the Later Han compiled by Fan Ye in the 5th century. The seal itself was discovered in northern Kyūshū in the 18th century. Early Chinese historians described Wa as a land of hundreds of scattered tribal communities. Third-century Chinese sources reported that the Wa/early Yamato lived on raw fish, vegetables, and rice served on bamboo and wooden trays, clapped their hands in worship (something still done in Shinto shrines today), and built earthen-grave mounds. They also maintained vassal-master relations, collected taxes, had provincial granaries and markets, and observed mourning. The Wei Zhi (), which is part of the Records of the three Kingdoms, first mentions Yamataikoku and Queen Himiko in the 3rd century. According to the record, Himiko assumed the throne of Wa, as a spiritual leader, after a major civil war. Her younger brother was in charge of the affairs of state, including diplomatic relations with the Chinese court of the Kingdom of Wei. When asked about their origins by the Wei embassy, the people of Wa claimed to be descendants of the people of Wu, a historic figure of the Wu Kingdom around the Yangtze Delta of China, however this is disputed. Japonic speakers were also present on the southern and central "Korean Peninsula". These "Peninsular Japonic agriculturalists" were later replaced/assimilated by Koreanic-speakers (from southern Manchuria) likely causing the Yayoi migration and expansion within the Japanese archipelago. Whitman (2012) suggests that the Yayoi agriculturalists are not related to the proto-Koreans but that they were present on the Korean peninsula during the Mumun pottery period. According to him, Japonic arrived in the Korean peninsula around 1500 BC and was brought to the Japanese archipelago by the Yayoi agriculturalists at around 950 BC, during the late Jōmon period. The language family associated with both Mumun and Yayoi culture is Japonic. Koreanic arrived later from Manchuria to the Korean peninsula at around 300 BC and coexist with the descendants of the Japonic Mumun cultivators (or assimilated them). Both had influence on each other and a later founder effect diminished the internal variety of both language families. A genetic study (2019) estimated that modern Japanese (Yamato) share more than 90% of their genome with the Yayoi rice agriculturalists and less than 10% with the heterogeneous Jōmon period groups. A more recent study by Gakuhari et al. 2019 estimates that modern Japanese people have between 92% to 96,7% Yayoi rice-agriculturalist ancestry (with the
