Gaint megalithic structures found underwater off a remote island in Japan. Some argue it’s man-made, while others say it’s a unique natural site. Lots of 90 degree angles, big steps, supposed carvings, obvious shapes, hieroglyphics, and an underwater cave with stalagtites (which can only form on dry land). There’s also a huge carving of what looks like a face. On the island, there’s a similar face with a big tongue the locals think is an alien face. The locals consider it a sacred place and from the top there’s evidence of possible rituals performed there and an immense view of that side of the island. Also nearby is a granite structure called the “rock spaceship” that’s supposed to be a granite rock carved into a tomb that was abandoned before complete. However, it looks nothing like tombs in Japan.
