He is popular for his fight style and unique personality, and has appeared in several television variety shows.

After graduating from middle school, Tatsuyoshi moved to Osaka to begin training, working part-time at restaurants to support himself.

Tatsyoshi won the Japanese amateur bantamweight championship at age 17, becoming a candidate for the Seoul Olympics.

He won the WBC World Bantamweight Title in his eighth professional fight in 1991, the fastest of any Japanese boxer (Nobuo Nashiro tied this record in 2006, winning the WBA Super Flyweight Title in his eighth fight).

Tatsuyoshi managed to continue his career, making a comeback in July 1994 in Hawaii, knocking out his opponent in three rounds.

Many began to believe he was no longer capable of fighting at the world level, and in November 1997, Tatsuyoshi challenged undefeated WBC Bantamweight Champion Sirimongkol Singwangcha, with the intent of retiring if he failed to win.

He changed his mind shortly afterwards and resumed his training, making a comeback fight on December 15, 2002, winning by TKO after more than three years of inactivity.

There are no plans for a next fight, but he still trains with his son, Jukiya, who wishes to follow his father into professional boxing.

Tatsuyoshi had suffered several serious injuries, and his management has expressed a desire to not see him take further damage, making it difficult for him to fight in Japan.
