Tokugawa Foreign-Trade Ambivalence

Tokugawa foreign-trade ambivalence is the source’s pattern where the early Tokugawa Shogunate / 德川幕府 wants foreign trade, navigation knowledge, shipbuilding, and diplomatic options while also fearing Christianity and foreign political leverage. In 14.武士威廉：大航海时代的日本和西方, [[TokugawaIeyasu|Tokugawa Ieyasu]] is open enough to use [[WilliamAdams|William Adams / 三浦按针]], build ships, and discuss trade, yet concerned enough to expel Jesuits / 耶稣会 in 1614.

The concept is not simple isolationism. The episode presents restriction as a political choice made after rulers judge that missionary networks and foreign pressure can threaten rule. Adams’s career shows the upside of foreign connection; the later withdrawal of English traders and survival of a narrow Dutch channel show the downside calculus winning.

Key Claims

• Early Tokugawa policy includes genuine openness to trade and technique.
• Christian mission networks turn commercial contact into a loyalty and governance problem.
• Adams is protected because he is useful and not aligned with Jesuit missionary pressure.
• The later Sakoku Dutch Window reflects selective risk management rather than a complete absence of exchange.
