during this time, ashihara was developing his own approach to the kyokushin curriculum he was teaching his students as well as adding additional movements and techniques that he had devised. his techniques involved using circular patterns to move outside of an opponent's attack and then to counterattack from a position of advantage. these techniques also involved parries and sweeps intended to use the opponent's momentum against him. he always stressed getting the maximum impact from a minimum amount of force. ashihara called these techniques, "sabaki." although many of these techniques were prohibited in kyokushin knockdown karate tournament rules, he taught them to his students, including ninomiya, so that they would be more effective, all-around karate fighters. many renowned karate students came to train at ashihara's dojo because of his reputation as an extremely effective instructor.
