Known in English as the Tomb of Emperor Nintoku (or Daisen Kofun in Japanese), this behemoth complex is approximately 840 meters long and allegedly belongs to the 16th emperor of Japan. The massive keyhole-shaped structure is ranked as one of the world’s three largest tumulus together with the Mausoleum of the First Qin Emperor in China and the Great Pyramid of Khufu in Egypt. To put its size in perspective, the girth of Emperor Nintoku’s final resting place is about twice that of the Great Pyramid of Giza, albeit at only a quarter of the height.
Now before you get your hopes up, know that you cannot actually venture inside the Tomb of Emperor Nintoku. Sorry, Indiana Jones wannabes. You see, the Imperial Household Agency actually is in charge of overseeing the site. As such, tourists, archaeologists, and even royalty can generally only venture as far as the bridge over the second moat.
Officially, the Imperial Household Agency has stated that the Tomb of Emperor Nintoku is a consecrated site and should not be defiled by the likes of commoners. When asked to comment on why the agency is reluctant to allow even archaeologists to explore the structure, the response holds that the mound is “an Imperial Family tomb where peace and sanctity need to be maintained.” Knowing Japan as well as I do though, I call bullshit here.
Rather than being concerned about upsetting the specter of a long dead emperor, I have an inkling that the Imperial Household Agency is actually worried about unearthing imperial connections to Korea which would undermine the established narratives.
or maybe some other reason?

Nobody has been across the inner moat since a typhoon damaged the lower part of the keyhole shape in 1872. During the restoration at that time, many artifacts were uncovered. The findings provided a substantial amount of information. However, some of the artifacts were inconsistent with what was previously known about the time period, casting some doubt on the identity of the tomb’s owner.
No further activity is allowed on the island, so the mystery of the occupants may never be solved. The main part of the tomb at the top part of the keyhole has remained completely untouched for over a thousand years and will likely remain that way for many more.
