Founded by Kamogawa Genji years after his retirement, the gym is two stories with a basement. The first floor and basement serve as training areas while the second floor contains Kamogawa's office. Both the first floor and basement also contain boxing rings in them. By the start of the series, the gym had produced two Japanese champions and one OPBF champion (Miyata's father). At present, one member holds a championship: Takamura Mamoru (WBC & WBA Middleweight). Previously Makunouchi Ippo was the JBC Featherweight champion.
