The following is a list of Japanese military equipment of World War II which includes artillery, vehicles and vessels, and other support equipment of both the Imperial Japanese Army (IJA), and Imperial Japanese Navy (IJN) from operations conducted from start of Second Sino-Japanese War in 1937 to the end of World War II in 1945. A majority of the materials used were cotton, wool, and silk for the fabrics, wood for weapon stocks, leather for ammunition pouches, belts, etc. But by 1943 material shortages caused much of the leather to be switched to cotton straps as a substitute.
