Mozu Kofun Group

Emperor Nintoku Kofun (Daisen Kofun), Sakai Keyhole-shaped burial mounds surrounded by moats are the great monuments of Japan's early rulers, and the largest here, believed to be the tomb of Emperor Nintoku, is about 800 meters long and 600 meters wide including its moats. The catch is that the tombs are generally closed to the public and look like wooded hills from the ground. Go up to the free observation deck on the 21st floor of Sakai City Hall, about a kilometer away, to grasp the shape, then walk around Daisen Park. The group joined the World Heritage list in 2019. From Tennoji, take a JR Hanwa Line rapid train to Sakaishi, then a local train to Mozu Station, about 11 minutes of riding in all.
