Kofun period

Kofun period

Around the middle of the 3rd century A.D., when Himiko, a female ruler of the early Japanese political federation known as Yamatai, is said to have died, monumental keyhole-shaped tumuli (zenpō-kōen-fun) began to be built across the Japanese archipelago, thus opening an era in Japan’s history now known as the Kofun period.

The Kofun period dates from the middle of the 3rd century to the 7th century, and is characterized by the formation of the Japanese state. The number of kofun built thoughout the archipelago during this period reached a total of roughly 80,000.

Let us learn what the numerous discoveries at Nonaka Kofun tell us of this tumultuous age.
