In this article, I will talk about a granite sarcophagus, the processing of which is amazing, even by modern standards. I have seen many megaliths, in different parts of the planet, but only a few of them have been treated this way.
In Asuka Park, in Japan, there are many megaliths and one of the most interesting is a granite sarcophagus, looking at which it becomes immediately obvious that it is impossible to do this by hand.
Take a look at this precision, how everything is perfectly done and polished. Someone can seriously say that something like this can be created with primitive tools? In this case, it is machine processing, or technologies of the past unknown to us.
And based on a recent article on the sarcophagi of Egypt, it becomes clear that then there were no problems with the processing and polishing of granite.

As for this sarcophagus, and other megaliths in the park, they officially date back to the 7th century AD. However, many independent experts, for unknown reasons, are sure that they created them much earlier.
In principle, this object, it seems to me, is the most interesting, but we can also say about a variety of megaliths, with strange processing, depressions and "stairs" in the stones. This is no longer a rarity for civilizations of the past, but the park also has it.

In general, there is no longer such an ideal processing of granite, but there are megaliths weighing 50 tons or more, and some of them have right angles, and the stones themselves seem to be carved in those places.
By the way, it is worth noting that the part with the same tomb is now closed for tourists. One can only guess what the access was closed for, but there are already pictures.
Probably, looking at the photo, many will say that the stone has cracked, but the version is, to put it mildly, questionable.
It can be concluded once again that a thousand years ago, for civilization (or civilizations) there were no special problems to polish and process granite ideally according to the most accurate calculations. This sarcophagus once again confirms this, although such finds are not so few.
