This 130-meter-long keyhole-shaped tumulus, built in the late 3rd century, is particularly famous for the large number of 33 triangular-rimmed mirrors bearing divine beasts that were excavated from it. It has been developed into a park, and there are information boards and stairs leading up to the tumulus.
As mentioned above, a large number of triangular-rimmed mirrors bearing divine beasts have been excavated from this tumulus. These mirrors are thought to have been given to Himiko by the Wei Dynasty, so I think this tumulus supports the theory that Yamataikoku was located in the Kinai region.
Visited in March 2026.
It's about a 10-minute walk from Yanagimoto Station.
It's easy to visit, and you can even climb on top of the burial mound. The nearby exhibition hall apparently has free admission, and I wanted to visit it, but it was closed, so I gave up.
This keyhole-shaped tumulus is approximately 130 meters long. It is beautifully maintained and includes an exhibition hall and a park. There is a free municipal parking lot behind the Family Mart along the national highway, and you can walk there from there.
It's a nationally designated historic site and is a magnificent burial mound surrounded by a moat.
It's also tall.
The nearest station is Yanagimoto Station, which is just over a five-minute walk away.
