Kenjutsu
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).
Niten Ichi-ryu
Niten Ichi-ryu ("Two Heavens as One") is the sword school founded by Miyamoto Musashi, the most famous swordsman in Japanese history. It specializes in using both long and short swords simultaneously.
Shinkage-ryu
Shinkage-ryu ("New Shadow School") was founded by Kamiizumi Nobutsuna in the 16th century. It is known for its sophisticated technique, the invention of the padded training sword (fukuro-shinai), and the concept of muto (no-sword).
