Overview
editThe Kamenokoyama Kofun is a zenpō-kōen-fun (前方後円墳), which is shaped like a keyhole, having one square end and one circular end, when viewed from above. It is located on the left bank of the lower reaches of the Tama River in the southwestern part of the Musashino Terrace in southern Tokyo within the grounds of Tamagawadai Park. Although the southern end of the posterior circular mound has been flattened due to the construction of a water purification plant, the tumulus remains well preserved. However, no archaeological excavation has been conducted.[2]
The tumulus is orientated to the northwest, and has a total length of 107.25 meters, which is the largest in the Tama River basin. The mound was built in two tiers. Neither fukiishi nor haniwa have been found. It is estimated that the tumulus was made in the middle of the Kofun period from the end of the 4th century to the early 5th century AD.[2]
