General description
The Nara period (710-794CE) begins with the creation of a specially built imperial capital, laid out in a 20sq km grid, modelled on T’ang Chinese capital, Ch’ang-an.
[1]
Japan’s geography, provided some insulation from unwanted incursions from the continent, and allowed the court to exert some control over external political relationships.
[2]
However, during this period Japan was engaged in a vassalage relationship with T’ang China which influenced many aspects of Japanese culture, from city planning to the ‘ideal of imperial rule’.
[3]
The state used its military prowess to exert control over much of the territory of the archipelago, although the northern and southern extremes remained beyond centralized control.
[4]
The Peak Date can be considered to run from 781-794CE which has been idealized as ‘when Japanese rulers most closely approached the ideal reigns of the sage-kings of ancient China.’
[5]
Nara period ends with permanent relocation of the capital to Kyoto.
Population and political organization
Imperial rule was direct and legitimised by divine descent.
[6]
[7]
The government continued to strengthen and centralize its rule with administration and legal reforms inspired by the Chinese ritsuryo system.
[1]
The complex administration was arranged in offices which came into existence at different times, and were solidified in the code of 701 and the Yoro code of 718
[8]
Population for this period, as estimated by Farris, ranges from roughly 5 to 7 million.

’in 710, the capital was moved to Heijo, better known now as Nara. Nara was modelled on the T’ang Chinese capital, Ch’ang-an. It was a similar rectangular grid pattern, but at 20 sq km was only about a quarter of Ch’ang-an’s area. In less than a hundred years the capital was to move again. Nara proved not to be the hoped-for permanent site. Nevertheless, it represents the high point of the Japanese effort to learn from China. Physically, China’s influence was seen not only in the design of the city but also in grand buildings such as the Todaiji Temple - the largest wooden building in the world - and the huge bronze statue of Buddha it contained.

’In fact, historians, both medieval and modern, of loyalist sympathies regard as the golden age of Japanese history those decades of direct rule by enlightened, "virtuous" emperors - Kammu (781-806) and Saga (809-23), and again Uda and Daigo (887-930). For loyalists, these were the years when Japanese rulers most closely approached the ideal reigns of the sage-kings of ancient China.’ [1]

These were years of vast and fundamental change in the island kingdom, of cultural forced feeding and vigorous new growth.

Participation meant religious and philosophical orientations, an ideal of imperial rule, legal and administrative structures, techniques and styles of architecture, city planning, sculpture, painting, and music - all derived directly or indirectly from China and shared in one degree or another by the peoples on its periphery.’ [2]

’The government was run by a system of offices ranging from those closest to the emperor to others at more distant places and at lower levels. These offices had histories of their own, coming into existence at different times with different names and functions. Here we shall survey merely the ones that were probably named and defined in the Taiho administrative code of 701 and the Yoro code of 718.
[1]
’Down through the administrative structure - from the heads of offices around the emperor to those in charge of local offices in distant regions - ran a hierarchy of office titles and ranks. Heads of the highest offices held the title of director (kami) who had assistants (suke), secretaries (jo), and clerks (sakan). (These four office titles were written with different characters but pronounced in the same way when held by officials serving in different ministries and agencies.) According to the Yoro adminstrative code of 718, the number of officials in the two councils and eight ministries totaled 331. If lower-ranking officials are added, the total was 6,487. Ranks provided a more precise indication of status than titles did, for officeholders with the same title had different ranks yielding different stipends and perquisites. The Taiho code set aside four imperial ranks (hon) for princes and near relatives of the emperor and thirty court ranks (kurai) for persons lower in the aristocratic order. The son or grandson of a nobleman holding the highest imperial rank was automatically awarded a junior fifth rank lower grade court rank when he reached the age of twenty-one. Special treatment for anyone with a fifth rank or above - apart from the rights that their sons had to a high rank when they turned twenty-one, irrespective of ability - is revealed by the generous stipends and retainers they received’
[2]
’The structure of the imperial court was a complex affair. The following chart depicts the basic outline, but each division and ministry contained a hierarchy of officials. Some divisions also included subdivisions. Despite the formality of this structure, the operation and functionality of any particular ministry fluctuated depending on the particular time period. There were also aristocratic families who came to dominate a particular court function through the use of heredity.’
[3]
5.Emperor ’At the apex of the structure was the emperor, whose will was expressed in decrees (mikotonori) and edicts (semmyo). Important decisions, such as those pertaining to appointments and promotions of high-ranking officials, were recommended at meetings of the Council of State but were carried out only with imperial approval. The two codes placed no limitations on imperial authority, thus giving the emperor, legally at least, despotic control.
[1]
4[a]. Council of Kami Affairs’Under the emperor were two councils that had equal standing: the Council of State, generally overseeing secular affairs, and the Council of Kami Affairs, running affairs in the area of kami worship. Although the two councils were organizationally at the same level, the Council of State’s highest minister (the chancellor) held a higher rank than did the highest official of the Council of Kami Affairs. But the chancellor also had some responsibilities that lay outside the bounds of secular administration: He served as the emperor’s guide and teacher and was given the task of harmonizing movements of the world with Chinese principles of yin and yang.’

4[b].1. Chancellorthe chancellor also had some responsibilities that lay outside the bounds of secular administration: He served as the emperor’s guide and teacher and was given the task of harmonizing movements of the world with Chinese principles of yin and yang.’
[4]
3[a] Minister of the Left3.1[a] Central affairs’The Ministry of Central Affairs (the Nakatsukasa-sho) ranked above all other ministries and was the main link between the emperor and the Council of State. Its minister gave advice on numerous court matters, supervised the court chamberlains, and drafted imperial edicts. Under him were ten secretariats, including the Secretariat for the Empress’s Household (Chugushiki).’
[5]
3.2[a] The Ministry of Personnel’The Ministry of Personnel(Shikibu-sho) supervised personnel affairs. Within it were two important bureaus: one for higher learning (Daigaku-ryo) and another for nobles who held a court rank but occupied no office (Sammi-ryo).’
[5]
3.3[a] Civil affairs‘The Ministry of Civil Affairs (Jibu-sho) had two important bureaus: one for Buddhist priests and nuns and aliens (Gemba-ryo) and another for court music (Gagaku-ryo).’
[5]
3.4.[a] Popular affairs‘The Ministry of Popular Affairs (Mimbu-sho) was responsible for administering household registers, taxes, irrigation, paddy fields, and the budget.’
[5]
3[b] Minister of the Right 3[b].1 The Ministry of War‘The Ministry of War (Hyobu-sho) took care of personnel matters pertaining to soldiers and other military affairs.’
[5]
3[b].2 The Ministry of Justice‘The Ministry of Justice (Gyobu-sho) handled legal affairs.’
[5]
3[b].3 Treasury‘The Ministry of the Treasury (Okura-sho) dealt with state property, weights and measures, prices, and related matters.’
[5]
3[b].4 Imperial household‘The Ministry of the Imperial Household (Kunai-sho) managed food, clothing, and personnel problems of the imperial household. Inside each ministry were several, often several tens of, administrative organs of three types: secretariats (shiki), bureaus (ryo), and offices (tsukasa)’
[5]
2.Four senior counselors’Below the chancellor, the minister of the left, and the minister of the right were four senior counselors.
[6]
1 Council of State’s three departments‘Under these six men were the heads of three administrative offices, referred to as the Council of State’s three departments: the Department of Junior Counselors (Shonagonkan), the Department of the Controller of the Left (Sabenkan), and the Department of the Controller of the Right (Ubenkan). The first included three junior counselors authorized to serve as custodians of the imperial and Council of State seals, and the last two were responsible for transmitting imperial orders (senji), distributing orders issued by the Council of State (kampu), and handling communications between the council and its eight ministries.’
[5]
1.1 the Department of Junior Counselors (Shonagonkan)
1.2 the Department of the Controller of the Left (Sabenkan)
1.3 the Department of the Controller of the Right (Ubenkan)
___Other offices___
‘Outside the ministerial structure were a number of important boards and administrative units’
[5]
Censors
‘the Board of Censors (Danjodai) that was engaged in exposing the illegal activities of officials and upholding standards of correct bureaucratic behaviour.’
[5]
Guard units
‘there were the headquarters of the various guard units, beginning with the five that guarded the imperial palace: the gate guards (emon-fu), the left guards (saeji-fu), the right guards (neji-fu), the left military guards (sahyoe-fu), and the right military guards (uhyoe-fu). The central government had, in addition, a right and left bureau of cavalry and a right and left bureau of armories. Other offices outside the eight ministries included two that were responsible for the left and right sectors of the capital.’
[7]
Capital section Dazaifu
‘ Organs of government outside the capital included, first of all, the Dazai headquarters (Dazai-fu) located near the harbor of Na in Kyushu from which the nine provinces of Kyushu, as well as the islands of Iki and Tsushima, were administered. Each of the country’s sixty or more provinces 16 was headed by a governor who usually had under him ten or more districts headed by district supervisors. Each district contained between two and twenty villages (sato) made up of fifty households each. A governor was appointed for a six-year term, but the district supervisors, usually selected from the local gentry, had no fixed term of office. The Taiho administrative code contained no
articles dealing with village heads, but it is assumed that they were influential farmers.’

’the ‘cap rank’ system introduced earlier by Prince Sho¯toku was in theory based, as in China, on merit not birth. However, in practice, and particularly during the Nara period, both rank and position in the Japanese bureaucracy quickly became determined by inherited family status rather than by individual merit’ [1]

’While examinations in China theoretically gave everyone a chance to rise in society, in Japan the university was virtually closed to all but the sons of courtiers. This was because a young man had to hold court rank before he could be appointed to an official post. In effect, all but the very dullest aristocratic sons were assured of bureaucratic office without having to make an effort at the university, though promotion within the bureaucracy depended on diligence and scholarly attainmentsin most cases. [1] ’the examination-based meritocracy of China’s bureaucratic world was not too palatable to the Japanese. This is ironic in view of the prominence of examinations in present-day Japan, but understandable from the perspective of an established elite wishing to safeguard control and stability.’ [2]

’Such exchange took place at two state-run markets (the Eastern and the Western) in the capital, which were centers of a vast commercial network that included markets, ports, and stations in neighboring provinces...

’it was during the age of Nara that Chinese writing led to the appearance of the first real books produced in Japan, the Kojiki and Nihon Shoki chronicles of 712 and 720. These were followed shortly afterwards by the first poetry anthologies, the Kaifuso (Fond Recollections of Poetry) of 751 and the Manyo¯shu¯ (Collection of Ten Thousand Leaves) of 759.

The earliest known written Japanese texts date to the eight century. Although the spoken languages have no relationship Chinese characters were borrowed to enable Japanese to be written ‘Over time the Japanese writing system developed into a complex use of Chinese characters along with two different phonetic scripts to represent the sounds of spoken Japanese. The two phonetic scripts—hiragana and katakana—represented the same sounds but were used in different contexts reflecting, among other things, class and gender.’ [1]

’Moreover, Japanese envoys were then less interested in territorial and military matters than in such cultural activity as acquiring Buddhist and Confucian texts, gathering information on Chinese science and art, and becoming familiar with T’ang methods of political and social control. They seem to have been especially fascinated with Chinese techniques and ideas that would reinforce the foundations of a Nara state headed by an emperor whose authority was both secular and religious.’ [1]

‘Inouye Kaoru observed that Doji, a Buddhist priest who went to China in 702 and returned in 718, brought back a copy of the recent translation that the compilers of the Nihon shoki had seen.« Historians are therefore in general agreement that the Nihon shoki item concerning the introduction of Buddhism contains additions and embellishments made by later editors. And yet it cannot be denied that King Songmyong of Paekche actually sent Buddhist images and texts to the Yamato king around the middle of the sixth century and that this was an important event in the early history of Japanese Buddhism.’ [1]

The Chinese calender was known and studied in Japan from the 6th century ’Written records were now used to carry out government functions; Buddhism was enthusiastically embraced; and Chinese technology stimulated such diverse fields as calendar making...Missions from Japan to China no longer sought only luxury goods, or even Chinese recognition of a Japanese ruler’s authority, but sophisticated forms of learning as well.’ [1] but does not appear to have been officially adopted until the Chinese Hsuan-ming calendar that was brought by an embassy in 859 and remained the official calendar of Japan, with growing inaccuracy, from 862 to 1684.’ [2]

The first minting occurred in 708 CE with silver and copper coins. [1] . "By the late seventh century, a few silver coins were issued, but they did not have a large circulation." The minting of 708 CE was modeled on the Tang currency. [2] "Copper cash was known as Wado-kaichin, and four were the equivalent of a silver coin." [2] Gold coins minted in 760 CE, one gold coin worth 100 copper mon. [2] "In 765, further minting of copper coins only was instituted at Nara." [2] "...the twelve imperial coins (kocho junisen) of Nara times, and from late Heian’ [3] ’In the quest for recognition as a civilized society by the seemingly advanced countries of the adjacent continent, Japanese leaders followed the example of Korea and China in minting the government’s own coinage, despite the apparent absence of a vigorous domestic commerce in need of money currency. The leaders also probably hoped thereby not only to encourage and facilitate such commerce as existed, but perhaps as well to reap the profits that currency manipulation made possible. The first minting was the well-known Wado kaiho coin of 708, which was produced just seven years after the adoption of theTaiho code of 701. Eleven new coins followed in the next two and a half centuries (until 958), eight of them during the Heian years. Minting at various places but mainly in copper producing regions like Suo and Nagato, they were mostly made of brass, but some were silver, and there was one gold coin, the Kaiki shoho coin of 760."

’Typical defenses included a rampart, a ditch, and a palisade.’ [1] ’Up to the beginning of the feudal era, three forms of fortifications were built, according to archaeologists. The grid-pattern city form was inspired by Chinese planning precedents, and included gates or walled enclosures. Mountain fortresses appear to be an indigenous form, and were typical of remote areas. Plateaus or plains often utilized the palisade, a semi-permanent defense. Typical defenses included a rampart, a ditch, and a palisade. Grid-pattern cities were surrounded by walls that served as a demarcation point rather than as true protection, and eventually such barriers disappeared. Remains of mountain fortresses found in northern Kyushu were a more effective means of protection, and may have belonged to ancient kingdoms that ruled parts of Japan in early times. Palisades were often constructed in the northeastern areas of the main island of Honshu. Although excavations have revealed only partial remains of such structures, they are significant since they offer prototypes for medieval fortifications.’ [1] "Unlike the walled towns of China and Korea, fortified places in Japan tended to be isolated military outposts. These yamashiro (mountain castles) were hilltop fortresses consisting only of wooden stockades, gates and towers, joined to one another across valleys and peaks to form a complex defensive arrangement. With no stone or mudbrick walls to batter down, these castles were almost always overcome by infantry assault, often supported by arson attacks launched by fire arrows." [2]

With no stone or mudbrick walls to batter down, these castles were almost always overcome by infantry assault, often supported by arson attacks launched by fire arrows." [1] "Up to the beginning of the feudal era, three forms of fortifications were built, according to archaeologists. The grid-pattern city form was inspired by Chinese planning precedents, and included gates or walled enclosures." [2]

’Mountain fortresses appear to be an indigenous form, and were typical of remote areas’ [1] "Unlike the walled towns of China and Korea, fortified places in Japan tended to be isolated military outposts. These yamashiro (mountain castles) were hilltop fortresses consisting only of wooden stockades, gates and towers, joined to one another across valleys and peaks to form a complex defensive arrangement. With no stone or mudbrick walls to batter down, these castles were almost always overcome by infantry assault, often supported by arson attacks launched by fire arrows." [2]

From Early Yayoi. [1] ’By the Yayoi Period (50-250 CE) iron tools became more plentiful, as is evidenced by advances in woodworking technologies. By the last century of the Yayoi, iron-working technologies spread quickly across the central region of Japan from west to east. Over the course of the next several hundred years, iron completely replaced stone as the mineral of choice. Iron swords, armor, and arrowheads came to occupy prominent places in the tombs of the Kofun period. From that time onward, iron and its alloy with carbon, steel, were Japan’s pre-eminent proto-industrial metals.’ [2]

"unlike the crossbows that were used as anti-personnel weapons, there does not appear to be any record of trebuchet use in Japan, simply because the siege situation did not demand it." [1] ‘it is not until 1468[CE] that we find an unambiguous reference to the use of traction trebuchets in Japan.’ [2]

although single piece bows were used in earlier times, and could technically have been used, the composite bow had been standard military equipment since the 9th century CE.
crossbows long used in China were used up to the 11th CE century in Japan. [1] "As no Japanese oyumi (siege crossbow) has survived, it is impossible to know exactly what one looked like or how it was operated. Certain records make tantalising reference to them being different from Chinese varieties, although this may just be an expression of national pride. It is, however, well substantiated that, in contrast to the predominant Chinese practice, the Japanese crossbows were used for throwing stones as much as for firing arrows." [2]

the composite bow had been standard military equipment since the 9th century CE but was most likely used before then. From the Kamakura period, bows were constructed in layers utilizing bamboo slats for added strength and flexibility. The core of the bow was made of stiff wood and was combined with laminated pieces of bamboo.’ [1]

‘First used by the early Kamakura period, the naginata is closest to a European glaive in form, with an elongated shaft, and a single-edged blade curved more than that of a Kamakura-period Japanese tachi. Most likely, the naginata was based upon similar weapons introduced from China by 300 C.E. which have been unearthed in graves.’ [1]

daggers were used in non-military contexts but I couldn’t find a specific reference to daggers in a military context.
Horses from the 8th [CE] century cavalry played an often vital part in Japanese . The importance place about cavalry shifted throughout time falling in and out of popularity but always remaining present. [1] ‘Horsemanshipwas central to bushi identity, distinguishing the professional warrior from those who served him - and fought beside him, on foot. As we have seen, the horse was one of the two tools that defined the “way of bow and horse,” which defined the samurai. [2]

’Shields were commonly used in nearly all military contexts in Japan, beginning with prehistory. Chinese dynastic histories include descriptions that indicate shields were in use by the third century in Japan...From the Nara period to the early medieval period, military shields were standing wooden barriers about eye-level in height and roughly the width of human shoulders... They were attached to poles, or feet, which were hinged so that the support could be collapsed and stored or transported flat. Approximately one and a half meters tall and less than half a meter wide, mostly such shields were made of several planks joined vertically. Although shields could withstand more force if each was made from a single board, this was the exception rather than the rule. Protective substances such as lacquer could also prolong the life of such standing shields.’ [1]

’the keiko wrapped around the wearer’s body and was fastened up the front with ties. At first there were two types, both made up of ’steps’ of scales laced horizontally together into boards; one kind was held together with leather straps running down the outside of the steps, and the other with a more conventional under-over lacing of braided cord or leather... the popularity of scale armour began to predominate in the 6th and 7th centuries. ’ [1] "The earliest armor used in Japan, as elsewhere, was padded or made of scales or rings sewn on cloth. The armor found in the grove mounds of prior to 400 B.C. is made by riveting together small pieces of iron to make helmets and cuirasses. Some of the latter give quite the effect of plate armor but are built up of small pieces. By the 10th century, the earliest time of which we have definite knowledge, it had assumed a characteristic form which it retained until armor was abandoned in the middle of the 19th century. A Japanese suit, fig. 78, consists of a helmet, kabuto, usually made of a large number of narrow plates riveted together with raised edges at the joints. It has a small peak, maizashi, in front and a wide neck guard, shikoro, made of strips of steel or of scales of leather or steel laced together with heavy silk or leather cords. One or more of these pieces is turned back in front to form ear guards, fukigayeshi. The front is usually decorated with two horn-like pieces, kuwagata, representing the leaves of a water plant; between them is an ornament, maidate, corresponding to the European crest. The face is covered by a steel mask, menpo, to which a laminated neck guard, yodare-kake, is attached. There are five varieties of menpo - covering the entire face - all of the face below the eyes - the forehead and cheeks only - and two for the cheeks and chin only. Of these, the second is much most used. A gorget, nodowa, was sometimes worn but was not considered as a regular part of the suit. The body was enclosed in a corselet, do, made of plates or strips laced together with silk or leather cords. It either opened at the side, do-maru, or at the back haramaki-do. Attached to it were shoulder pieces, watagami, from which it hung. The taces, kusazuri, made of strips laced together, hung from the do. Under these was worn an apron, hai-date, of brocade covered with mail or mixed plate and mail. The legs below the knee were protected by close fitting greaves, sune-ate, of plate; and the feet were covered with bearskin shoes, tsurumaki, or with mail or plate tabi. The arm guards, kote, were brocade sleeves covered with mixed plate and mail. They usually ended in guantlets which covered only the backs of the hands and thumbs. Mail guantlets were rare but were sometimes used. Large guards, sode, were hung on the shoulders. They were either single plates, two hinged together or made up of strops or rows of scales laced together." [2] "The Japanese made more varieties of mail than all the rest of the world put together."

’the last pieces of armour were for the forearms and shins. very few have survived unscathed, but enough have to give us some ideas as to their construction. there were generally two types: those formed like tubes, of one or two semi-circular plates and those made of splints. usually attached to the forearm guards were flat metal plates or a lamellar deffence fo rthe back of the hand.

From the 5th century a rounder form of helmet called mabizachi-tsuke kabuto (’visor-attached helmet’), with a ’baseball cap’ flat visor, was also worn with the tanko. this was an important style, modeled after the helmets of the Korean and Chinese warriors encountered on the continent. Such helmets were made en suite with the later lamellar armours, but examples have been found in the same tombs as tanko. most had a cup-shaped crest holder supported by a bronze tube, presumably for some sort of plume.
