U.S. naval expedition commanded by Matthew Perry forced Tokugawa shogunate to sign Treaty of Kanagawa ending two centuries of isolationist sakoku policy and opening ports to American commerce. This coercive diplomatic achievement integrated Japan into global capitalist networks, triggering internal crises that led to Meiji Restoration. Forced opening demonstrated how military power enforced economic integration in nineteenth-century imperialism.

Meiji-era poets grappled with sudden exposure to Western goods, ideas, and literary forms, creating hybrid genres blending classical waka with translated European models. Yosano Akiko's tanka collections expressed female desire and economic independence impossible under feudal constraints. The trauma of forced modernization generated nostalgic traditionalism alongside enthusiastic adoption of foreign poetic techniques.
