In Japanese history, the Jōmon period is the time between c. 14,000 and 300 BCE, during which Japan was inhabited by the Jōmon people, a diverse hunter-gatherer and early agriculturalist population united by a common culture, which reached a considerable degree of sedentism and cultural complexity. Their ancestors migrated from Northeast Asia, Korean Peninsula, China, and Southeast Asia. Their civilization is divided into six distinct phases. They eventually admixed with the Japonic-speaking Yayoi people.
