Daisen-Kofun (5th century)
The tomb of Emperor Nintoku, Sakai, Osaka Prefecture, Japan,
Emperor Nintoku, also known as Ohosazaki no Sumeramikoto was the 16th Emperor of Japan, according to the traditional order of succession.
The most prevalent and recognizable shape among kofuns is the keyhole design. This design resembles, quite literally, a keyhole when viewed from above. The keyhole-shaped kofuns consist of a circular or rectangular portion at one end and a long, narrow, and elevated section that tapers towards the other end.
These kofuns are known as the “zenpo koen fun.” The square part of the keyhole shape (zenpo-bu) serves as the head section. In contrast, the entombed person occupies the round part (koen-bu).
The hori (or moat) is an evacuated area of earth used to make the mound forming a moat.
The grandeur and size of keyhole-shaped kofuns can be awe-inspiring. Among them, we find some truly colossal examples, such as the renowned Daisen Kofun in Osaka, extending over 400 meters (1,300 feet).
These colossal monuments stand as testaments to the power and prestige of the individuals they were built to honor.
