Tsubame Gaeshi is a technique from the martial art of Kendo, which involves a swift counterattack. The name translates to "swallow return," inspired by the way a swallow bird swiftly changes direction in flight. This technique is executed when an opponent strikes, allowing the practitioner to evade the attack and immediately counter with their own strike. The effectiveness of Tsubame Gaeshi lies in its timing and precision. It requires the practitioner to anticipate the opponent's move and respond almost instantaneously. Mastering this technique can significantly enhance a Kendo practitioner's defensive and offensive capabilities during a match.
