Overview

The Aotsuka Kofun is located in the southern part of Inuyama, in western Aichi Prefecture. It is one of tumuli which once formed a kofun cluster in the surrounding area (most of which have now been destroyed). Archaeological excavations have been conducted in 1979 and from 1995 to 1998. [2]

The tumulus 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 has a total length of 123 meters and is orientated to face southwest. It consists of a three-tiered posterior circular portion with a diameter of 78 meters and height of 12 meters, and a two-tier trapezoidal anterior portion, with a width of 62 meters, length of 45 meters and height of seven meters. A surviving portion of a moat is on the west side of the tumulus, and on the east side a raised embankment for crossing the now vanished portion of the eastern moat has also survived. An unusual feature of this kofun is the presence of a rectangular mound on the far end of its anterior portion, which may have been a ceremonial platform. The tumulus was formerly covered in fukiishi across its entire surface, and had rows of cylindrical and drum-shaped haniwa. It is believed to have been built in the middle of the 4th century in the early Kofun period. [2]

The kofun is associated with the Ni-no-miya of Owari Province, Ōagata Shrine, which is located 3.5 kilometers to the east. The shrine claims that the kofun is the grave of its kami, Oarata-no-mikoto (大荒田命). During the Sengoku period, the tumulus was fortified as a castle by the forces of Toyotomi Hideyoshi during the 1584 Battle of Komaki and Nagakute.[2]

The site is now open to the public with the exterior of the tumulus restored to its appearance at the time of construction, with a row of replica pot-shaped haniwa as part of the Aozuka Kofun Historical Park , which also has an on-site museum. It is located about a 30-minute walk from Gakuden Station on the Meitetsu Komaki Line.[2]
