Bōgu



Bōgu (防具), properly called kendōgu (剣道具), is training armour used primarily in the Japanese martial art of kendo, with variants used for jukendo, naginatajutsu, and sojutsu.

History
During the Edo period (1603-1868) the use of real swords for training purposes was discouraged due to injuries, wooden practice swords in the form of bokken/bokuto and shinai were often used instead, and to further reduce injuries practice armour based on traditional samurai armor was developed, this practice armour was the basis for the modern bōgu.

Description and use
The word "bōgu" consists of two parts: bō meaning "protect" or "defend," and gu meaning "equipment" or "tool." A set of bogu has four components:
 * men (面): combined face mask and shoulder protectors (helmet);
 * kote (小手): hand and forearm protectors (gauntlets);
 * dō (胴): torso protector (breastplate);
 * tare (垂れ): groin and leg protectors (faulds).

A fifth component, sune-ate (脛当て) (shin protectors, or greaves), are worn by naginatajutsu practitioners.

The men protects the face, neck, and shoulders. It consists of a facemask with several horizontal metal bars running the entire width of the face, from the chin to the top of the head. To this is attached a long rectangular thick cloth padding that curves over the top of the head and extends to cover the shoulders. A throat protector is attached to the bottom of the facemask. The men is held in place with a pair of woven cords that wrap around the head and are tied at the back. The back of the men is left open for ventilation and the back of the head is unprotected. The target areas of the men are the centre top, and upper left and right sides for cutting strikes and the centre of the throat protector for a thrust.

The kote are mitten-like gloves. They were designed expressly for kendo. While appearing to be cumbersome, enough mobility is allowed to grip the shinai in a comfortable, powerful, and firm way. Kote for naginatajutsu practitioners have a singulated index finger and thumb to better facilitate the rapid shifting of the hands along the length of the naginata's shaft. Naginata kote have a little less padding than those used for kendo. In the past, kote were often made with fully articulated fingers. This is rarely seen today as there can be a safety issue with snagged fingers. A special heavily padded design known as oni-gote (鬼小手) are used by some koryu, most notably Itto-ryu. The target area is the wrist portion of each kote.

The main component of the dō is the gently curving stomach and chest protector. The modern form has a pronounced bulge to help direct the force of strikes away from the soft areas in the middle of the torso. Lacquered bamboo is traditionally used although lacquered paper 'fibre' (frequently misidentified as fiberglass) or moulded plastic are used for less expensive dō. The dō is supported from the shoulders by two diagonal ties and is restrained at the small of the back with another set of ties. The target areas of the dō are the two lower sides for a slashing cut to the stomach. The top half of the dō is a valid target for a thrust in naginata. In the past, this was also a valid target for a thrust in Kendo.

The tare is a thick cloth belt that wraps around the waist and ties under the front flap in front of the groin. Sturdy cloth covered flaps hang from the belt to protect the upper legs and groin. The flaps run along half of the belt's length, which should be positioned over the front half of the body. The centre flap is usually covered with a name tag—zekken (ゼッケン) or nafuda (名札)—that identifies the name of the wearer and the dojo or country he/she represents. There is no target point on tare, it is for protection against off-target and accidental strikes.
