Shibari defined by Wikipedia 

Kinbaku (緊縛^?) translates to '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 (often jute, hemp or linen and generally around 6 mm in diameter, but sometimes as small as 4 mm, and between 7 – 8 m long). In Japanese, this natural-fibre rope is known as 'asanawa'; the Japanese vocabulary does not make a distinction between hemp and jute. The allusuon is to the use of hemp rope for restraining prisoners, as a symbol of power, in the same way that stocks or manacles are used in a Western BDSM context. The word shibari came into common use in the West at some point in the 1990s to describe the bondage art Kinbaku. 

Shibari (縛り^?) is a Japanese word that literally means "Decoratively Tie".

Shibari defined by photographer, rigger Hikari Kesho 

Shibari, more correctly known as Kinbaku is an ancient Japanese artistic form of rope bondage that has many styles and uses. It is related in style to other traditional Japanese arts such as Ikebana, Sumi-e (black ink painting) and Chanoyu (the tea ceremony). Among the many uses of Shibari are dynamic living sculpture, shared meditative practice, deep relaxation for flexibility of mind and body, expression of power exchange, and intimate erotic restraint.

In Shibari (the action of tying someone up) the Nawashi (rope artist) creates almost geometric patterns and shapes that contrast wonderfully with the female body's natural curves and recesses. Visually, the tight ropes and their texture provide a counterpoint to smooth skin and curves. The hard edges of the rope reinforce the softness of the body's graceful shape: the model is like a canvas, and the rope is paint and brush. This contrast is even emphasized by the use of Junoesque models, whose generous curves are squeezed by the ropes to create more pronounced shapes and shadows.

From antiquity to today, religious ceremonies in Japan involve ropes and ties to symbolize connections among people and the divine, as well as to delineate sacred spaces and times.
