Zenemonyama Kofun is a square mounded tomb constructed next to the moat of Itasuke Kofun [18]. Given its position, this tomb is considered to be related to Itasuke Kofun as a satellite tomb.
The mound length has been reconstructed to be 28 m.
On the terrace paved with pebbles, many cylindrical haniwa were arranged at wide intervals.
The construction period dates to the first half of the 5th century.
