Dō (breastplate or cuirass) is one of the major components of Japanese armour worn by the samurai class and foot soldiers (ashigaru) of feudal Japan.

History

Ancient Japanese iron helmet and armour (tanko) from the Kofun period, 5th century. The tanko is the predecessor of the dō, Tokyo National Museum.

The predecessor of the samurai cuirass, or dō, was 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 by leather thongs.

During the Heian period (794 to 1185) the Japanese cuirass evolved into the more familiar style of armour worn by the samurai known as the dō. Japanese armour makers started to use hardened leather along with iron in their armour construction 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 cuirasses 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] along with a change in battle tactics caused the Japanese armour makers to change the design of the dō from the centuries-old lamellar armours to plate armour constructed from iron and steel plates, this type of armour was called tosei gusoku (new armours).[4] Bullet resistant dō were developed, this type of armour was called tameshi gusoku (bullet tested)[5] allowing samurai to continue wearing their armour despite the increasing use of firearms.

The warfare of the Sengoku period (15th and 16th centuries) required large quantities of armour to be produced for the ever growing armies of foot soldiers (ashigaru). Simple munition quality (okashi or lent)[6]dō were massed produced including tatami dō which could be folded.[7]

The victory of Ieyasu Tokugawa at the Battle of Sekigahara in 1600, and his subsequent rise as Shogun in 1603, marked the end of the Sengoku period. By this time samurai continued to use both plate and lamellar cuirasses as a symbol of their status, but traditional armours were no longer necessary. During the Edo period, lightweight and concealed armour became popular as there was still a need for personal protection. Civil strife, duels, assassinations, peasant revolts required the use of tatami dō as well as kusari katabira (chain armour jackets) and armoured sleeves as well as other types of armour which could be worn under ordinary clothing.[8] 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).[9]

Traditional armor 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.[10]

Types of dō

The type of dō that originally came with a matched suit of armour defined the name for that particular suit of armour, for example, a suit of armour that came with a hotoke dō would be called a hotoke dō gusoku; a suit of armour that came with a karuta tatami dō would be called a karuta tatami dō gusoku.

Kozane dō

True kozane dō are of lamellar construction using individual scales known as kozane, they were used before the introduction of firearms in Japanese warfare.[11][12]

  • O-yoroi, an early type of dō used by mounted samurai and constructed with hon kozane.
  • Dō-maru, an early type of dō with no hinge that opened on the right side, constructed with hon kozane.
  • Haramaki dō) originally an early type of dō which opened in the back, constructed with hon kozane, in later times "harimaki" was used to describe any dō that opened in the back.
  • Hon kozane dou (dō), any dō constructed with hon kozane.
  • Hon-iyozane dou (dō) or Nuinobe dō, any dō constructed with hon iyozane.

Types of kozane

Kiritsuke kozane dou (dō)

False kozane dou (dō) in the form of kiritsuke hon iyozane or kiritsuke hon kozane mimic the construction of lamellar armour but instead of being made from true individual scales kiritsuke kozane are actually constructed with long lames (strips or rows) of armour lashed together and are a form of laminar armour.

Tosei dou (dō)

Tosei dou (dō) (tosei meaning modern), were made from iron plates (ita-mono)[13] instead of individual scales (kozane). Tosei-gusoku became prominent starting in the 1500s due to the advent of fire arms, new fighting tactics and the need for additional protection.[14][15]

  • Okegawa Dou (dō) guskou - (tub-sided), refers to the tub-like shape of the dou (dō). There are two types of okegawa dou (dō): yokohagi (horizontal lames), and tatehagi (vertical lames).
  • Hishinui dou (dō) or Hishi-toji dou (dō) - chest armours with rows of prominent cross knots, usually an okegawa dou (dō).
  • Munemenui dou (dō) or Unamenui dou (dō) - chest armours with a running stitch that goes horizontally across the surface of the dou (dō). This stitch of lacing runs along the surface of the lame looking like a dotted line paralleling the top.
  • Dangae dou (dō) gusoku - meaning "step-changing", a combination of two or more styles.
  • Hotoke dou (dō) gusoku - chest armor which is smooth and shows no signs of lames.
  • Nio dou (dō) - embossed to resemble the emaciated torso of a starving monk or old man; named in resemblance of the Buddhist deities of the same name.
  • Katahada-nugi dou (dō) - embossed to resemble a half-naked torso.
  • Yukinoshita or Sendai dou (dō) - A five plate, four hinge (go-mai) chest armor in the sendai or yukinoshita style.
  • Hatomune dou (dō) gusoku - (pigeon-breast chest armour or cuirass) were inspired by European peascod breastplate armour. Hatomune dou (dō) have a sharp central ridge running vertically down the front.
  • Uchidashi dou (dō) gusoku - Embossed or hammered out relief on the front.
  • Nanban dou (dō) gusoku — Armour made on the base of late European armour
  • Mōgami dou (dō) - five-plate, four hinge (go mai) chest armours with solid lames which are laced with sugake odoshi instead of being riveted.

Tatami dō

Tatami dō (folding or foldable) were made from small square or rectangular armour plates (karuta) or hexagon armour plates (kikko) that were usually connected to each other by chain armour (kusari) and sewn to a cloth backing, tatami dō could also be made entirely from kusari.[16] Tatami dou (dō) were lightweight, portable, convenient for transportation, and were manufactured inexpensively and in great numbers for the ashigaru light infantry.[17]Tatami dou (dō) were worn by all samurai classes from the highest class to the lowest class. The higher class samurai wore elaborate tatami dou (dō)[18] while the lower class samurai and retainers wore plainer, simpler designs
