Jōmon period followed by Yayoi period
The Japanese chestnut, Castanea crenata, becomes essential, not only as a nut bearing tree, but also because it was extremely durable in wet conditions and became the most used timber for building houses during the Late Jōmon phase.During the Final Jōmon period, a slow shift was taking place in western Japan: steadily increasing contact with the Korean Peninsula eventually led to the establishment of Korean-type settlements in western Kyushu, beginning around 900 BC. The settlers brought with them new technologies such as wet rice farming and bronze and iron metallurgy, as well as new pottery styles similar to those of the Mumun pottery period. The settlements of these new arrivals seem to have coexisted with those of the Jōmon and Yayoi for around a thousand years.Outside Hokkaido, the Final Jōmon is succeeded by a new farming culture, the Yayoi (c. 300 BC – AD 300), named after an archaeological site near Tokyo.Within Hokkaido, the Jōmon is succeeded by the Okhotsk culture and Zoku-Jōmon (post-Jōmon) or Epi-Jōmon culture, which later replaced or merged with the Satsumon culture around the 7th century.
