Suburi (素振り, Naked/Unadorned Swing) is the ancient practice of training within swordsmanship undergone by virtually all Kenjutsu practitioners, although Samurai in particular are noted to their dedication to the practice. Along with timing and location, the physical strength and resolve behind one's sword stroke is critical to landing a proper attack. With thousands upon thousands of swings underneath their belt, Suburi enables every attack to maintain its optimal strength, for no swing is made with lackluster preparation.
