Shibuno Maruyama Kofun

Shibuno Maruyama Kofun is an ancient burial mound located in Tokushima with the characteristic keyhole shape consisting of a round section and a rectangular section connected by raised earthen walls. The structure spans several hundred meters and demonstrates the substantial scale typical of such monuments from the period.

The burial mound was built during the Kofun period between the 3rd and 6th centuries when such structures served as tombs for members of the elite. Its construction demonstrates that the Tokushima region was a center of organized power and resources at that time.

The site reflects how ancient Japanese society honored its leaders through monumental burial practices. The keyhole design itself communicates status and importance, serving as a physical statement about the person entombed within.

The site is accessible from Tokushima using public transportation and features informational signage explaining the structure and its features. Wear sturdy footwear since the terrain is uneven and pathways lead around the burial mound.

The burial mound was designated a Historic Site of Japan in 2009, highlighting its importance for understanding early regional civilization. This recognition has protected the site and enabled ongoing archaeological study of construction methods from this era.
