古墳時代
During the Kofun period, elements of Chinese culture continued to influence culture in the Japanese archipelago, both through waves of migration and through trade, travel, and cultural change. Archaeological evidence indicates contacts between the mainland and Japan also during this period. Most scholars believe that there were massive transmissions of technology and culture from China via Korea to Japan which is evidenced by material artifacts in tombs of both states in the Proto–Three Kingdoms of Korea and Kofun period, as well as the later wave of Baekje refugees to Yamato.
