鴨川ボクシングジム,

In 1969, Kamogawa opened the gym. By twenty years, the gym had produced two Japanese champions and one OPBF champion, Miyata Senior. The gym also had boxing manager, Haruhiko Yagi, trainer Shinoda, boxers Mamoru Takamura, Ichirō Miyata, Baron Kurita, Masaru Aoki, and Tatsuya Kimura, however, Baron soon quit due to Takamura. Takamura invited Ippo Makunouchi to the gym, and, after sparring with Miyata, he became a member of the gym. After a second spar between Ippo and Miyata, Miyata and his father left the gym so that Miyata could face Ippo in the professional ring. Years later, the gym got a JBC middleweight belt won by Takamura, and Naomichi Yamada became a member of the gym for a short time before leaving due to having to move out of town. A JBC featherweight belt was later won by Ippo. Manabu Itagaki joined the gym, and Takamura later won the WBC junior middleweight belt until he relinquished it to move a weight class up.

The gym then received the WBC middleweight belt by Takamura after he defeated David Eagle. Ippo had his JBC featherweight belt relinquished to move to the world stage. Takamura defeated world champion Richard Bison, making the gym acquire the WBA middleweight title.

After Ippo retired when he lost to Antonio Guevara, he became a trainer for the boxers, and Taihei Aoki and Kintarō Kaneda soon joined because of him. When Takamura defeated world champion Keith Dragon, the gym acquired the WBC super middleweight belt.
