Japanese armour

Armour in Japan has a history that goes back as far as the 4th century.^[1] Japanese armour developed enormously over the centuries since its introduction to the battlefield and warfare.

History

Japanese armour is thought to have evolved from the armour used in ancient China and Korea.^[1] Cuirasses and helmets were manufactured in Japan as early as the 4th century.^[1] Tankō, worn by foot soldiers and keikō, worn by horsemen were both pre-samurai types of early Japanese cuirass constructed from iron plates connected together by leather thongs.

During the Heian period (794-1185), the Japanese cuirass evolved into the more familiar style of armour worn by the samurai known as the dou or dō. Japanese armour makers started to use leather (nerigawa) and lacquer was used to weather proof the armor parts. By the end of the Heian period the Japanese cuirass had arrived at the shape recognized as being distinctly samurai. Leather and or iron scales were used to construct samurai armours, with leather and eventually silk lace used to connect the individual scales (kozane) which these cuirasses were now being made from.^[2]

In the 16th century Japan began trading with Europe during what would become known as the Nanban trade. Samurai acquired European armour including the cuirass and comb morion which they modified and combined with domestic armour as it provided better protection from the newly introduced matchlock muskets known as Tanegashima. The introduction of the tanegashima by the Portuguese in 1543^[3] changed the nature of warfare in Japan causing the Japanese armour makers to change the design of their armours from the centuries-old lamellar armours to plate armour constructed from iron and steel plates which was called tosei gusoku (new armours).^[4] Bullet resistant armours were developed called tameshi gusoku or (bullet tested)^[5] allowing samurai to continue wearing their armour despite the use of firearms.

The era of warfare called the Sengoku period ended around 1600, Japan was united and entered the peaceful Edo period, samurai continued to use both plate and lamellar armour as a symbol of their status but traditional armours were no longer necessary for battles. During the Edo period light weight, portable and secret hidden armours became popular as there was still a need for personal protection. Civil strife, duels, assassinations, peasant revolts required the use of armours such as the kusari katabira (chain armour jacket) and armoured sleeves as well as other types of armour which could be worn under ordinary clothing.^[6] Edo period samurai were in charge of internal security and would wear various types of kusari gusoku (chain armour) and shin and arm protection as well as forehead protectors (hachi-gane).^[7]

Armour continued to be worn and used in Japan until the end of the samurai era (Meiji period) in the 1860s, with the last use of samurai armour happening in 1877 during the Satsuma Rebellion.^[8]

Japanese armour was generally constructed from many small bamboo staves (tetsu) and/or leather (nerigawa) scales (kozane) and/or plates (ita-mono), connected to each other by rivets and macramé cords (odoshi) made from leather and/or braided silk, and/or chain armour (kusari). Noble families had silk cords made in specific patterns and colors of silk thread. Many of these cords were constructed of well over 100 strands of silk. Making these special silk cords could take many months of steady work, just to complete enough for one suit of armour. These armor bamboo plates were usually attached to a cloth or leather backing. Japanese armour was designed to be as lightweight as possible (thus the use of bamboo) as the samurai had many tasks including riding a horse and archery in addition to swordsmanship. The armour was usually brightly lacquered to protect against the harsh Japanese climate. Chain armour (kusari) was also used to construct individual armour pieces and full suits of kusari were even used.^[9]

Individual armour parts

A full suit of traditional Samurai armour could include the following items:

• Dou or dō, a chest armour made up of bamboo and or leather plates of various sizes and shapes with bamboo and hardend leather pendents.
• Kusazuri - the bamboo was cut into staves and steamed to work and shape them. This made the armor light compared with European armor and allowed samurai to perform their legendary fighting skills (which would have been impossible under the weight of iron or steel armour) made from bamboo staves (in a layer-upon-layer fashion, overlapping over the ribcage) and boiled leather plates or simply boiled hard leather overlapping hanging plates hanging from the front and back of the dou (dō) to protect the lower body and upper leg.
• Sode, large rectangular shoulder protection made from bamboo staves and or leather plates.
• Kote, armoured glove like sleeves which extended to the shoulder or han kote (kote gauntlets) which covered the forearms. Kote were made from cloth covered with lacquered bamboo plates of various size and shape, connected by chain armour (kusari).
• Kabuto, a helmet made from bamboo staves and leather plates (from 3 to over 100 plates) riveted together. A neck guard shikoro made from several layers of curved bamboo and boiled leather strips was suspended from the bottom edge of the kabuto.
• Mengu, various types of lacquered bamboo and or boiled hard leather facial armour designed in a way that the top heavy helmet kabuto could be tied and secured to them by various metal posts. Mengu had throat guards yodare-kake made from several rows of bamboo or leather plates or kusari (chain armour) sewn to a cloth backing, suspended from the bottom edge.
• Haidate, thigh guards which tied around the waist and covered the thighs. These were made from cloth with small bamboo and or leather plates of various size and shape, usually connected to each other by chain armour (kusari) and sewn to the cloth.
• Suneate, shin guards made from bamboo stave splints connected together by chain armour (kusari), sewn to cloth and tied around the calf.

Auxiliary armours

• Guruwa, a type of throat and neck protector.
• Nodowa, a type of throat and neck guard.
• Tate-eri, the tate-eri is a small padded pillow like piece with a standing armored collar that sits on the shoulder to protect from the weight of the dou (dō). The standing collar would be lined with kikko armor to protect the neck.
• Manju no wa, the manju no wa, (also manjunowa or manju nowa) is a combination of shoulder pads, collar and armpit guards in one that protected the upper chest area. Manju no wa were covered with kusari (chain armor), karuta (small armor plates), or kikko (brigandine), these armors or a combination of them were sewn to a cloth backing. The armor could be exposed or hidden between a layer of cloth. When worn the manju no wa looked like a small tight fitting vest. Manju no wa have small wings that would pass under the arm pit area from the back and attach to the front of the manju no wa.
• Manchira, the manchira is a type of armored vest covered with kusari (chain armor), karuta (small armor plates) or kikko (brigandine), these armors or a combination of them were sewn to a cloth backing. The armor could be exposed or hidden between a layer of cloth. Manchira are larger than manju no wa and protected the chest area and sometimes the neck and arm pit. Some manchira could be worn over the dou (dō).
• Wakibiki, the wakibiki is a simple rectangle of cloth covered with kusari (chain armor), karuta (small hard end leather and bamboo plates), or kikko (brigandine) these armors or a combination of them were sewn to the cloth backing. Wakibiki could also be made from one solid piece of iron or hardened leather. The wakibiki had cords connected to them which allowed the wakibiki to hang from the shoulder, the wakibiki was then suspended over the exposed arm pit area. Wakibiki were either worn inside or outside the chest armour dou (dō) depending on the type.
• Yoroi zukin, cloth hoods with various types of armour sewn to the cloth.
• Kogake, armored tabi, a kind of sabaton that covered the top of the foot.
