The term "Japanese invasion" often refers to Japan's military expansion during the early 20th century, particularly in Asia. This period included the invasion of Manchuria in 1931 and the subsequent attacks on China and other territories during World War II. Japan aimed to establish a greater empire and secure resources. The invasion led to significant conflicts, including the brutal Second Sino-Japanese War and the occupation of various countries in the Pacific. The actions of the Japanese military resulted in widespread suffering and resistance from local populations, ultimately contributing to Japan's defeat in 1945 and the end of its imperial ambitions.
