The East China Sea is bounded by China to the west, the Yellow Sea to the northwest, Korea and Japan
to the northeast, the Ryukyu
Islands to the southeast, and Formosa
(Taiwan) to the southwest. Because it was surrounded by Japanese bases,
the East China Sea was firmly under Japanese control until late in the
war, although American submarines penetrated the area
from the earliest days of the conflict.
