Update: 23 February 2017

Kofun (ancient burial mounds) are tombs that those in power such as emperors, empresses, baronial families and chiefs of local villages used to build from the 3rd century to the 7th century. Many ancient burial mounds are left in all over Japan particularly in Kansai region.

The History

The History

Many kofun were built in Japan from the second half of the 3rd century to the 4th century. Back then, Japan was not unified and people in power called "gozoku" (powerful family or clan) from various areas were competing one another in a power struggle. Each gozoku built a large ancient tomb to show off their authority. Later on the burying method changed from burial to cremation due to the rise of Buddism along with the change of regime, which caused the cessation of kofun in the end of 7th century.. The period from the 3rd to the 6th century when many kofun were built is named the "Kofun period" (250 AD- 538 AD), after these burial mounds.

Many ornaments were buried inside kofun. Typical ornaments were copper mirrors, arms like swords and armour and earthenware ornaments. Haniwa (terracotta clay figures) with shapes of humans and horses and cylindrical shaped earthenware were also buried together. The more grave goods there were, the more powerful the person was considered to be.
