The earliest written records about Japanese people are from Chinese sources. These sources spoke about the
Wa people, the direct ancestors of the Yamato and other Japonic agriculturalists. Early Chinese historians described the land of Wa as a land of hundreds of scattered tribal communities. Third-century Chinese sources reported that the Wa 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. The Wa of Na also received a golden seal from the
Emperor Guangwu of the
Eastern Han dynasty. This event was recorded in the
Book of the Later Han compiled by the Chinese historian
Fan Ye in the 5th century AD. The seal itself was discovered in northern Kyūshū in the 18th century. Whitman (2012) argues that the Yayoi agriculturalists were ethnically distinct from proto-Koreans and were present in the Korean peninsula during the
Mumun pottery period. According to him, proto-Japonic languages arrived in the Korean peninsula around 1500 BC and was introduced to the Japanese archipelago by the Yayoi agriculturalists at around 950 BC, during the late Jōmon period. Koreanic languages arrived later from Manchuria to the Korean peninsula at around 300 BC and coexisted 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. Overall, the most well-regarded theory is that present-day Japanese primarily descend from the
Yayoi people and arguably, continental East Asian migrants from the
Kofun period, and to a lesser extent, the pre-existing heterogenous
Jōmon population in the Japanese archipelago.
Genetics Overall, the Yamato Japanese are related to other modern East Asians with Koreans being their closest relatives. They are also related to Northern Han Chinese populations and are genetically intermediate between the continental clusters and the indigenous Ryukyuan/Jōmon clusters. One study models the Yamato Japanese as a mixture of Korean-related and Jōmon-related ancestries and states that they are more related to Yayoi individuals with notable Jōmon affinities instead of other continental East Asian populations. In regards to Han Chinese subgroups, the Yamato Japanese are related to populations found in
Inner Mongolia, Northeastern China (e.g.
Liaoning,
Shandong etc.) and
Shaanxi. Among non-East Asians, the Yamato people show affinities with populations such as the
Dingjie Sherpa people, Northeast
Siberians and
Oceanian populations. According to a 2025 study, ancient Liaodong populations significantly contributed to the genetic makeup of Japanese after the Warring States period. == Relations with the Ryukyuans ==
