The report covers industry analysis including the key market drivers, emerging technology trends, and major challenges faced by market participants. It also offers insights regarding key factors and government programs that are expected to influence the demand for military platforms over the forecast period.

The primary driver of Japan’s defense expenditure is to ensure that the country’s Self Defense Forces (JSDF) are capable of deterring military action by China, and if necessary, carrying out and sustained large scale defensive operations against the People’s Liberation Army. To that end, emphasis has been placed on training exercises aimed at strengthening inter-service interoperability, in addition to enhancing interoperability with allies including the United States, Australia, and the Philippines. The focus on a defense against China has also driven procurement programs of platforms including the Mogami-class frigate, the F-35A/B, and the Type 16 Maneuver Combat Vehicle.

Given Japan’s vulnerability to earthquakes, tsunami, and volcanic activity, the JSDF must continue to be capable of conducting nationwide humanitarian-aid disaster relief (HADR) operations.
