Mariko’s Osaka protest turns an attempted departure from Osaka Castle into a public test of authority, samurai duty, and the hostage power Ishido exercises over those inside. When Gray guards bar her procession, Mariko refuses to treat their orders as a reason to abandon her duty to Toranaga. She stakes her life on that refusal, and the repeated clashes that follow make the cost of the impasse visible in the bodies left along the route. Ishido finally announces that the Regents have made an exception: Mariko and her party may leave at dawn. The concession grants the departure she demanded, but only after her threatened death has forced the castle’s restrictions into public view.

The blocked departure

Mariko begins the attempt by leaving with an escort that includes a vanguard of twenty Brown samurai. Her palanquin is open, and Kiri and Lady Sazuko follow close behind; Lady Sazuko carries her infant. Outside the castle walls, a Gray captain steps between the vanguard and Mariko’s palanquin and demands to see travel papers. Akira Yoshinaka, the captain leading the procession, replies that none are required. The opposing claims are immediately more than a disagreement about documents: the guards treat the castle’s permission as decisive, while Mariko’s party proceeds on the authority of Toranaga’s orders.

Mariko asks the Gray captain, Sumiyori Danzenji, to move aside and warns that otherwise she will order him killed. When he refuses, she tells Akira Yoshinaka to kill him. Yoshinaka attacks without hesitation, killing the captain with two blows. The vanguard reforms and moves forward, but an arrow strikes Yoshinaka in the chest. He dies as the procession halts again. The abrupt loss of its captain turns the effort to pass the gate into a succession of deadly confrontations rather than a single guarded departure.

A passage bought with lives

Mariko appoints Miyai Kazuko to take charge. He orders the procession onward, but twenty Gray samurai form a line across the road. Kazuko commands them to clear the way, and a series of evenly matched fights begins. As each Gray falls, another steps out from the waiting ranks; the Brown vanguard is gradually killed. The exchange is described as man against man, with the numbers dwindling until the last Brown, already wounded after defeating four opponents, is killed by the final Gray. Four Grays are wounded and eighteen are dead.

Kazuko advances to fight the surviving Gray, but Mariko stops him before he can begin another duel. She goes to Kiyama and formally asks him to order the men aside. Kiyama answers that the castle’s orders are legal and must be obeyed, although he offers to call a meeting of the Regents for a ruling. Mariko rejects the idea that a legal order settles her obligation: she says her samurai orders are clear and that being prevented from obeying her liege lord would leave her unable to live with the resulting shame. Kiyama agrees to call an immediate meeting, but Mariko distinguishes his business from hers and returns to the head of the column.

Kazuko announces himself as a captain of Toranaga’s Third Army and again demands that the Gray guards move. Biwa Jiro, a captain in Ishido’s garrison, refuses. Their duel ends with Kazuko victorious, but gravely wounded. He raises his sword and cries out for Toranaga, then tries to lead the procession onward. Arrows kill him before he can go far. His death changes the Brown samurai’s mood from fatalism to ferocity; another Brown officer forms a new vanguard while the remaining men gather around Mariko, Kiri, and Lady Sazuko.

A further group of Gray guards blocks the road. The next Brown assault is answered by cries for Toranaga and the Heir Yaemon, but once more the Browns are killed as fresh Grays step forward. Rather than order another officer and another group into the same exchange, Mariko takes Yoshinaka’s sword and approaches the Gray captain alone. She tells him that he knows who she is and asks him to move. He identifies himself as Kojima Harutomo of the Sixth Legion and refuses. Mariko eventually recognizes that she cannot force a passage without risking capture and the collapse of the whole attempt. She orders the column to stop and turns back.

The seppuku ultimatum

Mariko tells Kiyama that the guards have prevented her from doing her duty and obeying her liege lord. She announces that she will commit seppuku at sunset and asks Kiyama to serve as her second. Kiyama refuses to allow it. Mariko answers that unless she is allowed to obey her lord, she will carry out the threatened seppuku at sunset. Her ultimatum changes the standoff: what began as a dispute over papers and the right to pass now places the consequences of the castle’s refusal before its witnesses.

She bows and returns toward the gate. Kiyama and his men bow to her, as do those in the avenue, on the battlements, and at the windows. Mariko then goes to a secluded tea house and weeps alone for the men who have died. The public homage does not undo the violence or secure her release; instead, the scene leaves the demand for permission unresolved while making the human price of the obstruction unmistakable.

At the later confrontation, Mariko prepares to make good on the threat. She changes into a formal white death kimono, removes the green ribbon from her hair, and walks without looking back at Blackthorne. In the gateway, Brown and Gray samurai and samurai women assemble in formal ranks. Mariko kneels on a crimson coverlet, places her dagger before her, and allows her attendant Chimmoko to bind a white blanket around her waist so that her clothing will not be bloodied or disarranged. When Mariko asks Kiyama to act as her second, he has declined to assist her; she then asks Yabu, who agrees and takes his position behind her with his sword ready. Mariko asks him to wait until she has made the second cut, bringing the protest to the edge of its threatened consequence.

Ishido’s concession and its limits

Ishido arrives before sunset and points out that the appointed time has not yet come. Mariko says that she wishes only to obey her lord. As anger moves through the Brown samurai and Yabu prepares to spring at Ishido, Ishido reveals that Ochiba had asked the Regents, on behalf of the Heir, to make an exception for Mariko. The Regents have agreed. Ishido gives the permits to Sumiyori and says Mariko is free to leave at dawn.

The permission extends beyond Mariko. Ishido confirms that her men also have safe-conducts and directs Yabu, as senior officer, to collect their passes from his secretary. He tells the other women and samurai that they may apply to leave as well, though he mocks the practical value of departing for only seventeen days and condemns Mariko’s public threat as an arrogant spectacle. His announcement thus grants the immediate demand while retaining the distinction between her special permission and the ordinary application process available to others.

Ishido orders the Gray guards to withdraw from the gateway. Most leave; a token number remain in honor of the Browns. Yabu tells Mariko that she has won. She agrees, and Chimmoko unties the white blanket. The protest ends not with Mariko’s death or a forced passage through the guards, but with permission secured before the announced deadline. Its outcome reverses the apparent balance of power: the castle had used its guards and rules to hold the party in place, yet Mariko’s insistence that she would die rather than submit makes the restriction politically costly to maintain. The departure is permitted, while the dead and wounded remain the measure of what the delay demanded.
