Japanese-English shibari glossary: Newaza (寝技). Floor techniques with the body lying down or reclined, as opposed to seated techniques.

It is the umbrella term for techniques performed on or starting from the floor, understanding that in these techniques the body is “horizontal”, that is, lying down or reclined.

By contrast, suwariwaza (座り技) —or sit-jutsu— refers to floor techniques in which the body is “seated”.
