How did Japan's military history shape cultural exchange?

Japan's long military history, from the emergence of the samurai and the unification of kingdoms to its transformation into a major imperial power, has deeply intersected with cultural developments. Military conflicts and shifts in governance continually altered Japan's domestic society and its interactions with neighboring Asian nations and Western powers. Across centuries of feudal rule, civil wars, and modernization, military institutions played a central role in shaping the nation's trajectory, while cultural practices like music were shared across borders.
