Kendo is a martial art from Japan that deals with swordsmanship. However kendo is much more than just learning to make a correct strike. Kendo is about honing the human spirit to endure hardship, become better, stay humble, be more confident, and become a better person thorough the difficulty of training. Kendo is also a great way to develop new friendships over time.
Kendo has a number of etiquette rules to follow based on Japanese custom and is not trying ot teach one to fight with a sword so much as training in a particular style or fashion.
