Kinbaku (緊縛?) means ‘tight binding’ Kinbaku-bi (緊縛美?) which literally means ‘the beauty of tight binding’.
Kinbaku is a Japanese style of bondage or BDSM which involves tying up the bottom using simple yet visually intricate patterns, usually with several pieces of thin rope (typically and generally between 5mm- 6mm in diameter, but sometimes as small as 4mm, and between 7m–8m long). In Japanese, this natural-fibre rope is known as ‘asanawa’; the Japanese vocabulary does not make a distinction between hemp and jute.
The allusion is to the use of rope for restraining prisoners, as a symbol of power, in the same way that stocks or manacles are used in a Western BDSM context.[1] The word shibari came into common use in the West at some point in the 1990s to describe the bondage art Kinbaku.
