TOKYO, Japan (AFP) – Japanese boxing officials will hold an emergency meeting on Tuesday as the sport in the country faces intense scrutiny following the deaths of two fighters in separate bouts at the same event.

Super featherweight Shigetoshi Kotari and lightweight Hiromasa Urakawa, both 28, fought on the same card at Tokyo's Korakuen Hall on August 2 and died days later following brain surgery.

The Japan Boxing Commission (JBC), gym owners and other boxing officials are under pressure to act and will hold an emergency meeting on Tuesday.

They are also expected to have talks about safety next month, the local media said.

"We are acutely aware of our responsibility as the manager of the sport," Tsuyoshi Yasukochi, secretary-general of the JBC, told reporters on Sunday.

"We will take whatever measures we can."

Japanese media highlighted the risks of fighters dehydrating to lose weight rapidly before weigh-ins.

"Dehydration makes the brain more susceptible to bleeding," the Asahi Shimbun newspaper said.

That is one of the issues the JBC plans to discuss with trainers.

"They want to hear from gym officials who work closely with the athletes about such items as weight loss methods and pre-bout conditioning, which may be causally related (to fatalities)," the Nikkan Sports newspaper said.

In one immediate measure, the commission has decided to reduce all Oriental and Pacific Boxing Federation title bouts to 10 rounds from 12.

"The offensive power of Japanese boxing today is tremendous," Yasukochi was quoted by the Asahi Shimbun as telling reporters.

"We have more and more boxers who can start exchanges of fierce blows from the first round. Maybe 12 rounds can be dangerous."
