| - 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 dou or dō. Japanese armour makers started to use hardened leather (nerigawa) along with iron in their armour construction and lacquer (urushi) 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. 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 along with a change in battle tactics caused the Japanese armour makers to change the design of the dou (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). Bullet resistant dou (dō) were developed, this type of armour was called tameshi gusoku (bullet tested) allowing samurai to continue wearing their armour despite the 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)dou or dō were massed produced including tatami dou (dō) which could be folded. 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 dou (dō) 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 tatami dou (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. 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). Dou (dō) and other 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.
