Answer
Yujiro Takahashi was Naito's partner in the tag team No Limit. The duo formed in 2005 and quickly rose through the ranks of New Japan Pro-Wrestling (NJPW). They won the IWGP Tag Team Championship twice and were known for their high-flying and innovative style. Takahashi and Naito eventually parted ways in 2010, but they remain close friends and have reunited on occasion for special matches.
