Editing Bondage positions and methods (section)

====Shinju====
Shinju is a traditional Japanese breast bondage technique in which a rope is tied above, below and between the breasts, and also forms a halter over the shoulders and around the neck.<ref name=Pinkerton/> The term ''Shinju'' (from the [[Japanese language|Japanese]] 真珠 meaning [[pearl]]) is a euphemism to refer to the binding of female breasts. It has been popularly claimed that "shinju" is an authentic Japanese term for a "bikini harness". However, no such tie called a "shinju" is found in historic or present [[kinbaku]].<ref name="Shinju"/>

The basic or foundational kinbaku form of binding the arms and breasts is known as the [[Ushiro Takatekote]], which is to bind the arms behind (ushiro) the back in a box arm position (takate kote). This basic box arm tie, originally found in the [[samurai]] [[martial art]] of [[hojōjutsu]] (捕縄術) or Nawajutsu, (縄術) evolved into its erotic usage at the end of the 19th century and early 20th century, and is the foundation of most other kinbaku ties.{{sfn|Harrington|2007|pp=51–96}}
