Kenjutsu (剣術, "sword technique") refers to the classical Japanese sword arts — koryu (古流, old-school traditions) — practiced by samurai (侍). Unlike Kendo, it uses wooden bokken (木剣) or blunted steel swords and focuses on partner kata (型) preserving battlefield techniques.
Kendo
Kendo (剣道, "way of the sword") is a modern Japanese fencing art using bamboo swords — shinai (竹刀) — and full armor — bogu (防具). Descended from kenjutsu, it emphasizes spirit (ki), sword technique, and body unity — ki-ken-tai-ichi (気剣体一致).
