Yonekura Boxing Gym has so far brought up fifty champions including five world champions i.e. Kuniaki Shibata, Guts Ishimatsu, Shigeo Nakajima, Hideyuki Ohashi and Hiroshi Kawashima. The gym has provided a boxing television program Excite Boxing under the auspices of the TV Asahi on sky-A sports+ etc. In March 1995, Yonekura received the Distinguished Service Award in Sports from the education minister at the time, Kaoru Yosano.

Yonekura moved up in weight division to capture the OPBF bantamweight title in January 1960. In his second world title shot in the bantamweight division in May of that year, he lost to José Becerra via a split decision while being watched by 17,000 spectators at the Korakuen Baseball Stadium. From 1960 through 1961, he made an expedition to Mexico and fought four times in Tijuana and Mexico City, but was defeated in all those fights. After defending the OPBF title four times, he lost on points in his fifth defense in October 1962, and hung up his gloves.

His first world title shot against Pascual Pérez in the flyweight division, which was postponed three days due to rain, ended in a unanimous decision loss after being knocked down in the second round, in front of 9,000 spectators at the Tokyo Metropolitan Gymnasium in August 1959. However, as Yonekura had been highly expected to be the winner of it as a former Olympian, its audience rating was 88.0 percent. Yonekura was featured on the front covers of not only boxing-related such as (Japan's) Boxing Gazette, Puroresu & Boxing and Weekly Sports: Fight, but also various magazines such as Weekly Shōnen Magazine, Weekly Yomiuri Sports, Weekly Sankei Sports and Olympic Gahō, as a handsome superstar.

Yonekura made his professional debut under his real name Kenji Yonekura, written as 米倉 健治, in an eight-round bout in June 1958. Before his official debut, he made an exhibition match against the Japanese flyweight champion Sadao Yaoita as a welcome bout for the NBA's public relations manager. He was awarded with Japan's Fight of the Year and Technical Award in his debut year. His ring name was changed into 米倉 健志, pronounced the same, during his professional career. He captured the vacant Japanese flyweight title in January 1959.

He won on points over Phachon Muangson in the second round match, and lost on points to René Libeer in the quarterfinals. He also participated in the Seattle Golden Gloves in 1957, and compiled an amateur record of 71–7 (19 KOs) before turning professional.
