Kendo is a traditional Japanese martial art that originated from the samurais fighting methods in feudal Japan. It is a form of fencing that uses a two-handed wooden sword called a shinai and protective armor. Kendo is not solely about winning but also respects good manners and nurtures a strong spirit. The All Japan Kendo Federation developed and published "The Concept and Purpose of Kendo" in 1975, which outlines the following purposes of Kendo:

• To mold the mind and body.
• To cultivate a vigorous spirit.
• To strive for improvement in the art of Kendo.
• To hold in esteem courtesy and honor.
• To associate with others with sincerity.
• To forever pursue the cultivation of oneself.
• To love ones country and society.
• To contribute to the development of culture.
• To promote peace and prosperity among all people.

Kendo is widely practiced in Japan and has spread to many other nations across the world. It is practiced wearing a traditional Japanese style of clothing, protective armor, and using one or, less commonly, two shinai. Kendo matches take place in an area 9 to 11 meters square, and contestants wear traditional attire and protective gear. Kendo players are called "Kendoka" or "Kenshi".
