Joichiro Tatsuyoshi, known throughout Japan as “Naniwa no Joe”, is a Japanese former world champion who competed at bantamweight and super-bantamweight. Born in Kurashiki, Okayama, on May 15, 1970, he stood 5 ft 5 in and boxed from an orthodox stance. His professional record was 20 victories, seven defeats and one draw, with 14 wins by knockout. Few Japanese fighters of his generation commanded comparable public interest. His open, attacking style, low guard, and willingness to take punishment made him entertaining, though those same qualities contributed to several damaging defeats.
Tatsuyoshi was introduced to boxing by his father and moved to Osaka after leaving middle school, supporting himself with part-time restaurant work while training at the Osaka Teiken gym. He won the Japanese amateur bantamweight championship at 17 and was considered for the 1988 Seoul Olympics, finishing his amateur career with 18 wins and one defeat. His professional debut came in Osaka on September 29, 1989, when he stopped Sang Myon Choi in the second round. Less than a year later, in only his fourth contest, he knocked out Shigeru Okabe in four rounds to win the Japanese bantamweight championship.
After a ten-round draw with Abraham Torres and a points victory over Rey Paciones, Tatsuyoshi challenged Greg Richardson for the World Boxing Council bantamweight title on September 19, 1991. It was only his eighth professional appearance, equalling what was then the fastest route to a world championship by a Japanese boxer. Richardson was the more experienced man and an accomplished mover, but Tatsuyoshi pressed him relentlessly, worked to the body and gradually reduced the champion’s mobility. Richardson’s corner withdrew him after the tenth round, giving Tatsuyoshi the championship at the age of 21.
His first reign was interrupted before he could make a conventional defence. A torn retina discovered during training required surgery and kept him out of the ring for almost a year. During his absence, Victor Rabanales became interim champion. They met in Osaka on September 17, 1992, with Tatsuyoshi suffering the first defeat of his career when Rabanales stopped him in the ninth round. Tatsuyoshi recovered to defeat Rabanales on points in their July 1993 return, regaining interim recognition, but a detached left retina placed his career in jeopardy once again. He surrendered the title and underwent further treatment before returning in Hawaii in July 1994, knocking out Josefino Suarez in three rounds.
Tatsuyoshi’s popularity remained undiminished, and his December 1994 meeting with WBC champion Yasuei Yakushiji became one of the largest domestic boxing events staged in Japan. Tatsuyoshi entered as the public favourite despite his lengthy absences and limited professional experience. Yakushiji boxed with greater control, using short, accurate counters against the challenger’s wider attacks, and retained the title by majority decision after 12 rounds. Tatsuyoshi was later reported to have broken his left hand in the opening round, but he had completed the contest without making an issue of the injury.
The move to super-bantamweight produced victories in Japan and the United States, but the division also brought him into two difficult championship contests with Mexico’s Daniel Zaragoza. Tatsuyoshi challenged Zaragoza for the WBC title in Yokohama in March 1996 and was stopped in the eleventh round after a punishing fight. A second attempt in Osaka in April 1997 ended in a unanimous points defeat. By then there were reasonable doubts about whether Tatsuyoshi, weakened by eye trouble and repeated hard contests, could again succeed at world level.
He returned to bantamweight and received another opportunity against the unbeaten WBC champion Sirimongkol Singmanasak at Osaka-jō Hall on November 22, 1997. Tatsuyoshi had indicated that defeat would bring retirement, and he appeared to be behind during the first half of the contest. He continued attacking the champion’s body, however, and Sirimongkol began to slow. A sustained assault forced the stoppage in the seventh round, restoring Tatsuyoshi to the world championship more than six years after he had first won it. The victory, achieved after two serious eye injuries and three unsuccessful title challenges, was the defining result of his career.
Tatsuyoshi defended against Jose Rafael Sosa on points in March 1998. His next defence, against the unbeaten Paulie Ayala at Yokohama Arena, ended after six rounds when an accidental clash of heads left him unable to continue. Tatsuyoshi retained the title by technical decision. His reign ended on December 29, 1998, when Thailand’s Veeraphol Sahaprom knocked him out in the sixth round. No immediate rematch was arranged, but Tatsuyoshi went straight into a rematch in August 1999. Veeraphol controlled the exchanges more convincingly and stopped him in the seventh round. Tatsuyoshi announced his retirement afterwards, then reconsidered and resumed training.
More than three years passed before Tatsuyoshi returned in December 2002 to stop Saen Sor Ploenchit in six rounds. He outpointed Julio Cesar Avila in September 2003 but became inactive again after suffering a knee injury. Despite concern from his Japanese management over his previous injuries, he continued boxing abroad. He stopped Parakorn Charoendee in Thailand in October 2008, then lost his final contest to Sakai Jockygym at Bangkok’s Rajadamnern Stadium in March 2009. He did not fight professionally again, ending a career which had lasted nearly 20 years but contained only 28 contests.
Away from competition, Tatsuyoshi remained a familiar figure in Japan through television appearances and occasional boxing commentary. He also participated in public campaigns opposing bullying, drawing upon difficulties he had experienced as a child. His son, Juiki Tatsuyoshi, subsequently became a professional boxer, continuing the family’s association with the sport.
