Glossary
Asanawa
The rope shibari runs on, and the one part you shouldn't try to save money on.
What is asanawa?
Asanawa (麻縄) is the Japanese name for natural-fiber rope, usually translated as “hemp rope.” It is the standard material for shibari. In practice it is often jute, sometimes real hemp or flax, in a loosely laid three-strand form around six millimeters thick.
| Japanese | 麻縄, literally “hemp rope”; the common translation also covers jute and flax in practice |
| Thickness | around 6 millimeters, sometimes 4 millimeters |
| Length | seven to eight meters per strand |
| Construction | loosely laid, three strands |
| Key property | it holds a knot and doesn’t slip, unlike smooth synthetic rope |
Why natural fiber, and what thickness?
It comes down to grip and to how the rope behaves under tension. The description of Japanese bondage lists jute, hemp, or flax of around 6 millimeters, sometimes 4 millimeters, in lengths of seven to eight meters, and says that the most commonly used rope is a loosely laid three-strand jute called asanawa.
That thickness isn’t an aesthetic choice. A thin rope cuts in, a thick rope won’t lay neatly. Six millimeters is the size at which the pressure spreads over enough skin while the knots still stay small.
What to watch for with asanawa
Rope thickness is a safety question, not a matter of taste. In Cureus, Khodulev and colleagues describe a 29-year-old woman who was fully suspended for 25 minutes on 6-millimeter jute rope and then fended off a foot drop, with a conduction block of 77.3 percent in the upper arm. In their patient group, the radial nerve was the affected nerve in 90 percent of the injured.
Their advice is technique, not material: spread the pressure evenly, spare the nerve pathways, and limit how long a full suspension lasts with regular checks. The rope is the carrier; the placement decides the damage.
If you’d like to experience ropework under guidance rather than figuring it out on your own, you can do that on a BDSM date.
