The Kofun period (古墳時代, Kofun-jidai^?) is an era in the history of Japan from around 250 to 538. The word kofun is Japanese for the type of burial mounds dating from this era. The Kofun period follows the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes referred to collectively as the Yamato period.

Generally, the Kofun period is divided from the Asuka period for its cultural differences. The Kofun period is illustrated by an animistic culture which existed prior to the introduction of Buddhism. Politically, the establishment of the Yamato court, and its expansion as allied states from Kyūshū to the Kantō are key factors in defining the period. Also, the Kofun period is the oldest era of recorded history in Japan. However, as the chronology of the historical sources are very much distorted, studies of this age require deliberate criticism and the aid of archaeology.

The archaeological record, and ancient Chinese sources, indicate that the various tribes and chiefdoms of Japan did not begin to coalesce into states until 300, when large tombs began to appear while there were no contacts between western Japan and China. Some describe the "mysterious century" as a time of internecine warfare as various chiefdoms competed for hegemony on Kyūshū and Honshū.^[1]

[edit] Kofun tombs

See also: Kofun

Kofun (古墳, "old tomb") are defined as the burial mounds built for the people of the ruling class during the 3rd to 7th centuries in Japan.^[2] The Kofun period takes its name from these distinctive earthen mounds which are associated with the rich funerary rituals of the time. The mounds contained large stone burial chambers. Some are surrounded by moats.

Kofun came in many shapes, with round and square being the simplest. A distinct style is the keyhole-shaped kofun, with its square front and round back. Kofun range in size from several meters to over 400 meters in length.

[edit] Development of Kofun

The oldest Japanese Kofun is said to be Hokenoyama Kofun located in Sakurai, Nara, which dates to the late 3rd century. In Makimuku district of Sakurai, earlier keyhole kofuns (Hashihaka Kofun, Shibuya Mukaiyama Kofun) were built around the early 4th century. The trend of the keyhole kofun first spread from Yamato to Kawachi (where gigantic kofun such as Daisenryō Kofun), and then throughout the country (except for Tohoku region) in the 5th century. Later that century, keyhole kofuns were also built in the Gaya confederacy of the Korean peninsula.^{[citation needed]} Whether the keyhole kofun in Gaya was for a local chieftain influenced by Japanese culture or for an immigrated Japanese aristocrat is also debated.

Keyhole kofun disappeared later in the 6th century, probably because of the drastic reformation which took place in the Yamato court; Nihonshoki records the introduction of Buddhism at this time. The last two great kofun are the Imashirozuka kofun (length: 190m) of Osaka, which is believed by current scholars to be the tomb of Emperor Keitai, and the Iwatoyama kofun (length: 135m) of Fukuoka which was recorded in Fudoki of Chikugo to be the tomb of Iwai, the political archrival of Keitai.

[edit] Yamato court

While conventionally assigned to the period from 250 AD, the actual start of Yamato rule is disputed. The start of the court is also linked with the controversy of Yamataikoku and its fall. Regardless, it is generally agreed that Yamato rulers possessed keyhole kofun culture and held hegemony in Yamato up to the 4th century. The regional autonomy of local powers remained throughout the period, particularly in places such as Kibi (current Okayama prefecture), Izumo (current Shimane prefecture), Koshi (current Fukui and Niigata prefecture), Kenu (northern Kantō), Chikushi (northern Kyūshū), and Hi (central Kyūshū); it was only in the 6th century that the Yamato clans could be said to be dominant over the entire southern half of Japan. On the other hand, official diplomatic relations with the Korean peninsula and China were likely to have been concentrated in Yamato, as Chinese and Korean history recorded no other rival provinces in the Japanese archipelago. Yamato's relationships with foreign states is likely to have begun in the late 4th century, according to the Seven-Branched Sword inscription.

The Yamato polity, which emerged by the late 5th century, was distinguished by powerful clans (豪族: Gōzoku). Each clan was headed by a patriarch (氏上: Ujikami) who performed sacred rites to the clan's kami to ensure the long-term welfare of the clan. Clan members were the aristocracy, and the kingly line that controlled the Yamato court was at its pinnacle.

The Kofun period of Japanese culture is also sometimes called the Yamato period by some Western scholars, since this local chieftainship arose to become the Imperial dynasty at the end of the Kofun period. Yamato and its dynasty however were just one rival polity among others throughout the Kofun era. Japanese archaeologists emphasise instead the fact that in the early half of the Kofun period other regional chieftainships, such as Kibi were in close contention for dominance or importance. The Tsukuriyama Kofun of Kibi is the fourth largest kofun in Japan.

The Yamato court ultimately exercised power over clans in Kyūshū and Honshū, bestowing titles, some hereditary, on clan chieftains. The Yamato name became synonymous with all of Japan as the Yamato rulers suppressed the clans and acquired agricultural lands. Based on Chinese models (including the adoption of the Chinese written language), they started to develop a central administration and an imperial court attended by subordinate clan chieftains but with no permanent capital. Japan's rulers of the time even petitioned the Chinese court for confirmation of royal titles.

The Yamato court had ties to the Gaya confederacy, called Mimana in Japanese. There is archaeological evidence from the Kofun tombs, which show similarities in form, art, and clothing of the depicted nobles. Based on the Kojiki and the Nihonshoki, Japanese kokugaku historians claimed Gaya to be a colony of the Yamato state, a theory that is now widely rejected. More likely all these states were tributaries to the Chinese dynasties to some extent. However, Chinese scholars point to the Book of Song of the Liu Song Dynasty, written by the Chinese historian Shen Yue (441-513), presenting the sovereign of Japan as the suzerain of the Gaya Confederacy.

[edit] Territorial expansion of Yamato

In addition to archaeological findings indicating a local monarchy in the Kibi Province as an important rival, the legend of the 4th century Prince Yamato Takeru alludes to the borders of the Yamato and battlegrounds in the area. A frontier was obviously somewhere close to the later Izumo province (the eastern part of today's Shimane prefecture). Another frontier, in Kyūshū, was apparently somewhere north of today's Kumamoto prefecture. The legend specifically states that there was an eastern land in Honshū "whose people disobeyed the imperial court", against whom Yamato Takeru was sent to fight. That rivalling country may have been located rather close to the Yamato nucleus area itself, or relatively far away. The today Kai province is mentioned as one of the locations where prince Yamato Takeru sojourned in his said military expedition.

Northern frontier of this age was also explained in Kojiki as the legend of Shido Shogun's (四道将軍: Shoguns to four ways) expedition. Out of four shoguns, Ōbiko set northward to Koshi and his son Take Nunakawawake set to eastern states. The father moved east from northern Koshi while the son moved north on his way, and they finally met at Aizu(current western Fukushima). Although the legend itself is not likely to be a historical fact, Aizu is rather close to southern Tōhoku, where the north end of keyhole kofun culture as of late 4th century is located.

[edit] Ōkimi

During the Kofun period, a highly aristocratic society with militaristic rulers developed.

The Kofun period was a critical stage in Japan's evolution toward a more cohesive and recognized state. This society was most developed in the Kinai Region and the easternmost part of the Inland Sea. Japan's rulers of the time even petitioned the Chinese court for confirmation of royal titles.

While the rulers' titles are diplomatically King, they locally titled themselves as Ōkimi(Great King) during this period. Inscriptions in two swords, Inariyama Sword and Eta Funayama Sword had records of Amenoshita Shiroshimesu(治天下;"ruling of Heaven and Earth") and Ōkimi(大王) in common, to be a ruler that the bearers of these swords were subjected to. It reveals that rulers of this age also grasped religious authorities to justify their thrones through heavenly dignities. The title of Amenoshita Shiroshimesu Okimi was used up to 7th century, until being replaced by Tenno.

[edit] Clans of the Yamato Court

Many of the clans and local chieftains that made up the Yamato polity claimed descent from the imperial family or other tribal Gods (Kami). The archeological evidence for such clans is found in the Inariyama sword, on which the bearer recorded the names of his ancestors to claim its origin to Ōbiko(大彦) who was recorded in Nihon Shoki as a son of Emperor Kōgen. On the other hand, there are also a number of clans having origins in China or the Korean peninsula.

In the 5th century, the Kazuraki clan(葛城氏), descending from the legendary grandson of Emperor Kōgen, was the most prominent power in the court and intermarried with the imperial family. After Kazuraki declined in the late 5th century, the Ōtomo clan(大伴氏) temporarily took its place. When Emperor Buretsu died with no apparent heir, it was Otomo no Kanamura who recommended Emperor Keitai, a very distant imperial relative who resided in Koshi (current Fukui Prefecture), as the new monarch. However, Kanamura resigned due to the failure of his diplomatic policies, and the court was eventually controlled by the Mononobe (物部氏) and Soga clans (蘇我氏) at the beginning of the Asuka period.

[edit] Kofun society

[edit] Torai-Jin

Chinese and Korean immigrants who were naturalized in ancient Japan were called "Torai-Jin" (渡来人). They introduced many aspects of Chinese culture to Japan; valuing their knowledge and culture, the Yamato government gave preferential treatment to Torai-Jins. This is also likely due to the fact that many in the Yamato government are implied to have Chinese or Korean roots themselves, and thus may have felt some kinship towards these Torai-Jin.^{[citation needed]}

[edit] Chinese migration

Many important figures were also immigrants from China. Chinese immigrants also had considerable influence according to the Shinsen-Joujouroku (新撰姓氏録),^[3] which was used as a directory of aristocrats. Yamato Imperial Court had officially edited the directory in 815, and 163 Chinese clans were registered.

According to Nihongi, the Hata clan, which was composed of descendants of Qin Shi Huang^[4], arrived at Yamato in 403 (the fourteenth year of Oujin) leading the people of 120 provinces. According to the Shinsen-Shoujiroku, the Hata clan were dispersed in various provinces during the reign of Emperor Nintoku and were made to undertake sericulture and the manufacturing of silk for the court. When the finance ministry was set up in Yamato Court, Hata Otsuchichi (秦大津父) was in charge of accounts as a minister of it.

In 409 (twentieth year of Oujin), Achi-no-Omi ancestor of the Yamato-Aya clan which was composed of also arrived with the people of 17 districts. According to the Shinsen-Shoujiroku, Achi obtained the permission to establish the Province of Imaki. The Kawachi-no-Fumi clan, descendants of Gaozu of Han, introduced aspects of Chinese writing to the Yamato court.

The Takamuko clan is a descendant of Cao Cao. Takamuko-no-Kuromaro was a center member of Taika Reform.^[5]

[edit] Korean migration

Among the many Korean immigrants who settled in Japan beginning in the 4th century, some came to be the progenitors of Japanese clans. According to Nihongi, the oldest record of a Silla immigrant is Amenohiboko, a legendary prince of Silla who settled to Japan at the era of Emperor Suinin, perhaps around the 3rd or 4th century. Ironically, Amenohiboko is described in Nihongi as a maternal predecessor of Empress Jingū, whose controversial legend says that she defeated Silla. This is highly inconsistent, as Jingū is said to have lived in the 2nd and 3rd centuries, and she is supposed to have died in 269 AD.

On the other hand, Korean immigrants also include the Baekje royal family. King Muryeong of Baekje was born in Japan in 462, and left a son who settled there. In Emperor Ōjin's reign, Geunchogo of Baekje granted a large number of gifts and scholars to the Japanese emperor.^[6] The elements of Chinese culture introduced to the Yamato Imperial Court are very important.^[7] According to the book, Shinsen shoji roku compiled in A.D.815, a total 154 out of 1,182 noble families in the Kinai are on Honshu Island were regarded as people with Korean genealogy. The book specifically mentions 104 such families from Baekje, 41 from Goguryeo, 6 from Silla, and 3 from Gaya. ^[8] They might be families that moved to Japan between the years A.D.356-645.

[edit] Language

Main article: Japanese language

Chinese, Korean and Japanese wrote accounts of history mostly in Chinese characters, making original pronunciations difficult to trace.

While writing was largely unknown to the indigenous Japanese of this period, the literary skills of foreigners seem to have increasingly become appreciated by the elites of some Japanese regions. The Inariyama sword, made in either China (tentatively dated 471 or 531) contains Chinese-character inscriptions in styles used in China, leading to speculation that the owner, though claiming to be a Japanese aristocrat, might possibly actually have been an immigrant.^[9]

[edit] Introduction of equine culture to Japan

Chinese chronicles make note that the horse was absent on the islands of Japan and they are first noted in the chronicles during the reign of Nintoku, most likely brought by China and Korean immigrants. The horse is one of the treasures presented when the king of Silla surrenders to Empress Jingū in the mythological record of Nihonshoki.^[10] Irrigation, sericulture, and weaving were also brought to Japan by China and Korean immigrants who are mentioned in the ancient Japanese histories. For instance, Chinese immigrant's Hata clan told Japan about sericulture.

The cavalry wore armour, carried swords and other weapons, and used advanced military methods like those of north-east Asia. Evidence of these advances is seen in funerary figures (called haniwa; literally, clay rings), found in thousands of kofun scattered throughout Japan. The most important of the haniwa were found in southern Honshū—especially the Kinai region around Nara—and northern Kyūshū. Haniwa grave offerings were made in numerous forms, such as horses, chickens, birds, fans, fish, houses, weapons, shields, sunshades, pillows, and male and female humans. Another funerary piece, the magatama, became one of the symbols of the power of the imperial house. Much of the material culture of the Kofun period is barely distinguishable from that of the contemporaneous southern Korean peninsula, demonstrating that at this time Japan was in close political and economic contact with continental Asia (especially with the southern dynasties of China) through Korea. Indeed, bronze mirrors cast from the same mould have been found on both sides of the Tsushima Strait.

[edit] Towards Asuka period

The Kofun period gave way to the Asuka period in mid-6th century AD by the introduction of Buddhism. The religion was officially introduced at the year 538, and this year is traditionally set for the epoch of the new period. Also, after the reunification of China by Sui Dynasty later in this century, Japan was deeply influenced by Chinese culture and consequently entered into a new cultural era.

[edit] Relations between the Yamato court and the Korean kingdoms

According to the Book of Song, a Chinese emperor appointed five kings of Wa to the position of ruler of Silla in 421.^[11] Japan of the Kofun period was very positive towards the introduction of both Chinese culture and Korean culture. [8]. Chinese and Korean immigrants played an important role in introducing elements of both Chinese civilization and Korean civilization to early Japan.[9].

The special burial customs of the Goguryeo culture had an important influence on other cultures in Japan.^[12] Decorated tombs and painted tumuli which date from the fifth century and later found in Japan are generally accepted as Korean peninsula exports to Japan. The Takamatsuzuka Tomb even has paintings of woman dressed in distinctive Clothes written in wall painting of Goguryeo and Tang Dynasty.^[13]　[14]　And, the astronomy figure of China was being written.

[edit] Chinese and Korean records

According to the Book of Song, of the Liu Song Dynasty, the Emperor of China bestowed military sovereignty over Silla, Imna, Gaya, Jinhan, and Mohan on King Sai of Wa. After the death of King Kō of Wa, his younger brother Bu acceeded to the throne; King Bu requested to have Baekje added to the list of protectorates included in the official title bestowed upon the King of Wa by mandate of the Emperor of China, but his title was only renewed as "Supervisor of All Military Affairs of the Six Countries of Wa, Silla, Imna, Gara, Jinhan, and Mohan, Great General Who Keeps Peace in the East, King of the Country of Wa."^[15]

According to the Book of Sui, Silla and Baekje needed assistance from Yamato Japan to continue military campaigns that had run out of steam.^[16] According to the Samguk Sagi (Chronicles of the Three Kingdoms), Baekje and Silla sent their princes as hostages to the Yamato court in exchange for military support to continue their already-begun military campaigns; King Asin of Baekje sent his son Jeonji in 397^[17] and King Silseong of Silla sent his son Misaheun in 402.^[18][19]

According to the Book of Sui, Silla and Baekje greatly valued relations with Wa (Japan) of the Kofun period, and the Korean kingdoms made diplomatic efforts to maintain their good standing with the Japanese.^[16]
