Antique Samurai Helmet Rokujuni Ken Koboshi Kabuto with Tokubetsu Kicho Shiryo Certificate

Period: Early Edo Period (appraised by The Association for the Research and Preservation of Japanese Helmets and Armor)

Prime Material: Iron

 This Kabuto’s style is the Koboshi Kabuto (小星兜), which is categorized as the Hoshi Kabuto (星兜), and it has Rokujuni (sixty two in Japanese) iron plates. The Hoshi Kabuto is a type of Samurai helmet that was born in the middle of the Heian period (around 888-1068). Small rivets that hold iron plates together. These rivets are called the Hoshi (星, star). In the Edo period, artisans made Kabutos not only Kawari Kabutos (please check the paragraph below) but also ancient-style Kabutos. For example, in the case of the Hoshi Kabuto, the Hoshis become smaller toward the top of the head; this form is called the Rinotori (厘劣り). It differs from the old-fashioned Hoshi Kabuto, in which all the Hoshis were the same size.

 The Kabuto is a protector of 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; Samurai warriors tried to express their dignity, personality, or religion by wearing the characteristic designed Kabutos. According to a theory, these uniquely designed Kabutos were made from the late Muromachi (室町, 1336-1573) to the Edo period (江戸, 1603-1868). 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 paper were used as materials for decorations.


 The Maedatemono (前立物, front decoration) is attached to this helmet. We think it is the combination of the Nichirin (日輪, another name for the sun). There was a widespread belief among Samurais; the Myouken (妙見) belief. This religion was born in India. It was mixed with the Polestar belief and was brought to Japan from the Continent. The sun, the moon, and the stars of the entire universe were the symbols of faith. The Myouken Bosatsu (妙見菩薩, 菩薩 means Bodhisattva) fulfills all wishes such as fertility of rich harvest, peace, the prosperity of the clan, healing of illness, longevity, success in business, traffic safety, academic achievement, marriage, etcetera. So, it is understandable that the sun motif was appreciated among Samurais. The former owner of this armor might have had shown his faith wearing this helmet.

 Uesugi Kenshin (上杉 謙信, 1530-1578), a famous feudal Daimyo (大名, a Japanese feudal lord), who ruled the Hokuriku (北陸) area also liked this design. He fought in lots of battles and won victory in most of them. Therefore, he was called the Gunshin (軍神, god of war). His helmet had the front decoration, and its motif was the combination of the Nichirin and the crescent moon. A theory says he believed the Myouken belief and especially worshipped the sun and the moon. By combining the Nichirin and a sword, this Metate’s designer might have tried to show his faith and determination to be successful on battlefields.

Also, the Fukikaeshi (吹き返し), both ends of a Kabuto, is attached to this Kabuto. It protects the face from swords and also shows its beautiful workmanship. Family crests are sometimes designed on this part, as seen on this Kabuto. This crest is called the Tachibana (橘). The Tachibana is a descendant of mandarin oranges. It has a strong aroma, and is resistant to snow damage, and grows well. Because of these characteristics, there is an anecdote that a person of good character and dignity was compared to being “like a Tachibana.” The custom of displaying peach blossoms and Tachibanas during the Momo-no Sekku (桃の節句, the Girl’s Festival, March 3rd) to this day. According to a theory, Tachibana came to be used as a motif of family crests because it was a prized plant. It is said that the ripened Tachibana fruits remain on the branches and emit their fragrance for an extended period, up to six months. In addition, evergreen trees have been regarded as lucky charms since ancient times, as they have the characteristic of not changing the color of leaves or falling and are associated with the idea “Tsunenaru Mono (常なるもの, eternal and unchanging).”

 

 This Kabuto is a set with this Menpo (面頬, face guard). This type of Menpo is called the Ressei Menpo (烈勢面頬). It represents the angry face to intimidate enemies. There are many types of Menpo, depending on their shape or appearance. The purpose of Menpo was not only to protect Samurai’s face. But also to hide their true faces so that their psychological states were unaffected. Beards are attached to this Menpo. Thanks to this effect, even a young soldier would have been able to produce the majestic appearance of a middle-aged Samurai.

 

*Please keep in mind that this Kabuto’s lacquer is partly lacked off.
