Tomb of Emperor Nintoku 仁徳天皇 百舌鳥耳原中陵

Three moats surround this densely forested plot of land, which is shaped like a keyhole. This is the site of Emperor Nintoku's tomb—one of the three largest tombs in the world, along with the Pyramid of Khufu in Egypt and the Mausoleum of the First Qin Emperor in China.

The tomb is accessible by train.

The inner grounds of the tomb are currently off-limits. To view the tomb from above, head to the 21st-floor observatory in the Sakai City Hall complex. From Namba Station, take the express train on the Nankai-Koya Line. Get off at Sakai-Higashi Station. Walk toward Sakai City Hall—it's the tallest building in the vicinity—and go to the 21st floor.

From ground level, the mausoleum grounds appear as a wall of forest. It's only when you catch the sight from above that the intricately designed grounds become fully apparent.

After viewing the tomb from above, walk to nearby Daisen Park. Explore the traditional garden and teahouse , and take a look inside the Sakai City Museum. The entire trip should take around two to three hours.
