Not everyone knows that in Japan there are objects with megalithic masonry, where the blocks are huge in size and weight. First question: what is it for?
The answer is in the views of the imperial palaces. Under them there is a similar, but more primitive masonry. This is a kind of wall, fortification.
The corners are laid out in the same way as in the first photo. But here, too, polygonal masonry is primitive, the blocks are poorly fitted. Degradation of technology?
Remains of the retaining wall of the palace. High quality polygonal masonry.

But most striking is the wall next to Osaka Castle. This is clearly the pouring of huge curved megalithic blocks. The layers in the monolith speak about it.
Bigger shot.
The upper blocks are different in color, probably cut and installed later.
If it is not cast, then why cut, process and move such a huge block, when you can transport it in parts and add the same volume?
Pay attention to the lower right corner - here the overlying rock did not completely hide the inner rubble stone or the lower masonry.
Is it also cast from geo-concrete?
