貞本義行
According to Yasuo Otsuka, who guided Sadamoto as a newcomer, there are only three people whom he regarded as more skillful than himself that he has met during his career. One of them is Yoshiyuki Sadamoto. The other two are Sadao Tsukioka who became a visual creator, and award-winning director Hayao Miyazaki. When Otsuka met the three men, he seems to have felt that he was taking off his hat to them at once. However, he thinks that only Miyazaki completely mastered a genuinely superior animation technique at present. He guesses, "A too excellent person might despair in the group work".
