大堤權現塚古墳

The Otsutsumi Gongen-zuka Kofun is a circular earthen mound located in Chiba Prefecture that contains a stone burial chamber inside. The structure dates to Japan's middle Kofun period and displays the characteristic architecture of that era, with an underground chamber accessible through a passage.

The mound was constructed in the 5th century to serve as a burial place for influential regional leaders in the Chiba area. This period represented a shift toward more complex burial chamber designs and increased investment in monumental architecture.

The site reflects how ancient communities valued their leaders and invested effort in elaborate burial practices to honor the dead. Visitors can sense the importance placed on craftsmanship through the metal tools and ornaments that were placed inside the chamber.

The mound sits in a rural area and remains open for visitors interested in exploring ancient Japanese archaeology. Come during dry weather when the ground is easier to walk on, as the area can become muddy after rain.

Access to the inner stone chamber was gained through a narrow passage that may have been sealed after the burial was complete. This practice was common among tombs of the era to protect the burial site and restrict entry.
