Sangu is the term for the three armour components that protected the extremities of the samurai class of feudal Japan.
Traditional Japanese armour had six main components (hei-no-rokugu, roku gu, or roku gusoku), the dou or dō (chest armour), kabuto (helmet), mengu (facial armour), kote (armoured sleeves), sune-ate (shin armour), and the hai-date (thigh armour). [1] [2] [3] The sangu was composed of the suneate (shin armour), kote (armored sleeves), haidate (thigh armour). These armour components were a combination of a cloth backing and various types of armour that was attached to the cloth backing. On an original authentic suit of Japanese armour (gusoku) the cloth backings, edgings, decorations etc. and the armour elements would all be matching to each other. [4]
Kote (籠手, armored sleeves). These sleeves are usually of textile material, often silk brocade, padded, laced with the small cords upon the inside of the arm and covered with mail, small metal plates of various size and shape, or quilting having small plates of metal or hide sewn inside each quilt. Gauntlets (tekko), or covers of metal plates for the back of the hand, are attached to the kote. There are many varieties of kote such as ubu-dzutsu, bishamon (having sode (shoulder guards) attached, shino-odatsugi, ainaka-gote, and others including aigote (in which the two sleeves are connected), kigote which is a general term for the kote extended or completed by the addition of erisuwari (padded collar), kata-ate (shoulder pads) and wakabiki (armpit protectors), jubangote ( kote with shirt), tominaga kote (named after its inventor), kusari kote (chain armour), kote haramaki ( kote that cover even the belly), kogusoku-kote (armor-like kote ), han kote (half kote gauntlets). [5]
Suneate (臑当, literally shin guards ) are a type of armoured shin protection worn by the samurai class and their retainers during the feudal era of Japan. Suneate first started being used in the 12th century. The suneate most commonly consisted of vertical armour plates of iron or leather connected by either hinges or mail armour (kusari), suneate could also be made almost entirely of mail. The plates were usually attached to a cloth backing which had cloth straps that were used to tie the suneate to the lower leg. There is usually a leather guard abumi-zure attached to the inner side of the place that will come into contact with the stirrup when riding. The more ancient examples of these shin-guards are seen as plates, often with rather large knee guards attached. When worn the abumi-zure of the suneate will be placed toward the inner side of the leg. [6] [7] [8]
Haidate (佩楯, thigh armour) was a type of cloth apron with various types of armour attached to the cloth backing. [9]
Chain mail is a type of armour consisting of small metal rings linked together in a pattern to form a mesh. It was in common military use between the 3rd century BC and the 16th century AD in Europe, and longer in Asia and North Africa. A coat of this armour is often called a hauberk, and sometimes a byrnie.
Bōgu, properly called kendōgu, is training armour used primarily in the Japanese martial art of kendo, with variants used for jūkendō, tankendo, and naginata.
Ashigaru were infantry employed by the samurai class of feudal Japan. The first known reference to ashigaru was in the 14th century, but it was during the Ashikaga shogunate that the use of ashigaru became prevalent by various warring factions.
Lamellar armour is a type of body armour, made from small rectangular plates of iron or steel, leather (rawhide), or bronze laced into horizontal rows. Lamellar armour was used over a wide range of time periods in Central Asia, Eastern Asia, Western Asia, and Eastern Europe. The earliest evidence for lamellar armour comes from sculpted artwork of the Neo-Assyrian Empire in the Near East.
A greave or jambeau is a piece of armour that protects the leg.
Kabuto is a type of helmet first used by ancient Japanese warriors which, in later periods, became an important part of the traditional Japanese armour worn by the samurai class and their retainers in feudal Japan.
Outside of Japan, a Shitagi, a type of shirt worn by the Samurai class of feudal Japan when they were wearing full armour.
A brigandine is a form of body armour from the Middle Ages. It is a garment typically made of heavy cloth, canvas, or leather, lined internally with small oblong steel plates riveted to the fabric, sometimes with a second layer of fabric on the inside.
Scale armour is an early form of armour consisting of many individual small armour scales (plates) of various shapes attached to each other and to a backing of cloth or leather in overlapping rows. Scale armour was worn by warriors of many different cultures as well as their horses. The material used to make the scales varied and included bronze, iron, steel, rawhide, leather, cuir bouilli, seeds, horn, or pangolin scales. The variations are primarily the result of material availability.
Kyahan are cloth leggings which were worn by the samurai class and their retainers in feudal Japan. In Japanese, the word is also used for Western soldier's gaiters.
Auxiliary armour in a set of Japanese armour are optional pieces worn by the samurai class of feudal Japan in addition to the traditional six armour components.
The proofing of armour is testing armour for its defensive ability, most commonly the historical testing of plate armour and mail (armour). In the early Middle Ages, armour would be classified by the blows it could withstand, being certified as proof against swords, axes, and arrows. As firearms emerged as battlefield weapons, armour would be tested against them, as well, from which came the modern term "bulletproof".
Mail and plate armour is a type of mail with embedded plates. Armour of this type has been used in the Middle East, North Africa, Ottoman Empire, Japan, China, Korea, Vietnam, Central Asia, Greater Iran, India, Eastern Europe, and Nusantara.
Scholars agree that Japanese armour first appeared in the 4th century, with the discovery of the cuirass and basic helmets in graves. During the Heian period (794-1185), the unique Japanese samurai armour ō-yoroi and dō-maru appeared. The Japanese cuirass evolved into the more familiar style of body armour worn by the samurai known as the dou or dō, with the use of leather straps (nerigawa), and lacquer for weatherproofing. Leather and/or iron scales were also used to construct samurai armours, with leather and eventually silk lace used to connect the individual scales (kozane) of these cuirasses. In the 16th century, Japan began trading with Europe, during what would become known as the Nanban trade. This was the first time matchlock muskets were imported, and as they became mass-produced domestically, samurai needed lighter and more protective armour. As a result, a new style of armour called tosei-gusoku (gusoku), which means modern armour, appeared. When a united Japan entered the peaceful Edo period, samurai continued to use both plate and lamellar armour as a symbol of their status.
Kikko are small iron or hardened leather, hexagon shaped armour plates used in the construction of Japanese armor worn by samurai and ashigaru of feudal Japan.
Tatami (畳具足), or tatami gusoku and gusoku, was a type of lightweight portable folding Japanese armour worn during the feudal era of Japan by the samurai class and their foot soldiers (ashigaru). The Tatami dō or the tatami katabira were the main components of a full suit of tatami armour.
Dō or dou (胴) "breastplate, cuirass" is one of the major components of Japanese armour worn by the samurai and ashigaru or foot soldiers of feudal Japan.
Kusari gusoku (鎖具足) is the Japanese term for mail armour. Kusari is a type of armour used by the samurai class and their retainers in feudal Japan. When the word kusari is used in conjunction with an armoured item it usually means that the kusari makes up the majority of the armour defence.
Karuta was a type of armour worn by samurai warriors and their retainers during the feudal era of Japan. The word karuta comes from the Portuguese word meaning "card", (carta) as the small square or rectangular plates that compose the armour resemble traditional Japanese playing cards.
