Japan is on the brink of civil war. The elderly (the former regent) is dead, leaving a child heir. A Council of Five Regents rules in his name, but the regents are deeply divided. The most powerful and ambitious is Lord Ishido Kazunari , who wants to become the next Shōgun (military dictator). The only regent strong enough to oppose him is Lord Yoshi Toranaga , a brilliant and cunning strategist.
The story begins in 1600, in feudal Japan. An English ship, the Erasmus , piloted by the experienced sailor , washes ashore near the coast of a village controlled by Lord Yoshi Toranaga, a powerful regional lord. Blackthorne is a "barbarian" (a foreigner) and a Protestant heretic in the eyes of the Portuguese Jesuits who already have a strong foothold in Japan. The Jesuits, led by Father Carlo dell’Aqua, control the trade in guns, silk, and knowledge, and they see Blackthorne as a threat to their power. Shogun
In Osaka, Mariko becomes a heroine. She refuses to bow to Ishido, confronts the Jesuits, and demands her right to leave. When Ishido surrounds her with soldiers, she walks calmly to the castle gate. The standoff ends in chaos: assassins sent by the Jesuits (or by Ishido) attack. Mariko is mortally wounded while shielding Blackthorne and Toranaga’s family. Her death is the ultimate act of giri —duty to her lord—and her final rejection of Ishido’s power. Japan is on the brink of civil war
