Tenbin Nage
SubFamily天秤投げ(Tenbin-nage)
TraditionalTranslation: balance / scale-beam throw
Overview
Tenbin Nage (literally 'scale-beam throw') is an aikido throw that off-balances the opponent by hyperextending their elbow joint while levering against the shoulder, treating the opponent's straightened arm as a tenbin (the beam of a balance scale). [1],[2] The throw is mechanically distinct from kokyu nage and kaiten nage in that it uses joint engagement as the primary off-balance vector — the elbow extension creates pain compliance that drives the opponent forward and down. [1],[3] Tenbin nage is most commonly applied from sumi-otoshi or katate-dori entries and is closely related to Daito-ryu's ude-nobashi (arm-extension) techniques. [2],[4] In Yoshinkan curricula it is sometimes classified separately from the pure aiki throws because of the joint-engagement element; in Aikikai and Iwama-ryu it is taught as a canonical aikido throw at intermediate levels. [3],[4] The throw is named for the visual analogy: the opponent's straightened arm becomes the beam of a scale, with the aikidoka's lever applied at the elbow as the fulcrum and the wrist as the load. [1],[2]
History & Origin
Tenbin nage was systematised by Morihei Ueshiba and his senior students during the 1930s-1950s, derived directly from the ude-nobashi (arm-extension) lever techniques of Daito-ryu aiki-jujutsu under Sokaku Takeda. [1],[2] The naming references the Japanese word for a scale-beam (tenbin), with the opponent's straightened arm forming the beam of the balance. [1],[3] The throw appears in standard aikido curricula and was formalised in textbooks by Kisshomaru Ueshiba, Gozo Shioda, and Morihiro Saito in the 1950s-1970s. [3],[4]
Effectiveness
Tenbin nage is highly effective when the opponent's arm can be straightened — the lever mechanics are reliable. [1] It is harder to apply against opponents with bent-arm positions or against grappling-trained opponents who refuse to extend. [2] The throw is rarely seen in modern MMA in pure form, but the standing armbar that emerges from the same mechanics (ude-hishigi-juji-gatame from standing) is occasionally seen. [3] In Tomiki / Shodokan competitive aikido, tenbin nage appears in tanto-randori (knife defence randori). [2],[3]

Ratings
Risk of injury to the person this technique is applied to
High — joint engagement at the elbow can damage the joint if applied with full force or speed. The throw is typically practiced slowly with cooperative ukemi; in non-cooperative contexts the elbow hyperextension can produce hyperextension injury or even ligament damage

Notes
Tenbin Nage (balance/scale-beam throw) — uses the opponent's straightened arm as a lever, treating it as the beam of a balance scale. Joint engagement at the elbow distinguishes it from pure aiki throws like kokyu nage. Closely related to Daito-ryu's ude-nobashi.
Frequently Asked Questions
How does the Tenbin Nage work?
Tenbin Nage (literally 'scale-beam throw') is an aikido throw that off-balances the opponent by hyperextending their elbow joint while levering against the shoulder, treating the opponent's straightened arm as a tenbin (the beam of a balance scale).

The naming references the Japanese word for a scale-beam (tenbin), with the opponent's straightened arm forming the beam of the balance.
Is the Tenbin Nage legal in competition?
IBJJF: legal — Legal as throw; ADCC: legal — Legal; Unified MMA: legal — Legal as standing throw; sustained elbow hyperextension would qualify as a se…; IJF: legal — Legal as a throw entry; standing armbars (ude-hishigi-juji-gatame from standi…
How dangerous is the Tenbin Nage?
Danger rating 6/10. Moderate-high — joint engagement at the elbow can damage the joint if applied with full force or speed. The throw is typically practiced slowly with cooperative ukemi; in non-cooperative contexts the elbow hyperextension can produce hyperextension injury or even ligament damage
How do I set up the Tenbin Nage?
The standard setup chain: Receive Wrist Grab or Strike → Step Off-line → Extend and Straighten Uke's Arm → Apply Elbow Lever with Shoulder as Fulcrum → Project Forward and Down → Release Lever Cleanly.
How do I defend against the Tenbin Nage?
Standard counters include: Bend the elbow — refuse the straightened-arm position the lever needs / Release the gripped wrist before the lever forms / Pivot toward the thrower to relieve the lever angle / Stable grappling base with bent elbow positioning.
What are the variants of the Tenbin Nage?
Common variants: Standard tenbin-nage (Lever applied at the elbow with shoulder as fulcrum); Compact form (Yoshinkan) (Tighter lever with less travel; militarily-precise); Iwama-ryu form (Saito) (Emphasis on ki extension through the lever); Suwari-waza tenbin-nage (Kneeling form (formal training)).
How effective is the Tenbin Nage in competition?
Appears in Tomiki / Shodokan tanto-randori (knife defence) and toshu-randori. Generally non-competitive in Aikikai and Yoshinkan.
What are common mistakes when doing the Tenbin Nage?
Top errors to watch for: Applying the lever before the arm is straight — bent-elbow application produces an arm-twist, not a balance-beam throw / Using strength instead of leverage — tenbin nage works on lever mechanics; if force is required, the placement was wrong / Forgetting to off-balance forward — the throw needs uke's centre to be moving forward; static application fails / Rushing the lever — joint engagement requires sensitive timing; speed produces injury risk.
What are other names for the Tenbin Nage?
The Tenbin Nage is also known as Tenbin-nage, Tenbin Nage, Balance Throw, Scale-Beam Throw, Seesaw Throw.
