Dairizuka Kofun, Ancient burial mound in Futtsu, Japan
The Dairizuka Kofun is a burial mound with a distinctive keyhole shape that extends about 144 meters in length. The mound has a square section at one end and a circular section at the other, which was a typical design for important graves of that period.
This mound was built in the 5th century and served as a burial site for an important person in the Sue Kingdom. Its construction shows connections to the Yamato realm and was part of a larger network of burial sites from that era.
The burial contained bronze mirrors and gold-bronze fittings that show the high social rank of the person interred here. These objects help visitors today understand how important this individual was in ancient society.
The mound sits about a ten-minute walk from Aohori Station, which is served by the JR East Uchibō Line in Chiba Prefecture. The site is easy to reach on foot and can be explored without difficulty.
Excavations in 1906 uncovered a rare arrowhead made from deer bone, now displayed at the National Museum of Japanese History. This discovery shows the advanced craftsmanship and resources available for outfitting this important individual.
