NHK Documentary - Season 15 Episode 2 The Sea of Zipangu - Deep Sea Gold Rush!
0.00 57 minutes Japan might soon experience its own gold rush! Scientists are hoping to tap the vast deposits of gold, silver, copper, and other rare metals found in oceanic plate boundaries. State-of-the-art Japanese technology is being employed to locate and extract metals from these deposits, which are produced by the dynamic forces at work inside our planet. Japan was once referred to as "Zipangu" by Marco Polo, a land fabled for its gold. With all of the new gold deposits being discovered in Japanese waters, Zipangu might not be a myth after all.
