The age-old struggle of the Japanese against the northern barbarians, the Ainu, on the islands of Honshu and Hokkaido resembles the “onslaught to the East” (Drang nach Osten) of German feudal lords in the XII-XV centuries. In this expansion, the Japanese “outstripped” the Germans by two centuries. The fierce rivalry between the Taira and Minamoto clans for the right to unite Japan in the 12th century is reminiscent of the war of the Scarlet and White Rose in 15th century England and the strife between the kings of France and the dukes of Burgundy at the end of the Hundred Years War and immediately after it. Here, too, Japanese history “outstripped” the European rhythm of social development.
