The term "Japanese Wars" refers to various conflicts involving Japan throughout its history, including the Sengoku period, the Russo-Japanese War, and World War II. These wars often shaped Japan's political landscape, territorial boundaries, and military strategies. The Sengoku period (1467-1603) was marked by internal strife among feudal lords, while the Russo-Japanese War (1904-1905) showcased Japan's emergence as a global power. World War II (1939-1945) was a significant conflict for Japan, leading to its involvement in the Pacific Theater and ultimately resulting in its defeat. The aftermath of the war brought about major changes, including the adoption of a pacifist constitution and the rebuilding of Japan's economy.
