The 12 Precepts of Jūdō – Kanō Jigorō 1930
(updated 10.6.2022) This rare text by Kanō shihan (master) is very indirect and complex. The below is simply a truncated paraphrasing of that list in an obscure early Showa era book.
The ‘practice’ mentioned is 修行 shugyō, which the excellent www.jisho.org defines as:
1. ascetic practices (Buddhist term)
2. training; practice; discipline; study
3. Wiki: Shugyo – Sādhanā (Sanskrit साधन, Tibetan སྒྲུབ་ཐབས་, druptap; Wylie sgrub thabs), literally “a means of accomplishing something” is ego-transcending spiritual practice. It includes a variety of disciplines in Hindu, Sikh, Buddhist and Muslim traditions that are followed in order to achieve various spiritual or ritual objectives.
Seiryoku zenyō Jita kyōei are the two phrases of Kanō shihan’s jūdō philosophy,
typically translated as “Best use of energy / Mutual benefit” (see postscript)
