The term "Japanese Campaigns" typically refers to military operations conducted by the Imperial Japanese Army and Imperial Japanese Navy during various conflicts, particularly in the Second Sino-Japanese War and World War II. These campaigns aimed to expand Japan's territory and influence in Asia and the Pacific, often leading to significant battles and occupations. Key campaigns included the invasion of Manchuria in 1931, the attack on Pearl Harbor in 1941, and the subsequent battles in the Pacific Theater. These operations had profound effects on regional dynamics and contributed to the eventual defeat of Japan in 1945, reshaping the geopolitical landscape of East Asia.
