Archaeologists believe they have identified the tomb of the legendary Queen Himiko, who ruled the Yamatai kingdom in the 3rd century.
One of the biggest question marks remains over whether Himiko was a queen or more of a shaman.
Excavation of the tomb could settle that debate once and for all, although the Imperial Household Agency appear to have ruled that out.
“I would love to be able to excavate the tomb, but it is impossible to get permission because the agency says that our present emperor is descended from Queen Himiko,” said Professor Harunari. “But I still believe the evidence fits and this is her tomb.”
