The Wadaoka Kofun group (和田岡古墳群, Wadaoka kofun-gun) is an archaeological site with a cluster of burial mounds from the Kofun period located in what is now part of the city of Kakegawa, Shizuoka in the Tōkai regionofJapan. The site was designated a National Historic Site of Japan in 1996.[1]
The Wadaoka Kofun group is located in an area measuring approximately 2.5 kilometers north-south by one kilometer east-west, on a low plateau overlooking the Haranoya River west of the downtown area of modern Kakegawa city. The site consists of four keyhole-shaped kofun (zenpō-kōen-fun (前方後円墳)), 15 circular-shaped kofun [ja] (empun (円墳)), and four square-shaped kofun [ja] (hōfun (方墳)), all dating from the 5th century to the sixth century AD. [2] The largest include:

These tumuli are believed to be the tombs of local kings who ruled the Haranodani River basin. The Wakanezuka Kofun is considered the oldest, but its pit-type burial chamber was robbed in 1974 before a proper archaeological excavation could be made. Many of the tumuli were once covered in fukiishi and had haniwa clay figurines, and the Yoshioka-Otsuka Kofun has traces of a moat remaining. Grave goods recovered from the tombs included, large numbers of iron weapons, fragments of armor, pottery shards and shinju-kyo bronze mirrors. [2]
The necropolis is located approximately 15 minutes on foot from the Tenryu Hamanako Line's Hosoya Station. There are plans to make an archaeological park in the area.[2]
