Yayoi period

Northern Kyushu is the part of Japan closest to the Asian mainland.

The origin of Yayoi culture and the Yayoi people has long been debated. The earliest archaeological sites are Itazuke or Nabata in the northern part of Kyūshū. Contacts between fishing communities on this coast and the southern coast of Korea date from the Jōmon period, as witnessed by the exchange of trade items such as fishhooks and obsidian.[20] During the Yayoi period, cultural features from Korea and China arrived in this area at various times over several centuries, and later spread to the south and east.[21] This was a period of mixture between immigrants and the indigenous population, and between new cultural influences and existing practices.[22]

Chinese influence was obvious in the bronze and copper weapons, dōkyō, dōtaku, as well as irrigated paddy rice cultivation. Three major symbols of Yayoi culture are the bronze mirror, the bronze sword, and the royal seal stone.

Between 1996 and 1999, a team led by Satoshi Yamaguchi, a researcher at Japan's National Museum of Nature and Science, compared Yayoi remains found in Japan's Yamaguchi and Fukuoka prefectures with those from China's coastal Jiangsu province and found many similarities between the Yayoi and the Jiangsu remains.[23][24]

Some scholars claimed that Korean influence existed. Mark J. Hudson has cited archaeological evidence that included "bounded paddy fields, new types of polished stone tools, wooden farming implements, iron tools, weaving technology, ceramic storage jars, exterior bonding of clay coils in pottery fabrication, ditched settlements, domesticated pigs, and jawbone rituals".[25] The migrant transfusion from the Korean peninsula gains strength because Yayoi culture began on the north coast of Kyūshū, where Japan is closest to Korea. Yayoi pottery, burial mounds, and food preservation were discovered to be very similar to the pottery of southern Korea.[26]

However, some scholars argue that the rapid increase of roughly four million people in Japan between the Jōmon and Yayoi periods cannot be explained by migration alone. They attribute the increase primarily to a shift from a hunter-gatherer to an agricultural diet on the islands, with the introduction of rice. It is quite likely that rice cultivation and its subsequent deification allowed for a slow and gradual population increase.[27] Regardless, there is archaeological evidence that supports the idea that there was an influx of farmers from the continent to Japan that absorbed or overwhelmed the native hunter-gatherer population.[26]

Some pieces of Yayoi pottery clearly show the influence of Jōmon ceramics. In addition, the Yayoi lived in the same type of pit or circular dwelling as that of the Jōmon. Other examples of commonality are chipped stone tools for hunting, bone tools for fishing, shells in bracelet construction, and lacquer decoration for vessels and accessories.

According to several linguists, Japonic was present on large parts of the southern Korean peninsula. These "Peninsular Japonic languages" were replaced by Koreanic-speakers (possibly belonging to the Han-branch) likely causing the Yayoi migration.[28][29] Similarly Whitman (2012) suggests that the Yayoi 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 at around 950 BC. 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.[30]

Most linguists and archaeologists agree that the Japonic language family was introduced to and spread through the archipelago during the Yayoi period.

The golden seal said to have been granted to the "King of Wo" by Emperor Guangwu of Han in 57 AD. It is inscribed King of Na of Wo in Han Dynasty (漢委奴國王)

The earliest written records about people in Japan are from Chinese sources from this period. Wo, the pronunciation of an early Chinese name for Japan, was mentioned in 57 AD; the Na state of Wo received a golden seal from the Emperor Guangwu of the Later Han dynasty. This event was recorded in the Book of the Later Han compiled by Fan Ye in the 5th century. The seal itself was discovered in northern Kyūshū in the 18th century.[31] Wo was also mentioned in 257 in the Wei zhi, a section of the Records of the Three Kingdoms compiled by the 3rd-century scholar Chen Shou.[32]

Early Chinese historians described Wo as a land of hundreds of scattered tribal communities rather than the unified land with a 700-year tradition as laid out in the 8th-century work Nihon Shoki, a partly mythical, partly historical account of Japan which dates the foundation of the country at 660 BC. Archaeological evidence also suggests that frequent conflicts between settlements or statelets broke out in the period. Many excavated settlements were moated or built at the tops of hills. Headless human skeletons[33] discovered in Yoshinogari site are regarded as typical examples of finds from the period. In the coastal area of the Inland Sea, stone arrowheads are often found among funerary objects.

Third-century Chinese sources reported that the Wa people 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. Society was characterized by violent struggles.

The Wei Zhi (Chinese: 魏志), 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.[34] When asked about their origins by the Wei embassy, the people of Wa claimed to be descendants of the Taibo of Wu, a historic figure of the Wu Kingdom around the Yangtze Delta of China.

For many years, the location of Yamataikoku and the identity of Queen Himiko have been subject of research. Two possible sites, Yoshinogari in Saga Prefecture and Makimuku in Nara Prefecture have been suggested.[35] Recent archaeological research in Makimuku suggests that Yamataikoku was located in the area.[36][37] Some scholars assume that the Hashihaka kofun in Makimuku was the tomb of Himiko. Its relation to the origin of the Yamato polity in the following Kofun period is also under debate.
