenge for the duo, facing Machine's Legend stablemates Jyushin Thunder Liger and Akira, in which No Limit came up short when Akira pinned Tetsuya. Yujiro would then participate in the ongoing feud between New Japan and Pro Wrestling Zero1, teaming with Koji Kanemoto and Manabu Nakanishi in two separate tag team matches, losing to Zero1's Masato Tanaka and Tatsuhito Takaiwa in the former, and defeating Takao Omori and Osamu Namiguchi in the latter.
