Beppu managed the Meiji University baseball team between 1989 and 1995 and won 4 championships. He also won the Meiji Jingu Tournament in 1995, became the first manager in the Tokyo Big 6 to bring on a female assistant (マネジャー), and made Jodi Haller the first female pitcher to pitch in Japanese college baseball in 1995.
During his tenure as manager, he's worked with players like Kenshin Kawakami, Yusuke Torigoe, Katsunori Nomura, and Takashi Ogasawara.
After his retirement in 1995, he was hired as director (総監督) of the Meiji University baseball team. In 2004, reports that Meiji University top prospect Yasuhiro Ichiba was taking money from NPB teams under the table broke and Beppu stepped down from his post to take responsibility.
