Yukawaza 床技
"Floor technique": a Japanese term for rope tying done on the floor or a bed, used alongside newaza for floor work.
Andrea Ropes breaks yukawaza into yuka, floor or stage, and waza, technique or skill, which together give the sense of floor technique. Shibari Study’s glossary, writing it 床技, glosses it as tying on the bed, or floor work. Both glossaries cross-refer to newaza (寝技), a martial-arts word for ground techniques that Shibari Study notes is not specific to bondage; the same entry ties newaza to Yukimura Haruki as perhaps his favored way of tying. For the English term and its scope, see floor work.
