Antique Edo Period Nimai Do Samurai Armor with Tokubetsu Kicho Shiryo Certificate (A-45)
Period: Mid Edo Period
Kabuto (helmet)
■Helmet bowl: Suji Kabuto
The Kabuto (兜, helmet) is a protector for the head. When people started using the Kabuto, it was initially designed for practical use. However, the principal purpose of its design has changed with time; Samurais tried to express their dignity, personality, or religion by wearing the characteristic designed Kabutos. According to a theory, these unique designed Kabutos were made from the late Muromachi period to the Edo period. This type of Kabuto is categorized as the Kawari Kabuto (変わり兜), and a variety of materials were used to create them. For example, animal fur, seashells, plants, and papers were used as materials for decoration.
Here we would like to introduce to you a little bit more about the history of Kabutos. Before the Kawari Kabuto’s production, the Suji Kabuto (筋兜) has appeared during the Nanbokuchou (南北朝, 1337-1392) period. At that time, the tactic was gradually changed from the piggyback fight style to battle with the Tachi (太刀) sword and the Naginata (薙刀, Japanese halberd) on the ground. Therefore, there was a rise in demand for the weight saving of the Kabuto. Also, in order to turn the attack by swords, a new type of structure was invented; it is the Suji Kabuto (筋兜). Its form slides swords’ attacks when weapons hit the Kabuto. It is said that the production of the Suji Kabuto prospered in the Muromachi (室町, 1336-1573) period.
■Shikoro (side neck guard):
Black lacquered plates laced with navy blue threads.
■Fukikaeshi (side neck guard)
The Fukikaeshi (吹き返し) is both ends of a helmet. It protects the face from swords and also shows its beautiful workmanship.
The Fukikaeshi of this Kabuto features a kamon (family crest) known as Kokumochi-jinuki-mokko (石持ち地抜き木瓜). This is a variation of the Mokko-mon (木瓜紋), one of Japan’s traditional family crests. The Mokko-mon is said to be inspired by a bird’s nest and is often used as a symbol of prosperity and lineage.
“Kokumochi-jinuki” refers to a design where a circular element (ishimotsu) is placed at the center, with that section left in the background color (ji-nuki). This adds an accent to the otherwise simple Mokko-mon.
The Mokko-mon has been widely used by many samurai clans and shrines. In particular, it is known to have been the family crest of the Kuki and Inaba clans
■Menpo (face guard):Hanpo
This type of Menpo is called the Hanpo (半頬).
■Kuwagata (Front decoration):
The Maedatemono (前立物, front decoration) is attached to this helmet. We assume that the Maedatemono of this Kabuto is a type of Kuwagata (鍬形).
Armor
■Do (cuirass): Okegawa Nimai Do
The Nimai Do (二枚胴) is a kind of cuirass for Tousei Gusoku (当世具足, developed armor style). Since Nimai (二枚) means two plates, and Do (胴) means torso in Japanese, this type of Do is called this name. This Do uses many small lamellar plates called Kozane (小札, small strip-shaped plate).
The name Okegawa (桶側) came from the fact that the shape of this cuirass resembles the side (Gawa in Japanese) of Oke (Japanese wooden tub). The body armor part can be separated into two pieces and connected with a hinge. Typically, the hinge is located on the left side, and you can tighten this cuirass on the right side. This Do is made of black lacquered iron plates, and these were laced with navy blue thread.
■Kusazuri (skirt of plates attached to the cuirass):
Lacquered iron Kusazuri laced with navy blue threads.
*Please keep in mind that some of the thread aren’t connected to plates due to the aging of the silk. If you don’t mind waiting, we will be happy to have these part refurbished. For details, please feel free to contact us.
Small parts
■Kote (armored sleeves):
Intricate iron chain mail with silk.
■Haidate (thigh protection):
The Haidate (佩楯) is a thigh guard. Chain mail and iron plates are attached to its cloth.
■Suneate (shin guard):
The Kikkou (亀甲, turtle’s shell) pattern is used for the cloth of the Suneate (脛当). It is a continuous geometric pattern connecting regular hexagons up and down. A theory says that this design was brought from China and the Korean Peninsula during the Asuka (飛鳥, 592-710) and Nara (奈良, 710-794) periods. A proverb says turtles live long lives; therefore, turtle and turtle shell patterns represent longevity. In addition, as this continuous hexagonal pattern does not get out of its shape, it is said people wished for eternal prosperity by using this design. This Suneate is a type called Kusari sunete (chain armor shin guard). It features chains attached to fabric, with minimal gaps between the metal links.

A family crest called Sujikai (直違) is decorated on this box.
