4世纪后半叶,封土石室墓开始在日本列岛出现。日本列岛的横穴石室受到了朝鲜半岛的影响。九州地区的古坟是最早导入的。5世纪后半叶,与此不同的新型石室在近畿地方出现,并在此后的日本列岛得到了广泛普及。7世纪,由于薄葬化的推进,小型的横口式石椁墓出现,这代表着古坟文化走向了尾声。江苏连云港的封土石室墓的构造,虽与朝鲜半岛和日本列岛两地皆有类似之处,但其与中国的砖结构墓葬和朝鲜古坟的关系也是必须要考虑的。而与日本列岛石室墓的类似,笔者认为是以朝鲜半岛为中介的间接的关联。 In the second half of the fourth century, the tombstone of burial mounds began to appear in the Japanese archipelago. The Shokosa rock chamber in the Japanese archipelago has been affected by the Korean peninsula. The oldest burial mound in Kyushu was imported. In the second half of the 5th century, different new stone chambers appeared in Kinki area and were widely popularized in the Japanese islands thereafter. In the 7th century, due to the funeralization, a small horizontal cross-stony stone tomb appeared, which represented the end of the ancient tomb culture. Although the structure of the earth-burial chamber tomb in Lianyungang of Jiangsu Province is similar to that of both the Korean Peninsula and the Japanese Archipelago, its relation to the brick-structured tombs in China and the Korean burial mounds must also be considered. However, similar to the stone arch tombs in the Japanese archipelago, the author thinks it is an indirect link based on the Korean Peninsula.
