William Adams / 三浦按针

William Adams / 三浦按针 is the English navigator at the center of 14.武士威廉：大航海时代的日本和西方 and [[SamuraiWilliam|《武士威廉》]]. The episode presents him as a lower-status English seaman shaped by naval war, Dutch employment, and failed route searches before a disastrous Pacific voyage leaves him among the few survivors to reach Japan in 1600.

In Japan, Adams becomes valuable to [[TokugawaIeyasu|Tokugawa Ieyasu]] because he can explain European geography, Confessional Trade Conflict, navigation, shipbuilding, and the political difference between Iberian Catholic powers and Protestant English/Dutch traders. The episode says Ieyasu grants him land, a Japanese name, and samurai status, but it keeps his role bounded: Adams helps with diplomacy, shipbuilding, and trade access; he does not redirect the Tokugawa Shogunate / 德川幕府 away from later restriction.

Key Claims

• Adams’s story is useful because it joins biography to Early Modern Japan-Europe Contact, not because one foreigner single-handedly changes Japanese history.
• His voyage makes Oceanic Voyage Attrition concrete: the source tracks shipwreck, scurvy, hunger, violence, capture, and very low survival.
• Adams’s political value depends on being a practical mediator rather than a missionary; he can oppose [[Jesuits|Jesuit]] accusations without turning the episode into a simple Protestant hero story.
• His shipbuilding and navigation knowledge matter to Tokugawa Foreign-Trade Ambivalence because the regime wants technique and trade while fearing Christian political risk.
• [[Nioh|《仁王》 / Nioh]] amplifies Adams’s legend through fantasy, while the episode returns him to early-modern maritime and diplomatic history.
