柔道運動在我國已是眾所周知的運動之一，在日據時期就已傳入臺灣本土，而自今卻無人予以探究。因此，欲究明臺灣柔道運動發展的歷史，日據時期柔道運動的發展情形是必須先行探究的課題，此乃本研究的動機所在。本研究的目的在究明日據時期柔道運動發展的歷程，本研究使用歷史研究法，蒐集相關的史料，並以訪問柔道耆宿加以考證之。研究範圍為日據時期柔道運動之發展，時間為1895至1945為止。 日據時期柔道運動的傳入，是因為日人統治臺灣是利用「三段警備」、「保甲制度」等的警察制度維持治安，而日本警察本身就須具備柔道的素養，因而將柔道運動傳入臺灣。而更明確的傳入是在1911年柔道被列入為中等學校課外活動中，在學校的課外活動課程實施近二十年後，經過日本文部省審慎研究評估，終在1931年1月10日柔道被排定為中等學校必修課程，柔道運動正式在學校體育中成為必修運動項目之一，這個重大的轉變使得柔道運動在臺灣本土上紮下堅固的根基。
