The Kofun period is commonly defined by the emergence and spread of mounded tombs, from which derive the word Kofun meaning "old tumulus"(Ko (=ancient) + fun(=tumulus)). [1] [2] The most visually prominent type of these mounds is the monumental keyhole shaped tomb that spread from northern Kyushu to Kanto from the middle of the third century onwards. [3] [4] The large-sized keyhole shaped tombs have been interpreted as the burials of regional leaders. [2] Most of the largest keyhole shaped tumuli are distributed in the present-day Nara basin and Osaka plain of the Kansai region, which could have played a prominent political role in Japan during the Kofun period. [1] The Kofun period is sub-divided into three sub-periods: Early (250-400 CE), Middle (400-475 CE), and Late (475-710 CE). [5] This sub-division is based on changes in tomb structures and their assemblages, in settlement patterns and in ruling dynasties. In fact, the seat of the political centre shifted from Miwa, during the Early Kofun, to Kawachi, in the Middle Kofun, and finally to Asuka in the Late Kofun period. [6]
Population and political organization
The Early Kofun period is characterized by the spatial distribution of many contemporaneous large keyhole shaped tumuli, which represent the presence of several different polities and regional leaders. [1] [7] In this period, bronze mirrors, beads of jasper and green tuff, haniwa vessels, iron weapons and tools were deposited in the large mounded tombs, which likely hosted the burial of a regional chief. [8] The burial chambers were either cists made of slate stone in oblong plan or vertical pitsdug on the top of the mound. [9] The political centre was Miwa, in the south-eastern Nara basin. Thi centres incorporated the Makimuku district, which housed the large Hashikaka keyhole-shaped tomb (280 m long), considered to be the burial place of the queen Himiko. [5] The power was held at Miwa by the Sujin dynasty. [10] [11]
The Middle Kofun period is characterized by the spread of large keyhole-shaped mounds in the Osaka Plains.The grave assemblage met substantial change: bronze mirrors and fine beadstone objects were no longer deposited. [6] [12] Instead, the amount of iron deposited in the tombs in form of weapons and/or tools increased. [6] Beads, armlets and talismans begant to be made of talc, and they were not only deposited in burials but also used in landscape rituals. [13] [14] [15] Horse trappings, gilt-bronze ornaments and gold jewellery began being deposited in the grave assemblage of large burial mounds. [6] In this period, the power was exerted by the Ojin dynasty in the centre of Kawachi, in the east central Osaka prefecture. [6]
In the Late Kofun Period the size of the burial mounds decreased significantly and the construction of large keyhole-shaped tumuli ceased, except for the Kanto region. Thereafter, the tumuli of the regional leaders were downsized and built in a rectangular and square shape. [16] [17] [18] This decline was followed by the proliferation of clusters of small round tumuli called "packed tumuli clusters". [19] They have been interpreted as the result of the emulation of the chiefly habits by powerful extended family-scale groupings. [20] In this period were also introduced the corridor-chamber tombs and the cliff-cut cave tombs. [21] The power was held by the Keitai dinasty in the centre of Asuka, in southern Nara prefecture. [22] The introduction of Buddhism in 552 CE, determined a new Buddhism-based culture in the area. [21]
We have estimated the population of Kansai to be between 150,000 and 200,000 people in 300 CE, and between 1.5 million and 2 million by 500 CE. An estimated 16.8% of the Japanese population lived in Kansai from 250-599 CE. [23] [24]

[250 CE ➜ 537 CE]

The Kofun period is generally divided into three sub-periods: Early (ca. 250 - 400 CE), Middle (ca. 400 - 475 CE), and Late (ca. 475-710 CE). [1] [2] The last part of the Kofun period is often designated by the historias as Asuka period (ca. 538 - 710 CE), which begins with the introduction of writing and of Buddhism into the country. [3] [4]
The Kofun period is subdivided into three sub-periods: Early (250-400 CE), Middle (400-475 CE), and Late (475-710 CE). [1] This subdivision is based in change of tomb structures their assemblage, of settlement patterns and of ruling dynasties. In fact, the political centre shifts from Miwa, during the Early Kofun, to Kawachi (Middle Kofun), and finally to Asuka in the Late Kofun. [5]

Supracultural Entity:
Initial Kofun Package

Mizoguchi (2013) characterizes one broad regional cultural horizon: the Initial Kofun package, which spread from northern Kyushu to Kanto (see Figure 1 below) [1] .This homogeneous cultural horizon is characterised by the prevalence of keyhole-shaped tumulus containing a set of grave goods such as bronze mirrors, bronze and iron tools and weapons [2] .

Centers in Kyushu (south west Japan) and Nara-Osaka-Kobe area until 600 CE when unified by a bureaucracy and Buddhism. So 250-599 CE = Nara-Osaka-Kobe, whilst 600-710 CE = Nara-Osaka-Kobe + Kyushu (south west Japan).
"The other main centre was in the fertile, but circumscribed, alluvial systems of the Nara-Osaka-Kobe area, where status differentiation appears instead to have been based on hereditary ritual authority. The fusion of these geographical power-bases had occurred by about A.D. 600, by which time a well-developed bureaucracy in the Nara basin was exerting its authority and promoting Buddhism as a unifying ideology for the new regime, thus replacing the ritual authority vested in earlier individual rulers." [2]

"From about A.D. 300 until the capital was moved to Kyoto in the late 8th century, the Nara basin definitely was the centre of sociopolitical development in Japan." [3]
"it is difficult to see any evidence for a political unification of a large part of Japan as early as A.D. 369, or shortly thereafter. Yamao (1977) argues, on documentary grounds, that unification was not achieved until about A.D. 531." [4]
"the administrative devices of the central state in the Nara were imported from the continent in order to consolidate the power of that state vis a vis the competing polities in the surrounding areas within Japan." [4]
There is not a unique polity in this period. The political landscape appears fragmented into a variety of competing chiefdoms. The most important political centres in this period are Miwa, Kawachi and Asuka respectively in the Early, Middle and Late Kofun period [5] .

"Tomb-era villages were quite different from their Yayoi predecessors. ... Villages might range from ten to sixty or more pit dwellings, along with several storehouses, and residences might be grouped in units of two or three, suggesting that they contained extended families. In larger settlements, archaeologists have uncovered the remains of sizable wooden structures, sometimes surrounded by a moat or stone walls." [1] There were apparently fewer moats in the Kofun era compared to the Yayoi. According to Kenichi Saski "the new age was also marked by the disappearance of moats enclosing settlements" although "influential people appeared, who could maintain larger storehouses ... these influential people resided within moated enclosures together with ordinary residences. In the Kofun era, settlements were no longer enclosed by moats, but elites began to reside in mansions, enclosed by moats and spatially distinct from ordinary settlements." [2]

Military use of Metals

Tatara furnaces, or versions thereof, existed since 300 BCE. Not sure when this steel was first produced. It is unlikely the best steel was produced from the very earliest times. Asuka period seems likely. "If black sand was used it would contain hypter-eutectoid steel (carbon content 1.2-1.7 percent) called tama hagane and pieces of iron with a lower carbon content (less than 0.8 percent). The tama hagane was the first quality steel used in swords." [1] References that support tamahagane steel being better than the first steels produced in Japan: "Present study elucidates that the tatara iron and its manufacturing procedure gives distinctive features to Japanese swords which is different from ordinary steel. It is also notable that Japanese swordsmith utilized lath martensite without knowing details about it." [2] Tamahagane steel (metal investigated was crafted by a modern swordsmith) has been "investigated with optical microscopy, scanning electron microscopy and electron probe micro analysis methods. Microstructures have been found to be a combination of ferrite and pearlite with a lot of nonmetallic inclusions." [3]

’The establishment of Chinese provinces in the northern Korean Peninsula conveyed knowledge of bronze and iron closer to the Japanese islands, and with Yayoi bronze spears, halberds, swords, mirrors, and bells appeared. In each case, the imported items were transformed by local bronze casters into forms more suited to local tastes and requirements. Thus the weapons were enlarged and broadened.’ [1]

"Slings, used to hurl fist-sized rocks or spheres of clay shaped roughly like miniature rugby balls, also appeared during the Yaoi age, distributed in a geographic pattern that suggests mutually exclusive regional preferences for the sling or the bow." [1]

"Instead, without ready access to supplies of bone and horn, the Japanese fashioned their bows from wood or from laminates of wood and bamboo. The earliest designs were of plain wood ... " [1] "The earliest arrowheads made by iron appeared during Middle Yayoi, and almost all of them are from northern Kyushu. The arrowheads in Kyushu were 3-4 cm long and shaped like a narrow triangle with a vault-shaped base. This shape is the traditional shape of stone arrowheads." [2]

Spears (small, could be thrown?) ’The sizes and shapes of spears cast in middle Yayoi Japan, moreover, suggest that they had a ritual function. These, in contrast with the small spears imported from Korea in the early Yayoi period, ranged in length from fifty to ninety centimeters, to large and unwieldly for combat. Some were placed in graves as ritual objects that symbolized authority and power, but the longest were buried elsewhere, as if for some religious purpose.’ [1]

Gunpowder Siege Artillery:

before use of gunpowder in Japan


Crossbow known and used in Japan sometime after the invention in China (from date not stated) "but neither the ritsuryo armies nor the bushi appear to have developed much interest in it, preferring to rely instead on the long bow. The ritsuryo military statutes provided for only two soldiers from each fifty-man company to be trained as oyumi operators, and no later source indicates that this ratio was ever increased. Hand-held crossbows and crossbowmen are not mentioned in the statutes at all." "The bow staves of Chinese crossbows were composites of wood, bone, sinew and glue ... But, as we have observed, the Japanese lacked supplies of animal products, and fashioned their bows from wood and bamboo instead, which required that the weapons be long. Manufacturing crossbows with composite bow staves of wood and bamboo comparable in length to those of regular bows would have resulted in a weapon too unwieldy to be practical". However some crossbows were imported. [1]

Composite Bow:
absent

"Compound or composite bows of the sort favored on the Asian continent - made by laminating together layers of wood, animal tendon and horn - were known in Japan by the late ninth century, but never widely adopted. Instead, without ready access to supplies of bone and horn, the Japanese fashioned their bows from wood or from laminates of wood and bamboo. The earliest designs were of plain wood ... " [1] "These first compound bows, called fusetake yumi, featured a single strip of bamboo laminated to the outside face of the wood, using a paster (called nibe) made from fish bladders. Sometime around the turn of the thirteenth century, a second bamboo laminate was added to the inside face of the bow, to create the sammai uchi yumi. In the fifteenth century, two additional bamboo slats were addeded to the sides, so that the wooden core was now completely encased, producing the shiochiku yumi. The higo yumi used for traditional Japanese archery today appeared sometime during the seventeenth century." [2]

‘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] According to one military historian, warriors of the Land of Wa (Japan) mentioned by early Han annals used halberds.
