Kofun system

The ja is a social order seen in the construction of stylized Kofuns 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. 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. 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.
