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.

Kenjutsu (剣術) is an umbrella term for all (ko-budō) schools of Japanese swordsmanship, in particular those that predate the Meiji Restoration. Some modern styles of kendo and iaido that were established in the 20th century also included modern forms of kenjutsu in their curriculum. Kenjutsu, which originated with the samurai class of feudal Japan, means "methods, techniques, and the art of the Japanese sword". This is opposed to kendo, which means "the way of the sword" and uses a bamboo sword (shinai) and protective armour (bōgu).
