The wakizashi, a shorter companion sword to the katana, became standard for samurai in Edo-period Japan around 1600. This weapon was used not only in battle but also in duels and as a means of self-defense in urban settings like Kyoto. The wakizashi's significance lies in its role within the samurai code and its representation of the warrior class's values and traditions.

Wakizashi embody samurai ethics in haiku and chanoyu-related literature, inspiring Western adaptations exploring duality and discipline.
