Japan 200 CE
Japan is divided into numerous warlike chiefdoms, which have close links to Korea.
What is happening in Japan in 200CE
By this stage, the Yayoi rice-farming culture covers much of southern Japan. To the north, the colder climate favours the persistence of the Jomon hunter-gathering culture, ancestral to today’s Ainu.
Contemporary Chinese texts describe Japan as being divided into many militarized chiefdoms at this time. There are strong political and cultural links between the Korean kingdoms and the Japanese chiefdoms. In particular, Korean styles in weaponry and armour exert a strong influence upon the Japanese warrior class.
