The tumuli are built on a plateau overlooking Osaka Bay near the ancient coastline and are distributed in a range of about four kilometers from east-to-west and north-to-south.The Furuichi Kofun Cluster is located in nearby Habikino and Fujiidera cities.
[5] They represent a cultural tradition which is an expression of "forms, and design of the kofun" of the sociopolitical hierarchical order and the link that was prevalent during that period between regions.
The larger ones are keyhole-shaped (zempō kōenfun); they represent the highest class of kofun and were built in great detail.
[6] A feature of these funerary mounds is that they contain – along with the buried people – grave goods made of iron, weapons worn by individuals including arrowheads, swords, hoe and spade tips, and many other similar items.
Also found in the mounds are antiquities made of gilded bronze such as horse tacks and sash buckles.
The highest point is 47 metres (154 ft), making it visible to the seafarers in nearby Osaka Bay.
Today, the tomb is off-limits and protected by the Imperial Household Agency in the centre of Sakai City.
The viewing platform is 500m away from Mozu Station on the Hanwa Line and is directly across the street from the Sakai City Museum.
