日本武尊
In Yamato (Japan), the Kofun period dominated during this decade. It was an animistic culture which existed prior the introduction of Buddhism. A legend of the 4th century Prince Yamato Takeru alludes to the borders of the Yamato and battlegrounds in the area. A frontier was obviously somewhere close to the later Izumo province (the eastern part of today's Shimane Prefecture). Another frontier, in Kyūshū, was apparently somewhere north of today's Kumamoto prefecture. The legend specifically states that there was an eastern land in Honshū "whose people disobeyed the imperial court", against whom Yamato Takeru was sent to fight. That rivalling country may have been located rather close to the Yamato nucleus area itself, or relatively far away. The today Kai province is mentioned as one of the locations where prince Yamato Takeru sojourned in his said military expedition.
