Skin diving off Kamiyama Island.

Science fiction writer Arthur C. Clarke was so fascinated with space that he began diving and found the universe in the feeling of weightlessness.

The undersea is not only the origin of humanity and life, but also an unknown planet completely unknown to man.
We humans still know only 5% of the deep-sea world.

Exploring the possibility of extraterrestrial life in space is exciting, but summarizing the origins of humanity in the deep sea is also romantic.

This is how the “deep-sea floor megascape” looks like.
