All four boxers fighting for the March 31 world minimumweight championship fights in Nagoya cleared their weigh-ins at a hotel in the central Japanese city on March 30, thereby setting the stage for the event dubbed ‘’3150FIGHT vol.8’’ promoted by Kameda Promotion Co.

  The World Boxing Council’s champion Yudai Shigeoka of Watanabe Boxing Gym tipped the scales at the class limit of 47.6 kg (or 105 lbs), whereas sixth-ranked Melvin Jerusalem of the Philippines weighed in at 47.2 kg. The fight will serve as the main event of the 3150FIGHT.

  Yudai’s younger brother and his stablemate Ginjiro Shigeoka of the International Boxing Federation ruler weighed 47.5 kg. Both Yudai and Ginjiro Shigeoka are making their second defense of the titles, respectively.

Meanwhile, sixth-ranked minimumweight Jake Amparo of the Philippines, who hurriedly replaced his fellow countryman and ninth-ranked ArAr Andales as Andales suddenly cancelled his title challenge to Ginjiro Shigeoka earlier this week, citing he is in poor health, tipped the scales at 47.3 kg.

The scheduled-12 rounders will be held at Nagoya Congress Center.

 The undefeated Yudai Shigeoka has eight wins, five by knockout. While Jerusalem has a 21-3 win-loss tally with 12 KOs. Ginjiro Shigeoka has a record of 10 wins, eight by KO, with 1 no contest. Amparo has a 14-5-1 win-loss-draw tally with three KOs.

After the weigh-ins, Yudai Shigeoka, 26, told reporters, ‘’I am in good condition and will display what I have done during my training in the ring. I will show the kind of fight which will deserve the main event of the day.’’

The 30-year-old Jerusalem, who was a former World Boxing Organization minimumweight champion, said, ‘’I hope to earn a knockout victory. Since I am superior to my opponent on every front, I will prove that in tomorrow’s ring. I can’t very well lose since I have more experience.’’

  Ginjiro Shigeoka, 24, said, ‘’Since it will be my second title defense, I am determined to show how I have become stronger. Though my opponent has changed suddenly, it does not affect me at all because he (Amparo) is also an orthodox-style boxer. I hope I can knock him out.’’

  The 26-year-old Amparo said, ‘’I have to say thank you to all the people concerned for having chosen me (as a replacement for Andales). I have always kept my weight. I will show a good fight so that I can wrest the title.’’
