History of JapanThe first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38-40,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD. Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization.

Sengoku periodThe Sengoku period is the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. Though the Ōnin War (1467) is generally chosen as the Sengoku period's start date, there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what is traditionally considered the Edo period.
SamuraiSamurai were the hereditary military nobility and officer caste of medieval and early-modern Japan from the late 12th century until their abolition in the late 1870s during the Meiji era. They were the well-paid retainers of the daimyo, the great feudal landholders. They had high prestige and special privileges. Following the passing of a law in 1629, samurai on official duty were required to practice daishō (wear two swords). Samurai were granted kiri-sute gomen: the right to kill anyone of a lower class in certain situations.
