Kenjutsu (剣術) is the traditional Japanese art of the sword. It’s one of the four core martial arts (bujutsu) of pre-modern Japan. Two of the most prominent sword disciplines are kenjutsu and battōjutsu (抜刀術). The word “kenjutsu” is formed from ken (剣), meaning sword, and jutsu (術), meaning technique or method. Today, hundreds of martial arts schools around the world teach the principles of kenjutsu. But where did this sword art originate?
What Is Kenjutsu?
Kenjutsu refers broadly to the art of Japanese swordsmanship, tracing its origins back to the samurai era and feudal Japan. It emphasizes the technical and strategic use of the sword. Samurai warriors traditionally trained in “combat technique” — or Bujutsu — using wooden swords (bokutō or bokken), and occasionally real katanas. By the 19th century, bamboo swords (shinai) were introduced, making full-contact sparring more feasible.
The popularity of Kenjutsu declined during the mid-1800s due to the dissolution of the samurai class and sweeping societal changes in Japan. Still, it was revived toward the end of the 19th century, especially within the Japanese military and police forces.
Classical kenjutsu remains relatively rare outside Japan and is often considered a secretive warrior discipline. Modern Kenjutsu, however, is widely practised by martial arts enthusiasts interested in traditional styles. It’s most commonly taught using a bokken and is often integrated into other martial arts to introduce weapons training into empty-hand systems.
The Foundations of Kenjutsu
The sword has long been a central symbol in Japanese culture and warfare. It is one of the country’s three sacred imperial treasures (Mikusa no Kamudakara) — alongside the mirror (wisdom), jewel (compassion), and sword (valor). From 900 to 1300, swords saw limited battlefield use, as horse riding and archery were more dominant. But starting in the 1500s, swords became widely used in fortified towns and personal duels. Their portability made them a daily companion for warriors — even indoors.
Kenjutsu primarily focuses on one-on-one encounters. It includes techniques for defending against various weapons such as spears (yari), halberds (naginata), and staffs (jō). Whether against lances or arrows, kenjutsu techniques aim to give the sword-wielder a tactical advantage.
How Kenjutsu Is Practised
There are many kenjutsu schools with unique techniques and stylistic variations. Common skills include slashes, thrusts, strikes, blocks, feints, and coordinated footwork. Most techniques are trained as kata — structured movement patterns that simulate combat scenarios.
Generally, training emphasizes practical application based on situational awareness. Students learn to understand both their weapon and potential threats, along with body mechanics and movement strategy. While real combat is rare today, kenjutsu builds readiness for conflict through disciplined repetition.
Partner drills are often contact-free. Practitioners take turns attacking, defending, and rehearsing techniques without delivering full strikes, fostering control and precision in every movement.
