Judo
The gentle way of Japanese judo emphasizes balance...
Judo, meaning "the gentle way," was founded in 1882 by Kano Jigoro as a physical, mental, and moral pedagogy. It originated from the older martial art of Jujutsu, which Kano redesigned to focus on safety and efficient energy use rather than lethal combat. Practitioners, known as judoka, progress through a ranking system denoted by colored belts (kyu) leading up to the black belt (dan). In competition, matches are won by achieving an ippon—a full point awarded for a decisive throw that lands the opponent on their back, or by a submission through pins, joint locks, or chokes. This focus on using an opponent's own force against them makes it a unique test of leverage and timing.
