Description
Kusari is the Japanese word for "chain". It is used to describe mail armor as well.
The full description would be: Kusari gusoku (鎖具足), literally: "chain armor". The jackets are called kusari katabira (鎖帷子), and the hoods kusari zukin (鎖頭巾).
The rings are usually much smaller than that on the mail of other cultures and are almost invariably stiched to a fabric or leather undergarment, or sandwiched between two layers of fabric. According to George Cameron Stone, Japan had more variety of mail than all the other cultures combined and many combinations of patterns exist, some with plates in-between.1
It was worn by samurai and soldiers of feudal Japan, up to the late 1860s.2
