Japanese Arms and Armour
The Samurai - ‘those who serve’History of the Samurai - ‘those who serve’
From the 9th century AD, landowners with links to the Japanese Emperor rose to promnence and attracted armed supporters or ‘retainers’ who became the buke (the upper classes). From this social elite were drawn the samurai, a noble caste that included women, children and non-combatant men as well as warrior males.
Over the next two centuries, two clans – Taira and Minamoto – clamoured for power, a struggle that culminated in the Genpei Wars. Taira and Minamoto samurai warriors wore red and white, the families’ respective colours, and carried fans displaying a rising-sun symbol. These became Japan’s national colours and emblem. They can be seen today on the country’s flag, which represents a red sun disc on a white background. Victory for Minamoto no Yoritomo in 1185 led to him becoming the first shogun with nationwide authority. The feudal shogunate system supported the samurai as a martial aristocracy and the vehicle through which military power was exercised. The Emperor’s role was retained but he was reduced to a mere symbolic figure for nearly 700 years.
Samurai favoured rigorous Zen Buddhism and followed bushido (‘the way of the warrior’). This training included archery, horsemanship and swordsmanship. It also taught adherence to a strict moral code emphasising frugality, self-control, cour- age and loyalty until death. This often resulted in a samurai committing seppuku (ritual suicide by disembowelment) upon the death of his lord. During the medieval period many of the greatest samurai heroes appear. Minamoto no Yoshitsune (1159–89) and Kusunoki Masashige (1294–1336) both died heroes’ deaths and are still regarded in Japan as epitomes of the samurai ideal.

Later, in 1702, another event further enmeshed the samurai code into Japanese life. A group of 47 samurai sought revenge for the suspicious death of their lord by killing the perpetrator and placing his head on their lord’s grave. As a final act of conscience and loyalty, these ronin (‘masterless’ warriors) all committed seppuku and were buried at the Sengaku-ji monastery in Tokyo.
The story of the ‘47 Ronin’, entered over time into folklore, a mythical metaphor for the moral qualities to which all good Japanese people should still aspire. This theme of self-discipline, sacrifice and devotion was embodied by the kamikaze pilots of the Second World War.
However, the samurai ideal was not always upheld. During the Sengoku (‘Warring States’) Period (1478–1615), Japan experienced ongoing civil strife. A samurai’s giri (obligation) to his lord was often forgotten when treachery and opportunism became necessary to survive. Three great 16th century daimyo (feudal lords) – Oda Nobunaga, Toyotomi Hideyoshi and Tokugawa leuyasu – successively ended this chaos to create a united Japan. As grand minister in 1588, Hideyoshi codified the samurai caste as permanent and heritable and forbade non-samurai to carry weapons. These laws sought to prevent peasant uprisings and effectively end the social mobility that had hitherto characterized Japan and which had, ironically, enabled Hideyoshi’s rise to power from his lowly origins.
By 1615, Tokugawa had suppressed the daimyo, eliminating potential threats to his power and ushering in the peaceful Edo period (1603–1868). Many retainers of dispossessed daimyo had to swap their warriors roles for posts as diplomats or administrators, whilst around 500,000 samurai became wandering, redundant ronin. By the 18th century, bushido had almost disappeared, but a few strove to keep the code alive. Miyamoto Musashi, probably Japan’s greatest samurai swordsman, developed a school to teach his unique techniques. His Book of Five Rings (1645), a treatise on sword strategy and philosophy, is still studied today.
During the 19th century, dissatisfaction with the old shogunate order resulted in civil war. Upon the restoration of Imperial rule in 1867–8, the special status of the now-archaic samurai was retracted. However, the rapid modernization of the Meiji period (1898–1912) rekindled an enduring nostalgia for the samurai as a symbol of Japan’s glorious past and traditional culture.
The distinctive appearance of Japanese armour derives from the padded styles imported from China and Korea during the first millennium AD. By the late Heian period (10th century), the box-like o-yoroi (‘great armour’) appeared. It comprised a dõ, a body armour that wrapped in a ‘c’ shape around the body, and a haidate, an armoured thigh-guard apron. These were made of varying-sized strips of lamellae (small plates or scales arranged in overlapping horizontal rows) or iron plates, held together by silk lacing. Protecting the head was a large, multi-plate kabuto (helmet) fitted with a wide shikoro (neck guard) and large fukigaeshi (turn- backs). These hallmarks of Japanese armour design were to remain largely unchanged for centuries, bar certain refinements and cosmetic alterations.
Stenciled leather inner
-boots; 1901.46.1.16-.17The early samurai were, first and foremost, mounted warriors, the bow taking precedence over the sword. To prevent o-yoroi being too heavy to wear on horseback, leather was used to cover less vital areas of the body. Accompanying the armour were fabric undergarments and animal skin boots, mounted with brass splints to prevent cuts to the feet. The bushi warriors observed a rigid hierarchy in footwear materials, only generals or daimyo being permitted to wear the highly prized bearskin. Soft leather, mitten-like boots were worn underneath.
In 1543, the Portuguese introduced firearms to Japan. This resulted in a demand for simpler, sturdier armours that could be produced en masse to feed the

These new armours reflected considerable European influence in their use of chain mail, a hinged plate cuirass (breastplate and backplate) and a three- plate, morion-style helmet known as a hineno zunari kabuto or ‘head-shaped helmet’. Kabuto often fea- tured crests such as a crescent moon, the Buddhist symbol of the impermanence of life.
As an added protection, kabuto were also worn with a mempo (face mask). These could be embellished with moustaches, teeth and fearsome expressions. However, they could also cause fatal misidentification on the battlefield prompting the use of other identifiers such as sashimono (banners). The zunari helmet and mempo are said to have inspired Darth Vader’s helmet in the Star Wars films.
Display armour, Edo period;
During the peaceful years of the Edo period (1603–1868) armour became more decorative than functional. On alternate years the daimyo were obliged to travel to Edo (modern Tokyo) seat of the shogun. They took large samuraientourages with them on these long processions, which were dressed and equipped in a way that declared their lord’s
Tosei-gusoku armour, c.1700;
1941.4.58power and prestige. Armour was a tableau for displaying messages. Many were adorned with sacred or cultural symbols and kamon (circular heraldic badges). Some very ornate armours were presented as diplomatic gifts.
In the early 18th century, the master armourer, Arai Hakuseki, expressed his dissatisfaction with these showy, impractical armours and a nostalgia for the grand o-yoroi armours of the past. His treatise, The Armour Book in Honcho-Gunkiko, heralded a shift back to the past in armouring styles. Whilst it is generally possible to date European armours to within a 10–20 year range, it is more difficult to pin down exact manufacture dates for Japanese armour. This is due to more subtle stylistic changes, the mix of old and new and the extremely high quality of the tosei-gusoku (modern armours) that revived archaic forms.
This suit was made in the 18th century by the Unkai school but superbly imitates the style in fashion during the late Muromachi period (late 16th century). For example, the pared-down zunari kabuto (helmet) discussed above has been replaced by an 18-plate suji-hachi kabuto reminiscent of that era.
Japanese armour possesses a unique beauty and it is thus not surprising that suits and accessories became especially collectable after 1868 and the decline of the samurai. Many examples now reside in museums and private collections around the world.
Mounted archery was the primary and most respected mode of Japanese warfare until the introduction of firearms in the 16th century. As a reflection of this, archery equipment was beautifully crafted, the quivers and specialized deerskin gloves often bearing decoration and kamon. Quivers were typically made of basketwork, paper and leather and contained arrows of bamboo and bird feathers. Unusually, the quiver was sealed at the top. Arrows were stored nock downward and pulled out through a flap at the base. This may have been to aid quick retrieval in battle or to prevent rainwater getting into the quiver.

Yokohama, 1873'; 1992.16.3The yumi was the longest bow used anywhere in the world, measuring 2.2–2.7m long. Although ostensibly similar to the English longbow, its limbs were in fact asymmetrical, the grip being positioned one third of the way up to enable use on foot or horseback. Such bows were ‘composite’ and usually comprised three layers – a rigid wooden core sandwiched
between flexible bamboo on the back and belly. These layers were then glued, bound with cane strips and lacquered. The art of kyudo (‘Way of the bow’) is the oldest of Japan’s martial arts, while shajutsu (military archery) was a vital skill of the samurai. Training included kasagake (aiming for a hat on a pole) and inouomono (shooting at dogs in a fenced-in paddock) whilst galloping on horseback. The master archer, Heki Danjo (died 1502) maintained a philosophical approach, stating that a great Japanese archer must possess the correct focused mental attitude as well as skill.
During the Kamakura period (1185–1336) samurai also practised archery for purposes of sport or ceremony. For example, toshiya hiyakazu, the ability to stand and shoot arrows continuously along a roofed gallery from dawn until dusk, was considered a great entertainment skill and also provided a great public spectacle.
Bows continue to play a significant role in Japanese culture. They are used to celebrate New Year and a baby’s birth while the sound of a bowstring being plucked is said to ward off evil spirits.

Utsunomiya battlefield, Tokyo, 1868, when the
Imperial army routed the shogun's men; 1936.12.3Japanese staff weapons were used by samurai and ordinary foot soldiers. Spears or yari date from early times and were generally not for throwing. Their blades ranged from 15cm to 64cm (6–25 inches) in length whilst the poles ranged from 1.8m to 2.4m (6–8 feet) and were sometimes lacquered and inlaid with shell. The most common weapon of this type was a pole affixed with a sword-like blade known as a naginata, traditionally used by samurai women defending a fortification while their men were away.
Japanese Swords or Nihon-To
Tachi blade and shira saya (wooden storage sheath). Mino
school, c. 1350. The tachi is only Japanese sword to be worn
and displayed blade down; 1938.35.1436Japanese blades assumed their trademark curve by the 10th–13th centuries when it was discovered that a curved sword could be drawn more quickly and provided a more effective cutting angle. However, their single-piece steel construction lacked durability, a weakness exploited by the tough leather armour of the Mongols in the invasions of 1274 and 1281 when only violent typhoons saved the Japanese.
Single-edged kozuka (scabbard knife) with bronze handle, embossed with
gilded dragon, mountain and clouds; 1934.25.56The legendary sword-smith Masamune Okazaki overcame this problem by developing the classic two-piece blade, formed by ‘sandwiching’ shingane (a soft low-carbon core) within kawagane (a hard jacket steel). Generally, only tanto (a ‘dirk’ or long dagger) remained single-piece constructions from this point on.
There arose five main sword traditions, each with their own smithing method – Yamoto, Yamashiro, Bizen, Soshu (founded by Masamune) and Mino – from which hundreds of smaller schools derived. More than 30,000 smiths appear in recorded Japanese history, with around 300 active today. Many of these modern smiths take part in a competition in Masamune’s name to create an exceptional sword.
Making a Japanese sword is a complex process. It takes a smith two weeks to forge a blade since the jacket steel may be folded up to twenty times. Forming the kissaki (point) requires the utmost skill, explaining why a sword’s value is largely determined by the quality of the kissaki. To achieve its famed hardness, the blade is heated to 800°C, then plunged into cold water, a process that actually alters the atomic crystalline structure of the metal. Polishing takes another two weeks, using polishing stones of ten or more different grades of roughness. This fully exposes the beautiful products of the forging process, such as the jihanda (wood-grain effect) or the hamon (the ‘temperline’ on the cutting edge).
Japanese swords are usually displayed horizontally, the blade facing upward, so that the hamon can be seen and appreciated. Specialist craftsmen make the furniture worn by the blade. This comprises the koshirae (soft mounts) and the kodogu (metal mounts). The saya (decorative sheath) often has small pockets for kozuka (knives) and kogai (skewers).

historical periods. The inscription

era', i.e. August, 1637. (image

One of these involved cutting through the bones of the corpses of criminals. The results could be inscribed on to the nakago (known in English as the ‘tang’; the extended part of the blade that forms the handle). Other inscriptions on the nakago could include the signature of the smith, his place of work and thedate of manufacture.
By the 1390s, Japanese swords had become lighter with long, slender blades and Samurai were seen in civilian dress wearing the katana. This long sword was said to represent the soul of the samurai and only they were permitted to wear it. It was usually worn as a daisho, that is, paired with the wakizashi, a shorter sword. The daisho came with a variety of decorative mounts to suit the occasion. Samurai also wore paired swords in combat, usually favouring the tanto (dagger) and the tachi, the original Japanese long sword worn blade down, traditionally for use on horseback.
The katana eventually succeeded the tachi during the civil wars of the Sengoku period (late 15th–16th centuries) as it was slightly shorter in length (averaging 70 cm) and worn blade up in the girdle, making it easier to draw in close combat and wield on foot. The tanto, on the other hand, survived longer in common usage. These rather plain and functional weapons were intended for stabbing and committing seppuku, the ritualised suicide demanded by bushido to prevent enemy capture and the shame that accompanied defeat. The tanto were still carried, and seppuku still practised by officers during the Second World War, many of whom were descendants of old samurai families.
Daisho (pair of swords)made by Echizen Kanenori c.1670; 1929.17.3There are several parallels between the historical trends in sword making and armour manufacture. The mass-produced armour of the 16th century civil wars was paired with lower quality, rapidly-produced swords, known as kazuuchi. The records of this time show one smith producing thirteen in a single week. The social upheavals also led to some merchant and lower classes wearing short swords, a trend deemed dangerous by Toyotomi Hideyoshi in 1588. His famous ‘sword hunt’ policy forbade peasants from owning weapons, returning that exclusive right to the bushi (warrior) classes.
Tanto (dagger); 19126.96.36.199 The peaceful Edo period (1603–1868) favoured well-made, highly decorated swords to accompany ostentatious armours. This heralded the Shinto (‘new’) era of sword making. Just as the 18th century beckoned a return to the antique styles of armouring, it also witnessed a revival of sword-making in the classical Koto (pre-1596) tradition. This became known as the Shinshinto (‘new new’) sword erawhich, fuelled by the bubbling nationalism and militarism of the 19th century, resulted in the production of many fine, robust and practical blades.
After 1868–77, sword making as a craft virtually ceased to exist, as the samurai were abolished and the carrying of swords banned. Many were sold to, or collected by, Europeans and Americans.

The huge demand for swords during Japan’s expansion into Asia and the Pacific in the early Showa period (1926–1945) meant munitions-standard arms had to be supplemented by gendai blades, that were modern in concept yet hand-crafted in the traditional way.
