The purpose of this study was to examine the availability of the simplified tasks for the step-by-step practice of the judo throwing techniques. Participants were 12 college students who have attended the national College judo tournaments and the 16 principal throwing techniques were employed for the experiments. The simplified tasks of the throwing techniques were designed based on the opponent’s postures that were one knee and half sitting. Participants were asked to throw the opponents who assumed two kinds of the postures by 16 throwing techniques. 4 kinds of Taisabaki, which meant how to move legs, were used for the throwing trials. Binomial tests were conducted and results demonstrated that both the throwing tasks to one knee and the throwing tasks to half sitting were available for 9 throwing techniques. Neither the throwing tasks to one knee nor the throwing tasks to half sitting were available for 2 throwing techniques. The throwing tasks to one knee were not available, but the throwing tasks to half-sitting were available for 5 throwing techniques. Furthermore, appropriate Taisabaki was considered for each of the throwing techniques. The findings of this study would contribute to devise appropriate ways and means of judo practice for novices
