Junto Nakatani has benefitted from a years-long working relationship with Top Rank.
The Las Vegas-based promotional powerhouse is now along for the ride in an official capacity.
Teiken Promotions and M.T. Boxing Gym have entered a co-promotional agreement with Top Rank, all parties confirmed on Wednesday. The announcement came just four days after Nakatani (28-0, 21 knockouts) halted Vincent Astrolabio (19-6, 14 KOs) in the first round of their July 20 WBC bantamweight title fight in Tokyo.
