Daiwa Ryu jujutsu, like many traditional Japanese martial arts, is taught in part through the repetition of a series of preset techniques. This is the martial art equivalent of practising your musical scales; it's not designed to be a realistic application of the technique, but instead to commit the details to muscle memory.
The technique lists presented here are intended as a memory jogger for existing students. You won't be able to lean jujutsu just be reading them!
