The tomb is located to the east of the Hashihaka Kofun. A road cuts through its southeast extension as can be seen in the image to the right. It is decorated with Fukiishi stones from the Makimuku river.
It has a distinctive scallop-shaped design, the burial mound measures approximately 80 meters in length. Over time, certain details of its angular contours have become less distinct due to natural wear and erosion.
Internally, the Kofun houses several burial pits and chambers. One of its noteworthy features is a reconstructed cist that contains a wooden coffin. This site has garnered attention from scholars who posit that the Hokenoyama Kofun might be among the earliest examples of the Kofun tumulus, suggesting its origin may coincide with the early Kofun period.
The 1995 excavation found a wooden coffin and a stone paved floor.t. Grave goods from the local area but also the Tōkai region and Seto Inland Sea. A mirror from it is kept in Ōmiwa Shrine.
Access to the site, though straightforward, requires navigation through a notably narrow road. However, the nearby parking facility accommodates visitors.
The area surrounding the tomb is also of archaeological significance, containing other sites such as the Hashihaka Kofun and the Makimuku Ishizuka Kofun.
