Honda has served as the president of the Teiken Promotions and Teiken Boxing Gym in Tokyo, Japan since 1964.[2] Honda's motto "Pro Deo et Patria" implying "for God and Country" in Latin phrase is also that of Rikkyo University (also known as St. Paul's University) which Teiken Boxing Gym's founder Sadayuki Ogino and Honda graduated from.[3] At the age of twenty-two in 1970, Honda guided Masao Ōba to the world title, and later promoted the two of Mike Tyson's fights in 1988 and 1990.[5][4][2][3] He also realized the first world title tripleheader in Japan in 1998.[11]
While making contributions to those issues over years, Honda worked on the world title fights of Cesar Bazan (since the 1990s), Edwin Valero[2] et al. in the 2000s. In July 2007, he sent Jorge Linares to Las Vegas, Nevada, to successfully fight for and win his first world title.[15] He became the Japan's eighth world champion to be crowned across the sea.[16] In April 2010, Honda arranged the de facto unification match Hozumi Hasegawa vs. Fernando Montiel.[6] At that time, Montiel's WBO title was not at stake under the policies of the Japan Boxing Commission.[17] Hasegawa had wished to move to the featherweight division from more than two months ago, but he asked Honda to negotiate saying that he wanted to fight against Montiel even if his match fee would decline (Honda actually did not do it though).[6][18] The Japan's oldest surviving boxing journal Boxing Magazine placed that fight as the best card in Japan's boxing history as of April 2010.[19] Montiel received the second highest purse following Mike Tyson among the world champions fought in Japan.[20]
Honda-promoted Akifumi Shimoda, who was the tenth Japanese boxer to risk his world championship belt outside Japan, lost his world title at the Boardwalk Hall in Atlantic City in July 2011. Then Honda promoted the world title doubleheader headlined by Toshiaki Nishioka vs. Rafael Márquez at the MGM Grand Marquee Ballroom[21] in Las Vegas in association with Top Rank and Zanfer Promotions in October 2011.[22]Román González promoted by Honda[2] also made his United States debut on that card aired live on Fox Sports Net/Deportes,[23] Japan's WOWOW,[22] and Mexico's TV Azteca.[24] The realization of that card owes much to a trust relationship with Bob Arum,[25] the support of WOWOW which celebrated the twentieth anniversary at that time, and the popularity of Márquez.[26] Nishioka's defense in the United States was planned from around 2009.[27] Although Japan's professional boxing has some negative background, that was an aggressive overseas expansion in order to get higher status as a world champion.[28] Honda made Nishioka the first Japanese boxer who defended the world title in the United States.[21] That victory broke the sense of stagnation of Japan's professional boxing and gave it a hope.[29]
