Gyōda Futagoyama Kofun

Gyōda Futagoyama Kofun is a keyhole-shaped burial mound in the city of Gyoda measuring approximately 132 meters long. The mound features a circular rear section and a rectangular front area, with a double moat system running around the entire structure.

This burial mound dates to the 6th century and received Special National Historic Site status in 2020. It is the largest tumulus in the historical Musashi Province and part of a larger cluster of burial structures in the region.

The site's name reflects its regional importance as a sacred burial place for someone of high status. Walking around the mound, you can sense how much effort the community invested in honoring this person through the monumental scale and careful design.

The site is freely accessible and you can walk around the mound to view it from different angles. Good walking shoes are recommended since the ground can be uneven as you explore the exterior and the surrounding moat areas.

Researchers discovered a hidden stone chamber in the eastern section of the circular portion using ground-penetrating radar without any excavation. This finding shows how modern technology helps explore ancient structures while keeping the mound intact.
