Tumulus of Isibutai
However there are countless megalithic are left in Japan besides Tumulus of Isibutai(Stonestage).
Most of megalithic in Japan exist deep in the mountains.
Therefore the general public can't see them easily.
However there are many masonry in the cities of Europe or Middle East.
Stone statues which can't be made even by modern humans exist in the cities.
In other case the beings in the universe have made countless Crop Circles on the ground in Europe by which they try to let the info of THE UNIVERSE(THE SKY)=SORA know to humans.
Please refer to Crop Circle 481~500

Japanese people may not be able to distinguish the info of THE UNIVERSE(THE SKY)=SORA from the common channeling info, when they hear the info of THE UNIVERSE(THE SKY)=SORA is the channeling info.
Therefore it may be better to explain how the megalithic civilization was made and who made them to the people of Europe and Middle East who usually see stone civilization first.
The long and short of it, even though Japanese people may know about megalithic civilization in their knowledge, they do nothing but wonder Tumulus of Isibutai(Stonestage) in Nara is great and wonder people in ancient is great.
It is nothing but 'pearls before swine' even though we may try to inform about megalithic civilization to Japanese people.
If we consider those points, the info of THE UNIVERSE(THE SKY)=SORA may be understood by the people in foreign countries earlier than Japanese, because the people in Europe and Middle East live among megalithic which is one of the main themes of the info of THE UNIVERSE(THE SKY)=SORA.
