List of Japanese military equipment of World War II

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.^[1]

The Empire of Japan forces conducted operations over a variety of geographical areas and climates from the frozen North of China bordering Russia during the Battle of Khalkin Gol (Nomonhan) to the tropical jungles of Indonesia. Japanese military equipment was researched and developed along two separate procurement processes, one for the IJA and one for the IJN. Until 1943, the IJN usually received a greater budget allocation, which allowed for the enormous Yamato-class battleships, advanced aircraft such as the Mitsubishi A6M "Zero" series, and the world's largest submarines. In addition, a higher priority of steel and raw materials was allocated to the IJN for warship construction and airplane construction. It changed to a degree in 1944/45, when the Japanese home islands became increasingly under direct threat, but it was too late. Therefore, during the prior years the Imperial Japanese Army suffered by having a lower budget allocation and being given a lower priority as to raw materials, which eventually affected its use of equipment and tactics in engagements during World War II.

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.
