O-Yoroi

Worn almost exclusively by high-ranking samurai, o-yoroi—or "great armor"—is a heavy combat armor that consists of various supplementary components that include both plate and lamellar elements. Each suit is crafted for a specific individual and displays the owner's aesthetic. Upon completion, the suit is colored and sealed with a final lacquer finish. The centerpiece of o-yoroi is a cuirass consisting of two parts—a separate reinforcement for the right side called a waidate, and a kikko cuirass. The upper part of the waidate consists of a leather-covered iron plate. The cuirass's leather shoulder straps—called watagami—are likewise armored with metal plates. Affixed to the cuirass are a number of supplementary pieces, including wide lamellar shoulder guards, a kikko sleeve for the shield arm, lacquered iron greaves worn over padded silk leggings, and a groin protector. The signature component of each suit of armor is the tiered kabuto helmet and its accompanying ho-ate mask. Ho-ate masks can be made of hardened leather or metal and are fashioned into fearsome visages such as oni, dragons, or other mythical beings.
