Enter the stone burial chamber built with massive stones and experience the scale of ancient civil engineering

About this spot

One of Japan's largest square tumuli, built in the early 7th century, with a strong theory that it is the grave of Soga no Umako, who wielded great power. The name derives from its appearance of a huge stone chamber exposed after the earthen mound was lost. Approximately 30 granite blocks total about 2300 tons in weight, with the ceiling stone alone weighing roughly 77 tons. The greatest attraction is being able to actually enter the stone chamber; standing inside the cool space and looking up at the massive stones overhead sparks parents and children's imaginations about how these could have been stacked in an era without cranes. The surrounding area is maintained as the Ishibutai district of the National Asuka Historical Park, perfect for a brief rest on the lawn. In spring there are cherry blossoms, and in autumn spider lilies—surrounded by scenery typical of Asuka's rural hills, this is the highlight of the course.

Tips

By rental bicycle, it's about 15 minutes from Asuka-dera Temple through terraced rice fields. Paid parking and bicycle parking are available. The stone chamber floor is earth and some areas are dimly lit, so hold children's hands and watch your footing. You can buy snacks at the shop in the surrounding lawn area and take a break. Morning arrival before the ticket booth gets crowded with school excursions and tour groups is more comfortable.
