キャンプ座間
Yamazaki instructed pupils of novice, intermediate and advanced levels at the headquarters of Kyokushin and the U.S. Army Camp Zama besides his own practice. He later said that it was good experience for him to instruct at Camp Zama as the pupils of the U.S. Army were larger than Japanese fighters. Several pupils measured over 200 centimeters in height and weighed over 90 kilograms, and practicing with these students led him to develop new ways to fight and knock out larger opponents.
