From the statement, 'The capital of Yamatai Kingdom is in Yamadai Kingdom according to Gishi-wajin-den (the first written record of Japan's commerce)' in Suishu (the Book of the Sui Dynasty), it would appear that the Yamatai Kingdom existed until the seventh century.
『隋書』に「邪靡堆則魏志所謂邪馬臺者也」とあり、邪馬臺国は7世紀まで存続していたと考えられる。
