History

Japanese helmets dating from the fifth century have been found in excavated tombs. Called (visor-attached helmet), the style of these kabuto came from China and Korea and they had a pronounced central ridge.

, which is now known as a samurai helmet, first appeared in the 10th century Heian period with the appearance of ''ō-yoroi''. Until the early Muromachi period, were made by combining dozens of thin iron plates. Generally, only daimyo and samurai at the rank of commander wore ornaments called , which were shaped like a pair of hoes. In the middle of the Muromachi period, as the number of large-scale group battles increased, ordinary samurai wore in the shape of hoe, sun, moon or flag on their to show their courage or to distinguish friend from foe.変わり兜展.

In the Sengoku period in the 16th century, when the war became extremely large-scale and the guns called became popular, the armor styles called and became outdated and the armor style called was born. are made by combining three to four pieces of iron plates, and they are more bulletproof than the conventional style, enabling mass production, and the became more eccentric and huge. Some of these were made of iron, but for safety reasons on the battlefield, they were sometimes made by putting paper on a wooden mold, coating it with lacquer and curing it, and extracting the mold. In the Azuchi–Momoyama period, had a simple yet more unique and bold design in accordance with the popularity of Momoyama culture.

In the Edo period, when the Tokugawa shogunate defeated the Toyotomi clan at Summer Siege of Osaka and the society became peaceful, armor with a revival of the medieval times became popular, and and style were made again.甲冑に見る江戸時代展5 武士と武人の甲冑像

The kabuto was an important part of the equipment of the samurai, and played a symbolic role as well, which may explain the Japanese expressions, sayings and codes related to them. One example is (lit. "Tighten the string of the kabuto after winning the war"). This means don't lower your efforts after succeeding (compare to "not to rest on one's laurels"). Also, (lit. "to take off the kabuto") means to surrender.

Parts of the ''kabuto''

The basic parts of the kabuto include:
*, a dome composed of overlapping elongated plates called
*, a small opening at the top of the , usually fitted with a (an ornamental grommet, often resembling a chrysanthemum)
*, a brim or visor on the front of the
*, a cloth lining inside the
*, mounting points for attaching crests
*, a ring at the back of the for securing a (helmet flag)
*, wing-like or ear-like projections to the sides of the
*, a suspended neck guard composed of multiple overlapping lames
* (chin cord), often used to secure the (facial armour)

A typical features a central dome constructed of anywhere from three to over a hundred metal plates riveted together. These were usually arranged vertically, radiating from a small opening in the top. The rivets securing these metal plates to each other could be raised (a form known as ) or hammered flat (a form known as ); another form, called , had the rivets filed flush. Some of the finer were signed by their makers, usually from one of several known families, such as the Myochin, Saotome, Haruta, Unkai, or Nagasone families.

A small opening in the top of the , called the or (seat of the war god, Hachiman), was thought to be for passing the warrior's top knot through. Although this practice was largely abandoned after the Muromachi period, this opening may have been retained for purposes of ventilation or simply as an artifact of how the plates were riveted together. The was usually decorated with , which were rings of intricately worked, soft metal bands often resembling a chrysanthemum. and were two helmet forms that did not usually have an opening at the top.

incorporated a suspended neck guard called a , usually composed of three to seven semicircular, lacquered metal or oxhide lames, attached and articulated by silk or leather lacing, although some were composed of 100 or more small metal scales in a row. This lamellar armour style, along with (mail armour), was the standard technology of Japanese body armour, and some were made of mail sewn to a cloth lining (a form called ).

The was secured to the head by a chin cord called , which would usually be tied to posts or hooks on the (facial armour) or simply tied under the chin.

''Kawari kabuto'', or strange helmet

During the Momoyama period of intense civil warfare, kabuto were made to a simpler design of three or four plates, lacking many of the ornamental features of earlier helmets. To offset the plain, utilitarian form of the new helmet, and to provide visibility and presence on the battlefield, armorers began to build fantastic shapes on top of the simple helmets in (papier-mâché mixed with lacquer over a wooden armature), though some were constructed entirely of iron. These shapes mimicked forms from Japanese culture and mythology, including fish, cow horns, the head of the god of longevity, bolts of silk, head scarves, Ichi-no-Tani canyon, and axe heads, among many others. Some forms were realistically rendered, while others took on a very futuristic, modernist feel.
