  Yukio Mishima

  Confirmed

  Three independent chains agree: Japanese Wikipedia gives a detailed passage naming Nakayama Masatoshi as JKA chief instructor under whom Mishima trained from July 1967, with his own words to Nakayama quoted; the peer-reviewed JIRS study dates his start at the JKA to 1967; and Christopher Ross records the resulting grade as a first dan in Shotokan karate. No primary JKA register was consulted, but the convergence justifies confirmed.

  The Tatenokai article states that from autumn 1968 about ten core members began karate under Nakayama Masatoshi's instruction; Morita was a first-generation core member and later student president, but the article does not itemise the ten names and attendance was voluntary for members, hence probable rather than confirmed.
