The Bokken (木剣) is a Japanese sword made of wood, mainly used for training in various martial arts, such as Kendo, Iaido, and Aikido. Its design emulates the shape and size of a katana, allowing practitioners to execute cutting and defense techniques without the risk associated with a sharp sword. The use of bokken not only focuses on the development of martial skills, but also on improving the posture, precision and spirit of the practitioner. It is often used in forms of practice known as kata, simulated duels that teach principles of combat and strategy. Its history spans centuries, being an essential instrument in the training of samurai and continues to be central to the modern practice of Japanese martial arts.
