Junto Nakatani (26-0, 19KOs) and Alexandro Santiago (28-3-5, 14KOs) both made weight ahead of Santiago first WBC bantamweight title defense in Tokyo, Japan, a crown he won by defeating Nonito Donaire last year in Las Vegas. 

Nakatani challenges Santiago, aiming to become a three-weight world champion after previous title reigns holding the WBO’s flyweight and super flyweight titles. 

Chief support to the main event, Takuma Inoue (18-1, 4KOs), defends his title against former long-reigning IBF super flyweight champion Jerwin Ancajas (34-3-2, 23KOs) with the fight between the pairing serving as Inoue’s first defense of his WBA bantamweight title.

Both fighters made the weight, each tipping the scales at 117.75lbs. 

Former WBO three-weight champion Kosei Tanaka (19-1, 11KOs) faces Christian Bacasegua Rangel (22-4-2, 9KOs) in a fight for the vacant WBO super flyweight title.

Both Tanaka and Rangel weighed the same at 114.7 lbs.
