Japanese OOPArts

Out-of-place artifact (OOPArt) is a term coined by American naturalist and cryptozoologist Ivan T. Sanderson for an object of historical, archaeological, or paleontological interest found in a very unusual or seemingly impossible context that could challenge conventional historical chronology by being "too advanced" for the level of civilization that existed at the time, or showing "human presence" far before humans were supposed to exist.


The ley line

Ley lines are supposed alignments of a number of places of geographical and historical interest, such as ancient monuments and megaliths, natural ridge-tops and water-fords.

Some ancient ruins are built so that they form a line. People couldn't have a ability to build them in a line.

This one is really correct and weird. The center blue line traces the three imperial capital, 飛鳥京(?), 平城京(710), and 平安京(794). 5 exteriors are mainly shrines.

The floating stone (天の浮石)

This looks as if it floated, in fact there is thin support in the water. It's unknown when, who, and why made it. Now it's enshrined as God's body. Some people think this is similar to nowadays houses.

The Dutchman doctor, Siebold, visit Japan in 1823, illustrated this stone.

Utsuro bune (The imaginary ship in a literal translation)

"Utsuro bune is made from iron, has windows, and is written some sentences. The foreign woman rode in the ship."

Was it a UFO? People called it Utsuro bune or Sorafune(Airship).

The Japanese pyramid (Mt. Ashitake)

I can't believe it was made by nature. There are signs that stones are piled up. There are more pyramid-like mountains in Japan.

The will of TOKYO SKYTREE

It was drawn in 1800s, but there is the weird tower. It's roughly the same place as TOKYO SKYTREE. It is said to be a turret, but isn't it too high?
