[Machine Translation] "The Essence of Swordmanship: Transmitting Ancient Martial Arts to the Modern Age," Volume 1 Now on Sale! The True Nature of Ancient Martial Arts. Ancient swordsmanship seeks to achieve a high level of physical and mental coordination based on the premise of a sword that cuts the moment it touches." This video presents a commentary and demonstration of the Omote Chu-tachi Rokuhon" (Six Forms of the Middle-Length Sword), which embody both the fundamentals and the essence of Master Tetsuzan Kuroda s techniques. These techniques convey the true nature of ancient martial arts rooted in Muzashi" (no feet), Ukemi" (floating body), the vanishing body," and standing at a single point" and are the very foundation of these ancient traditions. Why do ancient sword techniques require a half-body stance and a lowered center of gravity? Why are both elbows extended? Why is the sword rotated? And why does a speed invisible to the eye emerge? These questions can only be understood through the embodiment of physical movements that are simultaneously the greatest and the shortest, the smallest, the fastest, and the strongest.
