In 1975, the All Japan Kendo Federation (AJKF) developed then published "The Concept and Purpose of Kendo" which is reproduced below.
Concept Kendo is a way to discipline the human character through the application of the principles of the katana. Purpose To mould the mind and body. To cultivate a vigorous spirit, And through correct and rigid training, To strive for improvement in the art of Kendo. To hold in esteem human courtesy and honour. To associate with others with sincerity. And to forever pursue the cultivation of oneself. Thus will one be able: To love one's country and society; To contribute to the development of culture; And to promote peace and prosperity among all peoples.
Equipment The shinai is meant to represent a Japanese sword (katana) and is made up of four bamboo slats, which are held together by leather fittings. Kendōka also use hard wooden swords (木刀bokutō?) to practice kata. Kendo employs strikes involving both one edge and the tip of the shinai or bokutō. Protective armor is worn to protect specified target areas on the head, arms and body. The head is protected by a stylized helmet, called men (面), with a metal grille (面金men-gane) to protect the face, a series of hard leather and fabric flaps (突垂れtsuki-dare) to protect the throat, and padded fabric flaps (面垂れmen-dare) to protect the side of the neck and shoulders. The forearms, wrists, and hands are protected by long, thickly padded fabric gloves called kote (小手). The torso is protected by a breastplate (胴dō), while the waist and groin area is protected by the tare (垂れ), consisting of five thick vertical fabric flaps. Clothing The clothing worn under the bōgu comprise a jacket (kendogi or keikogi) and hakama, a garment separated in the middle to form two wide trouser legs. A cotton towel (手拭いtenugui) is wrapped around the head, under the men, to absorb perspiration and provide a base for the men to fit comfortably. Modern practice Kendo training is quite noisy in comparison to some other martial arts or sports. This is because kendōka use a shout, or kiai (気合い), to express their fighting spirit when striking. Additionally, kendōka execute fumikomi-ashi (踏み込み足), an action similar to a stamp of the front foot, when making a strike. Like some other martial arts, kendōka train and fight barefoot. Kendo is ideally practiced in a purpose-built dōjō, though standard sports halls and other venues are often used. An appropriate venue has a clean and well-sprung wooden floor, suitable for fumikomi-ashi. Modern kendo techniques comprise both strikes and thrusts. Strikes are only made towards specified target areas (打突-部位datotsu-bui) on the wrists, head, or body, all of which are protected by armor. The targets are men, sayu-men or yoko-men (upper left or right side of the men), the right kote at any time, the left kote when it is in a raised position, and the left or right side of the dō. Thrusts (突きtsuki) are only allowed to the throat. However, since an incorrectly performed thrust could cause serious injury to the opponent's neck, thrusting techniques in free practice and competition are often restricted to senior dan graded kendōka.
