The Kofun system is a social order seen in the construction of stylized Kofuns, particularly Zenpokoenfun that appeared in the early Kofun period of Japan. It is believed to represent a new level of social complexity and the advent of the Yamato Kingship
The concept was proposed in 1991 by Archaeologist Hiroshi Tsuide. In addition, Kazuo Hirose and Yoshiro Kondo have proposed similar concepts under the name of anterior-posterior tomb state and anterior-posterior tomb order, respectively, but the emphasis of the arguments differs among the theorists, and there are conflicting opinions, especially from the perspective of state formation theory.
Hiroshi Tsuide has argued that the construction of the Hashihaka Kofun in Sakurai City, and other stylized anterior-posterior round tombs marked the beginning of the Kofun period, by which time there was already a state-level society. He argued that the centralized political order as seen in the formulation of the funerary system should be called the anterior-posterior mound system. [1] [lower-alpha 1]
Kazuo Hirose has argued that the forward and backward circle mounds developed in various parts of the Japanese archipelago and are characterized by three points: visibility as a "showing kingship," uniformity in shape, and hierarchy manifested in the scale of the mounds. The Yamato Kingship was the center of a social network, or what should be called the "anterior-posterior mound nation. According to Hirose, the "anterior-posterior mound nation" is defined as "a community of interest of the chiefdoms operated by the Yamato regime with commonality in terms of territory, military rights, diplomatic rights, and ideology. It also states that there is a hierarchy between the anterior and posterior tombs, and that the anterior and posterior tombs are the tombs of politically inferior secondary members. [3]
Yoshiro Kondo explains the historical significance of the formation of the anterior-posterior mound as follows: "The advanced tribal chiefs of various regions of Japan, centering on the Kinai central region and Kibi, gathered together for internal and external needs, broke away from their narrow Ancestral Spirit world, that is, the regional Ritual. In addition to the above, there are many other factors that may have contributed to the development of the Japanese archipelago. [4]
The concept of the "anterior-posterior mound system" proposed by Tsuruide was a significant proposal in the study of ancient history and Archaeology, and has influenced almost all researchers in the field. The name "anterior-posterior tomb system," named by the proponent, has also been widely followed.
Sadayuki Watanabe states that in the late Yayoi period, Yayoi burial mounds were established in a unique form in each region, and ritual and political forces were formed in each region, while in the Kofun period, the size of the anterior and posterior circle mounds increased, and the protruding parts were arranged in the anterior part. [5]
In addition, Hironobu Ishino states that the anterior-posterior mound was adopted as the tomb of Okimi in the middle of the 3rd century and continued until the end of the 6th century, but the fact is that the Tsukushi Kunizukuri, who was a general of the rebellion in the Emperor Keitai In fact, the Keitai dynasty, the rebellious general Chikushi Kunizo Iwai also built tombs in the front and back, so the "front and back tomb system" was just a spirit of the chiefs, and the content of rituals actually changed greatly. [6]
Kenji Fujita disagrees with the assumption that a unified system was established "throughout the entire region" from the beginning of the 350 years of construction of giant anterior-posterior mounds. I think it is a good indicator that by the middle of the Kofun period, a power structure was in place with large anterior-anterior-cylindrical tombs being built in various parts of the country, and that the relationship between the central Kinki chiefs and local chiefs would have been at best an alliance. This is one indicator. [7]
On the other hand, it has been pointed out that the existence of the "anterior-posterior mound system" cannot be confirmed based on nationwide statistical data on the shape and size of the emperor's mausoleum, the number and distribution of its bases, the historical transition of its construction, and the location of the ancestral and oldest types.

The Kofun period is an era in the history of Japan from about 300 to 538 AD, following the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical sources tends to be distorted. The word kofun is Japanese for the type of burial mound dating from this era.
The Yamato period is the period of Japanese history when the Imperial court ruled from modern-day Nara Prefecture, then known as Yamato Province.
The Hayato (隼人), which is Japanese for "falcon-people", were a people of ancient Japan who lived in the Satsuma and Ōsumi regions of southern Kyushu during the Nara period. They frequently resisted Yamato rule. After their subjugation they became subjects of the government under Ritsuryō, and the Ministry of the Military had an office known as the Hayato-shi (隼人司) in charge of their governance. The name also came into use by samurai as a title, Hayato no suke (隼人助). In modern times, Hayato is a Japanese male given name.

Fukiishi were a means of covering burial chambers and burial mounds during the kofun period of Japan. Stones collected from riverbeds were affixed to the slopes of raised kofun and other burial chambers. They are considered to have descended from forms used in Yayoi-period tumuli. They are common in the early and mid-Kofun periods, but most late Kofun-period tumuli do not have them.

The Yamato Kingship was a tribal alliance centered on the Yamato region from the 4th century to the 7th century, and ruled over the alliance of noble families in the central and western parts of the Japanese archipelago. The age is from the 3rd to the 7th century, later than the Yamatai Kingdom. After the Taika Reform, the ōkimi as an emperor, at that time, was in power, and the Yamato period ended. The time period is archaeologically known as the Kofun period. Regarding its establishment, due to the relationship between Yamatai and Yamato's succession to the king's power, there are very different views on it.
The Hashihaka kofun is a megalithic tomb (kofun) located in Sakurai, Nara Prefecture, Japan. The Hashihaka kofun is considered to be the first large keyhole-shaped kofun constructed in Japan and is associated with the emergence of the Yamato Kingship.
The Yamatai Honshu Theory is the theory that the Yamatai kingdom was located in Honshu, specifically Kinai, where the capital was located in the Kofun period rather than in Kyushu as the Yamatai Kyushu Theory proposes.

Wakoku(和国) was the name used by early imperial China and its neighbouring states to refer to the nation usually identified as Japan. There are various theories regarding the extent of power of the early kings of Japan. According to the Book of Sui and the History of the Northern Dynasties, its borders were five months from east to west and three months from north to south. The Wajin appear in historical documents such as the Book of Han and the Geographical Survey of Japan from around the 2nd century BC. In the late 7th century, the Yamato kingdom, which had been called Yamato, changed its external name to Japan, but its relation to Japan since Book of the Later Han is not clear. There are discrepancies in the descriptions of the Old Book of Tang and the New Book of Tang.

Zenpokoenfun is an architectural model of Japanese ancient tombs (Kofun), which consists of a square front part (前方部) and a circular back part (後円部). The part connecting the two is called the middle part (くびれ部), which looks like a keyhole when viewed from above. Therefore, they are also called keyhole-shaped mounds in English, and in Korean, they are called long drum tombs (장고분) due to their resemblance to Janggu, and it is also a form of the Kofun that appeared earlier in the Kofun period along with the enpun. Generally, large Kofun are front and rear circular tombs, widely distributed in Honshu, Shikoku, and Kyushu with Gokishichidō as the center. Among them, the largest front and rear circular tomb in Japan are the Mozu Tombs with a total length of 525 meters. In addition to Japan, there are also the front and rear circular tombs in South Korea, as well as the front and rear circular tombs in Chosan County Ancient Tomb Group and Chasong County Ancient Tomb Group located in North Korea. In addition, Korean archaeologist Jiang Renqiu believes that the Songhe Dong No. 1 Tomb located in Goseong County, South Gyeongsang Ancient Tomb Group, is the Zenpokoenfun.
