The artifact is correctly called Masuda-no-Iwafune, but for ease of understanding and writing, we will simply call it Masuda.
Masuda is located in the middle of a bamboo forest, weighs about 800 tons, and its purpose remains a big mystery to everyone.
As is customary for most mysterious ancient artifacts, no written evidence of its creation or mention has been found.
As a result, we have a mysterious object in the middle of the forest with a completely incomprehensible purpose for us.
On the upper side, rectangular holes have been made in the megalith, but for what purpose? Do not forget that the artifact is made of granite, and it was very difficult to process it in ancient times. In other words, each hole must have a specific purpose.
Now the holes are filled with water, but what could they have been intended for 5 or more thousand years ago?

Masuda hides the secrets of his creation from his other side. The back of the artifact has a mysterious mesh structure.
But that's not all the oddities of this object. According to researchers from LAI, there are no chipping marks from primitive tools on the treated surface of the artifact. But how was it processed then?
So many mysteries are usually characteristic of objects created by an ancient highly developed civilization, about which we know almost nothing.
Masuda may be no exception. However, this cannot be assured with certainty either. At the moment, Masuda remains a mysterious and unexplained artifact in Japan.
