The correct answer is - South China Sea.
Japan is an island nation, surrounded by water bodies on all sides, but the South China Sea is not one of them.
The water bodies that surround and touch Japan are the Philippine Sea, Sea of Japan, Pacific Ocean, East China Sea, and Sea of Okhotsk, with a couple of straits also involved in the picture.
The South China Sea, on the other hand, is a sea that is located between the islands of Southeast Asia and the southern part of China, going eastwards to Taiwan, but is not reaching the shores of Japan.
