Yayoi period

The Yayoi period (弥生時代, Yayoi jidai^?) is an Iron Age era in the history of Japan traditionally dated 300 BCE–300 CE, with the recently suggested revision of the beginning of transition from Jōmon period at 1,000 BCE.

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 Yayoi pottery styles and the start of an intensive rice agriculture in paddy fields. A hierarchical social class structure dates from this period. Techniques in metallurgy based on the use of bronze and iron were also introduced to Japan in this period.

The Yayoi followed the Jōmon period (14,000–1,000 BCE) and Yayoi culture flourished in a geographic area from southern Kyūshū to northern Honshū. Archaeological evidence supports the idea that during this time, an influx of farmers from the Asian continent to Japan absorbed or overwhelmed the native hunter-gatherer population.

The Yayoi period is traditionally dated from 300 BCE to 300 CE. The earliest archaeological evidence of the Yayoi is found on northern Kyūshū, but that is still debated. Yayoi culture quickly spread to the main island of Honshū, 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 900–800 BCE, 500 years earlier than previously believed.
