摘要：If a specific judo player has two special techniques at one time, it can be said that these two techniques have something common by some factors. If this relationship can be applied to other players, it is generally considered that a player with one of these two techniques as his specialty has the possibillity of mastering the other technique as his other specialty. From this point of view, the similarity of special techniques was defined, and the statistical structure and classification of throwing techniques of judo, different from the traditional ones were discussed. A questionnares survey was conducted to national team members and the statistical structure of special techniques was abstracted by applying nonmetric multidimensional scaling to the acquired similarity matrix. The following conclusions were obtained: (1) Among techniques studied here, "ouchigari", "ippon-seoinage", and "ostogari" have a genral characteristic, and many players use them as their special techniques. Therefore, these techniques are assumed to be easilly mastered by many players as their special techniques. (2) The following techniques are similar to each other: "osotogari" and "uchimata", "seoinage", "ippon-seoinage" and "taiotoshi" and "ouchigari" and "kouchigari".
