Japanese fighter Kenpo Yamaguchi died on Saturday at the age of 70, his agency said.
The fighter, who won two Olympic gold medals in judo and karate in the 1970s, fought against the black belt of Kenpo Kiyotaka Morishita in a bout to be held at the famed Saitama Super Arena, according to his son, Kenpo Kamen.
Kenpo Yamakushi, the father of Japanese judo star Kenpo, died in hospital at the weekend in Yokohama, according his son.
He was in his early 60s.
Kenyo’s governor has called for the fighter to be buried in a private ceremony in the city’s Saitamasu shrine, but he has yet to announce his successor.
