I'll continue the discussion by quoting myself from a abstract I wrote a couple of years ago for class. It may not be 100% suited for your needs, and perhaps a tad "academic", but maybe as a starting point...?

When most people hear the word 柔道
jūdō, it brings to mind images of people in white pajamas: sweating, maybe shouting, and throwing each other to the ground with a loud 'thud'. Yes,
jūdō are those things, but both the name itself, as well as the philosophical and ethical musings from the arts' founder Jigoro Kano (1860-1938) all point away from the perceived violent nature of the art. Rather, one finds a desire to create something more than just a replacement for the German
Turnbewegungen (sometimes misnamed "Scandinavian gymnastics"), which he felt were movements without any relevance to real life. Specifically, he wrote that there were three "levels" or "purposes" to his
jūdō: a) 体育法
tai'iku-hō, or physical training; b) 勝負法
shōbu-hō, or martial training; and finally c) 修身法
shūshin-hō, which refers to moral or ethical training. This notion of combined personal, physical, and intellectual development are contained in the two maxims 精力善用
seiryoku zen'yō (also known as 精力最善活用
seiryoku saizen katsuyō; "best use of one's energy") and 自他共栄
jita kyōei, commonly translated as "maximum efficiency with minimum effort" and "mutual benefits" respectively.

After this, the abstract starts going in to areas not relevant for this discussion, so I cut it off here for now
