Renraku-waza / Combination Techniques
連絡技
A judo concept of smoothly chaining one technique into another, in which a failed or blocked throw attempt immediately exploits the opponent's reaction to launch a second throw.
Quick Facts
Definition
Renraku-waza in judo refers to a strategy of combination techniques, in which a judoka deliberately launches a first throw knowing the opponent will react in a certain, predictable way, and immediately exploits that reaction to chain into a second, usually more effective throw. A typical example is a combination where the attacker feints or genuinely attempts o-soto-gari, the opponent steps back or shifts weight forward to defend against it, and the attacker immediately uses this change in balance (kuzushi) to launch o-uchi-gari or sumi-gaeshi in the opposite direction. Renraku-waza is fundamentally different from kaeshi-waza (counter-techniques), because the attacker retains the initiative throughout, whereas kaeshi-waza arises from a defensive reaction to the opponent's attack. Mastering renraku-waza requires a thorough understanding of how specific throws typically disrupt an opponent's balance, and it is therefore traditionally taught only after a student has mastered individual throws separately through uchikomi drilling. In modern competitive judo, well-executed combinations are often the key to scoring ippon, since an opponent caught off guard by the second technique cannot react adequately in time.
