Forced opening, silver trade, and Japan's American threat memory

Japan's insecurity had a regional resource dimension: access to raw materials was hemmed in by American, British, Dutch, French, Russian, and Chinese imperial systems. Britain could still be remembered as Japan's former protector, while the United States became the traditional coercive threat after the forced opening commonly associated with Commodore Perry. That opening became a national-scale psychological shock. Commercial powers wanted access to Japanese markets and silver because silver underpinned trade with China and much of the wider global economy. Japan's proximity to China made its bullion especially attractive compared with transporting silver from Europe or the Americas. This background helps explain why early Japanese planners treated aviation and other naval capabilities as offsets against stronger imperial powers rather than as isolated technologies.
