精力善用 seiryoku zen'yō Maximum Efficiency Minimum Effort

精力善用 is a rule for how you spend yourself, on the mat and off it. The rule is about energy, not effort: whatever you do, use your strength in the best way. Kept in the body, it makes the strongest body; kept in the mind, the best person; kept in work, good results. Whether it is for the dojo or for the rest of the day is yours.

精力善用 is composed of the words 精力 (read seiryoku) meaning "energy" and 善用 (read zen'yō) meaning "good use".

Kanō Jigorō made the best use of energy, 精力の最善活用, the first principle of judo in 1922, when he founded the Kodokan Cultural Society, whose creed leads from it to the common prosperity of mankind; the four-character 精力善用 is his own shortening, in the society's magazine by that November, and the characters had been ordinary Japanese since at least 1904.
