Battojutsu (alternatively known as iaijutsu) is the combative means of quickly deploying and using the Japanese sword. This is a separate art containing its own techniques that compliment kenjutsu training. The art of deploying the sword from its sheath was critical in engaging the enemy, and was developed and utilized in both aggressive and defensive actions in a wide variety of circumstances.

The techniques of rapidly unleashing and cutting with a sword are extremely sophisticated and intense in nature. Therefore, students begin their training in battojutsu using unsharpened metal training swords. After proficiency is gained in the kihon (fundamentals), practitioners then incorporate shinken (live blades) into their practice. This helps to hone the practitioner’s mental and physical capabilities into one integrated unit, which allows for the most efficient method of employing the sword.
