The Structure and Changes of Gaya–Wa Exchange Based on Tomb Evidence

Archaeological evidence from Gaya tumuli reveals that exchanges between Gaya and Wa (倭) in the Japanese archipelago were not merely one-way cultural borrowing but involved sustained, two-way interactions. The study identifies structural affinities in burial construction techniques, such as earthen embankment methods, linking Gaya's large mounds to keyhole-shaped mounds in western Japan. This suggests human mobility and technological exchange, particularly centered around Geumgwan Gaya from the mid-fourth century. Additionally, Wa-style stone-chamber tombs concentrated in southern Gaya after the sixth century indicate local adaptation alongside continuity with Kyushu traditions, reflecting strategic political objectives and maritime significance during periods of increased pressure from neighboring Korean states.
