Following that fight it did seem like Igarashi had made up his mind about his future, but it wasn't until he took part in a press conference that he fianlly confirmed that his career was over, and that he was retiring.
After the fight Igarashi's blog was updated saying thanks to those who have supported him over his long career. It was then stated that Igarashi had considered retirement a number of times, mainly due to the injuries that he has suffered in recent years.
At the press conference Taguchi spoke about feeling the will power of Kimura and that nothing he did really worked. He stated he had no regrets about his career and seemed happy to have ended his career on the big stage of a world title fight.
During his career Igarashi claimed the Japanese Flyweight title, the WBC Flyweight and the Linear title. He wasa highly regarded amateur prior to making his professional debut and one of the key figures of the Teiken gym, though at 33 his career was likely coming to an end based on age on retirements, even if he had managed to some how beat Kimura.
