Kinbaku, sometimes rendered kinbaku-bi ('the beauty of tight binding'), is a Japanese term for rope bondage. In Western usage the word is often invoked to foreground the intimate, expressive and aesthetic aspects of the practice.

Different schools and teachers draw the line between shibari and kinbaku in different places; both terms remain in active use. This practice generally requires advanced education, informed consent, appropriate risk awareness and should not be approached without adequate knowledge and preparation.
