Yayoi period

The Yayoi period (å¼¥ç"Ÿæ™‚代, Yayoi jidai) is an Iron Age era in the history of Japan traditionally dated 300 BC to AD 300. It is named after the neighborhood of Tokyo where archaeologists first uncovered artifacts and features from that era. Distinguishing characteristics of the Yayoi period include the appearance of new pottery styles and the start of an intensive rice agriculture in paddy fields. Techniques in metallurgy based on the use of bronze and iron were also introduced in this period. A hierarchical social class structure also emerged in this period. The Yayoi followed the Jōmon period (13,000â€"400 BC) and Yayoi culture flourished in a geographic area from southern KyÅ«shÅ« to northern HonshÅ«.

Features of Yayoi culture

The Yayoi period is traditionally dated from 300 BC to AD 300. The earliest archaeological evidence of the Yayoi is found on northern KyÅ«shÅ«, though this is still debated. Yayoi culture quickly spread to the main island of HonshÅ« mixing with native Jōmon culture. A recent study that used accelerator mass spectrometry to analyze carbonized remains on pottery and wooden stakes, suggests that they dated back to 900â€"800 BC, 500 years earlier than previously believed. Yayoi pottery was simply decorated, and produced on a potter's wheel, as opposed to Jōmon pottery, which was produced by hand. Yayoi craft specialists made bronze ceremonial bells (Dōtaku), mirrors, and weapons. By the 1st century AD, Yayoi farmers began using iron agricultural tools and weapons.

As the Yayoi population increased, the society became more stratified and complex. They wove textiles, lived in permanent farming villages, and constructed buildings with wood and stone. They also accumulated wealth through land ownership and the storage of grain. These factors promoted the development of distinct social classes. Yayoi chiefs, in some parts of Kyūshū, appear to have sponsored, and politically manipulated, trade in bronze and other prestige objects. This was possible due to the introduction of an irrigated, wet-rice culture from the Yangtze estuary in southern China via the Ryukyu Islands or Korean Peninsula. Wet-rice agriculture led to the development and growth of a sedentary, agrarian society in Japan. Local political and social developments in Japan were more important than the activities of the central authority within a stratified society.

Direct comparisons between Jōmon and Yayoi skeletons show that the two peoples are noticeably distinguishable. The Jōmon tended to be shorter, with relatively longer forearms and lower legs, more wide-set eyes, shorter and wider faces, and much more pronounced facial topography. They also have strikingly raised brow ridges, noses, and nose bridges. Yayoi people, on the other hand, averaged an inch or two taller, with close-set eyes, high and narrow faces, and flat brow ridges and noses. By the Kofun period, almost all skeletons excavated in Japan, except those of the Ainu and Okinawans, resemble those of modern day Japanese.

History

Origin of the Yayoi people

The earliest archaeological sites are Itazuke site or Nabata site in the northern part of Kyūshū. The origin of Yayoi culture has long been debated. Chinese influence was obvious in the bronze and copper weapons, dōkyō, dōtaku, as well as irrigated paddy rice cultivation. Three major symbols of the Yayoi culture are the bronze mirror, the bronze sword, and the royal seal stone.

In recent years, more archaeological and genetic evidence has been found in both eastern China and western Japan to lend credibility to this argument. Between 1996 and 1999, a team led by Satoshi Yamaguchi, a researcher at Japan's National Science Museum, 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. DNA tests conducted in 1999 support the theory that the origin of the Yayoi people was an area south of the Yangtze.

Some scholars have also concluded that Korean influence existed. Hudson has cited archaeological evidence that included but were not limited to "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.". The migrant transfusion via the Korean peninsula also gains strength due to the fact that 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.

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 mass population increase. 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.

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.

Emergence of Wa in Chinese history texts

The earliest written records about people in Japan are from Chinese sources from this period. Wa, the Japanese pronunciation of an early Chinese name for Japan, was mentioned in 57 AD; the Na state of Wa received a golden seal from the Emperor Guangwu of the Later Han Dynasty. This event was recorded in the Hou Han Shu compiled by Fan Ye in the 5th century. The seal itself was discovered in northern Kyūshū in the 18th century. Wa was also mentioned in 257 in the Wei zhi, a section of the San Guo Zhi compiled by the 3rd century scholar Chen Shou.

Early Chinese historians described Wa 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 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.

Yamataikoku

The Wei Zhi, which is part of the San Guo Zhi, 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 Kingdom of Wei. When asked about their origins by the Wei embassy, the people of Wa claimed to be descendants of the Grand Count Tàibó 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. Recent archaeological research in Makimuku suggests that Yamataikoku was located in the area. 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.
