1: Historical Context Samurai armour changed over time: in the Heian Period (794-1185), armour was designed to be light and flexible because samurai fought on horseback, often as mounted archers; by the Azuchi-Momoyama Period (1573-1603), gunpowder weapons had been introduced via Dutch traders, causing samurai to wear a European-style plate cuirass for protection against musket balls. In the later Edo Period (1603-1867), Japan''s longest stretch of peace, armour was worn more as an expression of culture and status. 2: Construction Japanese armour contained leather, iron, steel, wool, cotton, and sometimes silk in its construction; despite popular perceptions, wood and bamboo were not used for Japanese armour. The building blocks of samurai armour were the kozane, lacquered iron and leather scales of various sizes. These scales were often attached to a mail backing called a kusari, which in turn was stitched onto a leather or cloth surface. 3: Types of Armour Arranged chronologically: * Tanko - The first iron armour appeared in the 4th century and was called tanko. This was for infantry combat and featured a distinctive lamellar construction. The cuirass (do) consisted of a metal frame and lamellae.
* Keiko - Without any doubt, the introduction of the keiko (or kake-yoroi), was connected with the importation of horses from continental Asia around the end of the 4th century or beginning of the 5th century. The Japanese quickly discovered that Korean armour, with scale construction, was much better than Japanese lamellar armour for fighting on horseback. * Kozane and Kebiki-odoshi - The basic type of scale was called o-arame. * O-yoroi - The o-yoroi (or ''great armour'') appeared in the beginning of the 10thcentury. It was specially designed for mounted archery and for several centuries was considered to be the only armour suitable for the high-ranking warriors(bushi). * Do-maru - At the beginning of this period retainers and servants usually wore simpler armour (do-maru), which appeared approximately in the same time with the o-yoroi or even earlier. * Haraate and Haramaki - Beginning in the 15th century, the constantly-increasing light infantry (ashigaru) was equipped with a new type of armour called haraate (''protection of the abdomen''). * Kusari - Japanese mail, appeared in the 14th century.
It differed from European mail in both construction and use. * Mogami-do gusoku - The earlier variants of the mogami-do gusoku, which appeared in the late 15th/early 16th centuries were considered to be transitional types of armour. * Maru-do gusoku - The maru-do was a modern variant of the do-maru and usually was the armour of high-ranking warriors. It was opened under the right arm like classical armour but was of lamellar construction. * Ni-mai-do gusoku - Strictly speaking, the ni-mai-do was not a particular type of armour but was a term for a group of armours of different construction. The name means ''cuirass of two sections'' and directly refers to their common feature. * Okegawa-do gusoku - Around 1550 a new type of armour appeared, and soon became extremely widespread due to all its advantages. This was the okegawa-do or the armour of riveted lamellae.
The name means ''tube-sided'', because the cuirass had a tube-like shape and construction. * Tosei-gusoku - in the beginning of the 16th century the Classical armours were replaced by tosei-gusoku (''Modern armours'') of lamellar construction. These exhibited enormous variety but their common feature was minimal use or total absence of lacing (as in the riveted and full-plate cuirasses). The Modern armours offered better protection against firearms, introduced to Japan in 1543 and first used in battle in 1549. * Namban-do gusoku - The namban-do gusoku or ''armour of the south barbarians'' was one of the results of contact with Europeans. Japanese armourers quickly learned how to produce local copies of European plate armour, and starting around 1560 the namban-do ''Made in Japan'' appeared. Although the quality varied widely, these always were associated with the high-ranking samurai.

The motifs could be abstract patterns, simple shapes, or representations of nature like flowers, or they could be kanji representing a motto. For example, the mon of the Hojo family is an arrangement of three triangles forming a larger triangle. Some mon survive as company logos today: the Mitsubishi logo is the most recognizable.
