Abstract

Based on the results of the excavation of the Janggobong Ancient Tomb in Bangsan-ri, Haenam, this paper reviewed the structural characteristics of the stone chamber and examined the background and meaning of the emergence of the Janggobong Ancient Tombs. The Janggobong Ancient Tomb is identified as the “open coffin” in the Kyushu region of Japan and multiple chamber structures and are understood as “the creative type” built by the material limitations of construction stone and indigenous construction methods (sealed soil). Considering that it is structurally similar to the stone chamber of the Janggobong Ancient Tomb, it is identified as the Saba-Mitoyo-type stone chamber in the Setouchi coastal area of Japan. Among them, the stone chamber in the front part of the Kurumazuka Ancient Tomb is very similar to that of the Janggobong Ancient Tomb in the size and planar form, the wall stone construction method, the shape of the ceiling stone, the ceiling height of the tomb room and the front room, and the shape of the door pillars at the main gate. The Janggobong Ancient Tomb and the Saba-Mitoyo-type Stone Chamber correspond to the “creative” stone chamber combined with indigenous characteristics under the influence of Kyushu-type stone chamber. The emergence of the “creative” stone chamber has the background of interaction between Baekje and Japan after the 5th century, when a new relationship was established and routes were pioneered. In this exchange and negotiation interaction, the forces represented by the Janggobong Ancient Tomb in Haenam and the Saba and Mitoyo regions of the Setouchi Sea in Japan actively used geopolitical points corresponding to the path of coastal routes to promote growth from an intermediary's point of view, and as a result, it is presumed that the “creative” stone chamber was created.
