Sawai also found his own martial art named Taiki Seisei Kenpo, called Taikiken for short.
Initially, Wang had principle of not accepting foreign students, but saw Sawai's enthusiasm as earnest and took him as his pupil.
Initially, the style was to be called Taiseiken, but with permission from Wang Xiangzhai, he added a single letter "ki", and founded Taiki Seiseikenpo (Taikiken).
He also interacted with Dutch Judoka Anton Geesink, when he was involved with Kyokushinkai and learned Taikiken from Sawai.
Hajime Kazumi, while not directly taught by Sawai, integrated the elements of Taikiken into his Kyokushin fighting style.
