The Zunari Kabuto, also known as the Three-Plate Kabuto or Head-Shaped Kabuto, is a helmet worn by Japanese samurai as part of their armor (Yoroi).
The Zunari Kabuto is made of iron and belongs to the category of Three-Plate Kabutos, as the helmet bowl is composed of three solid plates. There are two main versions known as Hineno Kabuto and Etchu Kabuto. The difference between these helmet versions lies in the way the central large plate interacts with the plate protecting the eyes: in the Hineno Kabuto, the central plate runs beneath the eye protection plate, while in the Etchu Kabuto, the central plate overlaps the eye protection plate.
The additional ornamentation of the helmets can vary greatly. Generally, the helmets are equipped with side guards (Fukigaeshi), a neck guard (Shikoro), a helmet crest (Maedate), and a securing cord (Shinobi-O-Noh) to fasten the helmet to the head. Face masks (Menpo) were often worn together with this type of helmet. In Japan, the helmets were frequently lacquered in different colors. This served both as decoration and to protect the metal of the helmet from the effects of weathering.
