Nagayama Kofun is considered one of the satellite mounds of Daisen Kofun. Whether this was an individual grave site or a site for servants or retainers is unknown.

The farm was closed in 2011 after a long, and somewhat odd, legal battle with the city of Sakai. Click on the image for a larger view.
