Japan Sea is also the residual part of Tetis Sea . Some researchers believe that it will eventually be completely swallowed by the surrounding new plates.
If the Sea of Japan is completely squeezed, the east is Japan Trench . Once the sea water retreats, this area will become the second Himalayas. At that time, global climate change will be incomparable. Now is the early stage of the formation of the second Himalayas.
has now been tightly wrapped in the mainland shelf. It is exactly the same as the Argou Island in the Western Pacific.
