World Boxing Council bantamweight champion Junto Nakatani of M.T Boxing Gym will defend his title for the first time against top-ranked Vincent Astrolabio of the Philippines on July 20 at Tokyo’s Ryogoku Kokugikan Sumo Arena as part of the triple world championship bouts dubbed ‘’Prime Video Presents Live Boxing 9,’ organizers said on May 31 at Tokyo Dome Hotel.

The 26-year-old Nakatani, a three-weight world champion, is undefeated in his 27 bouts, 20 by knockouts, while the 27-year-old Astrolabio has a record of 19 wins, including 14 KOs, against four losses.

Astrolabio lost by decision to Jason Moloney of Australia for the then vacant World Boxing Organization bantamweight title a year ago. Moloney lost the title to Japan’s Yoshiki Takei of Ohashi Boxing Gym on May 6 at Tokyo Dome.

Nakatani, currently in Los Angeles for an intensive training camp, told reporters at the hotel online, ‘’While my opponent is a hard puncher, I will fight at a distance of mine and want to knock him out.’’

Meanwhile, WBO super flyweight champion Kosei Tanaka of Soul Box Hatanaka Boxing Gym, Japan’s third boxer in history to win world titles in four different weight divisions, will take on 12^th-ranked Jonathan Rodriguez of Mexico for his first defense of the title he won in February.

The 28-year-old Tanaka has a record of 20wins, including 11 KOs, against a loss, whereas Rodriguez, also 28, has a 25-2-1 win-loss-draw tally with 17 KOs.

Top-ranked WBO flyweight Riku Kano of Taisei Boxing Gym will vie for the vacant WBO flyweight title with Anthony Olascuaga of the United States.

The 26-year-old Kano has a record of 22 wins, including 11 KOs, against four losses and two draws, while the 25-year-old Olascuaga, who is affiliated with Teiken Boxing Gym and has been training together with Nakatani in the U.S., has a 6-1 win-loss record with four KOs.

Besides, popular kick-boxer turned Tenshin Nasukawa of Teiken gym, currently ranked seventh in the bantamweight division by the World Boxing Association, will have a 10-round nontitle bout with the WBA’s fourth-ranked bantamweight Jonathan Rodriguez of the U.S.

Nasukawa has three straight wins, one by KO, since turning professional boxer in April last year, whereas the 25-year-old Rodriguz has a 17-2-1 win-loss-draw tally with seven KOs.
