Located near the roadside station called Misaki Yume to-dai, The Nishi-Koyama kofun looks like an ordinary hill, but here is a special place because the gold-plated helmet was unearthed when excavations were conducted before WWⅡ. After that, the helmet was on display at donjon of Osaka castle. However, it disappeared from there in 1955, when the postwar confusion still lingered and is still missing now.
This kofun is said to have been made in the middle of the 5th century and is believed to be the tomb of Ki clan, Load that ruled here at that time. How about thinking about the romance of prehistoric times while walking on top of the tomb?
