The Dogu statuettes
Near the "bay of enigmatic flames", in the central Japanese island of Honshu (the largest and most important), strange dolls, known as the "Dogu Dolls", belonging to the Jomon period, were found in some caves. The dolls dated between 2500 and 1200 BC.
The peculiarity of these small gray earth statues is their rather strange "spatial" style. In fact, they present a helmet with a rectangular visor shaped and riveted around, just like modern snow goggles, or specifically cut-perforated to allow a dosed and reduced passage of sunlight; furthermore a kind of filter, placed at mouth level, probably with the aim of allowing breathing and a connection between suit and helmet consisting of a collar. The suit appears rigid, as if it had been pressurised, there are also, replacing the arms mounted on articulated heads, small manipulating pincers.
How is it possible that such advanced technological knowledge was possessed in the Neolithic?
Putting together such a composition of astronautical details seems quite difficult if you do not closely observe similar technology.
In the same area, about one hundred meters from Katsuhara's tomb, in the Kyush region, near the city of Matsubase, a strange engraving was found on one of the stones used to close a burial chamber representing a missile with delta wings and even rear flames. Can this finding be considered just a coincidence?
Perhaps this myth could be inspired by unknown and more technologically advanced races contemporary with the human population in Japan who built the statuettes as a representation of the deified entity: it could perhaps be an alien race, a visitor from space or who knows what other memory of lost technologies could influence in the artistic representation of the subject of the Dogu statuettes...
Perhaps we must also remember the myth of the "reed men" that so permeated the ancient culture of Japan and Mongolia, the legendary "Kappas". After all, these were represented not very differently by the oriental people in terms of diving suits... or we should remember the "Oannes" of the Sumerian culture or the fishmen of the Mayan culture or even the "Nommos" of the Dogon where, ultimately, it represented an amphibious race or at least one coming from the waters: who knows what these "amphibious men" were hiding under their diving suit? ...
