Suspension is the pinnacle discipline of Japanese Shibari (Kinbaku), lifting human body mass partially or entirely airborne via load-bearing ropes and certified overhead rigging anchors. It unites advanced biomechanics, tension physics, and complete psychosexual surrender in zero gravity.
Severed from the earth, the suspended bottom loses spatial autonomy, entering a deep altered state known as rope space. The neurochemical flood of endorphins is extraordinary. The rigger must balance structural engineering with continuous vigilance over breath, skin tone, and neurovascular signals.
High risk of peripheral neuropathy: Radial nerve (arms), brachial plexus (armpits), and peroneal nerve (knees). Compression can induce temporary or chronic palsy (wrist drop / foot drop).
ALWAYS carry blunt-tip emergency trauma shears (EMT shears) on your body ready to cut load lines instantaneously.
Overhead anchor points must be structurally engineered and load-rated for at least 500–1000 kg dynamic shock load.
Perform frequent capillary refill tests (press nailbed – flush must return within 2 seconds).
Immediate descent is mandatory at the earliest sign of tingling, numbness, needle sensations, or cyanosis.
Multi-ply natural jute or hemp ropes (5.5–6mm) conditioned with camellia oil/beeswax, certified climbing carabiners (min 22 kN), suspension rings/pulleys, trauma shears, and high-density crash pads placed directly underneath.
Rigger and bottom must rehearse safety communication. In rope space, speech becomes sluggish – the rigger must initiate check-ins and demand quantitative ratings (1–10). Post-descent, keep the partner lying supine for several minutes to allow blood pressure stabilization.
