長尾山古墳

Nagaoyama Kofun is an ancient burial mound shaped like a keyhole, with a rectangular section on one end and a circular section on the other. The entire structure stretches about 190 meters (620 feet) in length and shows the advanced construction methods of that era.

This burial mound was built around 1,600 years ago during a time when such monumental structures honored important people. That period was crucial for developing Japanese tomb architecture and burial practices.

The site reflects how ancient communities remembered their dead and valued certain objects for the afterlife. The pottery and decorative items found here show what mattered to people in that era.

This site is accessible to visitors, though it sits within a residential area so respect for local residents is important. The best views of the structure come from elevated spots, which helps when exploring the layout.

The surface is covered with white fukiishi stones that kept their pale color across centuries. Excavations uncovered both cylindrical and figurative haniwa clay objects that held religious and cultural meaning for ancient people.
