Background & Study Aim: There is a picture that was sketched where a little lady controls a big man who breaks his balance with a forefinger. The three explanations in previous documents are not always clear or complete by the interpreters. The first technique of the Itsutsu-no-kata and the lady?s skill were considered to include the soft type of atemi-waza. The aim of this study is to clarify the mechanism of the soft type of atemi-waza that Kenji Tomiki had studied since 1942.
Material & Methods: This study examines a few points that are made in three explanations from the perspective of Seiryoku Zenyo of judo after introducing them precisely, while referring to the Itsutsu-no-kata and Tomiki?s theory.
Results: (1) The woman?s technique shown in the picture has a close relationship with a kind of soft type of atemi-waza. (2) The big man who puts his weight onto his right foot temporarily retreats with his left foot as a result of her continuation of the push and then will retreat his right foot in an attempt to compensate for the acceleration, causing him to fall down. (3) When the big man recovers stability, it is necessary for her
to break the man?s balance onto the heels of both feet while maintaining the power to push her palm even if the man?s feet have adapted to his movement.
Conclusion: This study shows that the skill of the lady?s postures of right and left, unsoku, tegatana, balance breaking, and soft type of -atemi are indispensable for her to continue to control the big man, and is acquired by a relative exercise and accomplished depending on the movement of the partner, because fighting forms of the exercise vary greatly.
