From the very beginning, Japanese military aviation was split under the direct command of the two main services, the Army and the Navy, creating their own strategies and becoming hard competitors in the process. It remained as such practically until the end of the Pacific War. Not surprisingly, the Japanese Naval Air Force was influenced by Great Britain, while the Japanese Army Air Force looked upon the major land powers of the time: France, Russia and Germany.
