A Study on the Change and Structure of Mahan interaction Network in Northern Kyush: Focusing on the Mahan pottery From the late Yayoi period to the early Kofun period

Records implying the interaction between the Korean Peninsula and the Japanese archipelago are found in works such as the 『漢書地理志』 and the 『魏志倭人伝』. In addition, considering that the Nakrang (樂浪)·Daebang (帶方) route was inevitably through the Mahan region, it can be seen that Mahan was also located within the Korea-Japan interaction network. This is evidenced by the large number of Mahan pottery found in northern Kyushu, where various Korean Peninsula-type pottery are concentrated. This article attempts to estimate the location and operational strategy of the Mahan interaction network from a comparative perspective, paying attention to the specificity of the logistics environment in northern Kyushu. The temporal and spatial aspects of Mahan type pottery excavated from northern Kyushu are re-examined and compared with those of the Nakrang and Byeon·jinhan(弁·辰韓) type pottery that were introduced at the same time. Through this, it can be admitted that the Mahan interaction network has been organized since the second half of the late Yayoi period, but it is judged that they have taken advantage of and participated in the network established around Nakrang in the past. Mahan's new initiative is recognized in the process of dismantling and reorganizing existing networks from the beginning to the first half of the Early Kofun Period. Furthermore, by looking at the background of the establishment and dismantling of the Nishijinmachi西新町 ruins, which are the inflection points, from a relative perspective and operational strategy, the possibility that they had a trade structure vulnerable to risk management was pointed out. Through the above results, it was possible to estimate the specific status and role of the Mahan interaction network identified in northern Kyushu. It was possible to evaluate Mahan's external capabilities in a new position during the Proto-Three Kingdom Period, which had previously received relatively little attention as part of the Samhan or as part of the Baekje. Through this, it is expected to be a study that can contribute to the reconstruction of the multifaceted and comprehensive aspects of external relations formed by Mahan while evoking research on Korea-Japan interactions during the Proto-Three Kingdom Period.
