Japan’s defence expansion cannot be assessed merely by the size of its procurement budget. The real measure of progress lies in the Domestic Content Ratio (DCR) — the share of a programme’s total value that is generated within Japan through domestic design, production, subcontracting, and maintenance.
This metric reveals whether rising budgets are translating into actual industrial capacity, skilled employment, technological autonomy, and export potential. A growing DCR indicates that spending is strengthening national production bases, reducing schedule and supply risks, and stimulating innovation. A stagnant ratio, by contrast, signals structural dependence on imports and U.S.
