In the Japanese tradition, the relationship between rope and knot is so deep. Gifts are wrapped and tied in Furoshiki is normal in Japan.”Shibari” simply means “to tie”. The contemporary meaning of Shibari describes an ancient Japanese artistic form of rope bondage.

The origin of Shibari comes from Hojo-jutsu, the martial art of restraining captives. In Japan from 1400 to 1700, while the local police and Samurai used Hojo-jutsu as a form of imprisonment and torture, the honor of these ancient Samurai warriors required them to treat their prisoners well. So, they used different techniques to tie their prisoners, showing the honor and status of their captured prisoner.

In the late Edo era(1603-1867), bondage was used to torture women who were taken prisoner of war or girls of rival masters. Tying has often turned into forms of humiliation in very open spaces and squares.
Beginning in the 1800s, high social class members connected nude women with soft and degrading positions, drawing their pictures and using them sexually in the eroticisation of tying. Wealthy and noble people were also invited to these events in later periods. These invitations and events were called Komon Sarashi Shibari. Very rare examples of these drawings appeared in Ukiyo-e (17th century erotic wood print) collections.

The aesthetic arrangement of ropes and knots on the model’s body in Shibari rigging emphasises characteristics like sensuality, vulnerability, and also strength. The positioning of knots in appropriate places stimulates pressure points on the body, very similarly to acupuncture techniques and Shiatsu, a form of Japanese massage. Some believe a shibari experience also stimulates Ki energy flow and transfer.
Shibari rigging induces physiological conditions known as “sub space” and “top space”, which are similar to the “runners high” experienced by athletes. A Shibari experience results in an increased level of endorphins and other hormones, creating a trance-like experience for the bottom/model and an adrenaline rush for the Top/rigger. When a shibari scene is performed with appropriate ambience, these effects are actually visible in the face of the model. The term “rope drunk” is sometimes affectionately used to describe the euphoric condition of the model after a shibari experience.
