What did the Japanese accomplish in the Second Sino-Japanese War?

Answer 1

Much of China's coast was occupied, and the KMT nationalists were unable/unwilling to stop them so had to retreat further inland. This puts vast amounts of China's resources in and the majority of the railroad system in Japanese hands.

Answer 2

During the Second Sino-Japanese War, which lasted from 1937 to 1945, the Japanese Empire was able to seize control of large parts of China, including major cities such as Shanghai, Nanjing, and Beijing. However, they faced fierce resistance from Chinese forces and ultimately failed in their goal of fully conquering and subjugating China. The war had devastating consequences for both sides, resulting in millions of deaths and widespread destruction.
