Bōnotsuka Kofun, Ancient burial mound in Japan
Bōnotsuka Kofun is a burial mound with a distinctive keyhole shape, where a square front section connects to a circular rear portion. The entire structure was built by mounding earth and now stands as a physical reminder of ancient Japanese burial practices.
This burial mound dates to between the 3rd and 7th centuries, when such structures were built for wealthy and influential members of society. During this period, these monuments reflected the political power and prosperity of Japanese regions.
These burial mounds served as gathering places where communities came together to honor their deceased leaders. The shape and size reflected the rank and importance of the person entombed within.
The site is protected by regulations that limit excavation to preserve the original structure. Visitors can view the exterior of the mound but should remain respectful and avoid climbing on the monument itself.
The keyhole shape is especially striking when viewed from above and was likely chosen deliberately to create impressive visual effects during ceremonial occasions. This particular form distinguished these mounds from simple earth piles and made them recognizable symbols.
