Kendo is a modern Japanese martial art, descended from kenjutsu, that uses bamboo swords (shinai) as well as protective armor (bōgu). It began as samurai warriors' customary swordsmanship exercises, and today it is widely practiced within Japan and has spread to many other nations across the world.

Swordsmanship or sword fighting refers to the skills and techniques used in combat and training with any type of sword. The term is modern, and as such was mainly used to refer to smallsword fencing, but by extension it can also be applied to any martial art involving the use of a sword. The formation of the English word "swordsman" is parallel to the Latin word gladiator, a term for the professional fighters who fought against each other and a variety of other foes for the entertainment of spectators in the Roman Empire. The word gladiator itself comes from the Latin word gladius, which is a type of sword.
