Yamato period
A millennium earlier, the Japanese archipelago had been inhabited by the Jōmon people. In the centuries prior to the beginning of the Yamato period, elements of the Northeast Asian and Chinese civilizations had been introduced to the Japanese Archipelago in waves of migration. According to "Kojiki", the oldest record of Japan, a Korean immigrant named Amenohiboko, prince of Silla came to Japan to serve the Japanese Emperor, and he lived in Tajima Province. His descendant is believed to be Tajimamori. Archaeological evidence indicates contacts between China, Korea, and Japan since prehistory of the Neolithic period, and its continuation also at least in the Kofun period.
