Mariko’s meeting with Father Alvito at the unfinished church foundation turns confession into a political exchange. Seeking spiritual counsel, she instead gives the Jesuit intelligence about Lord Toranaga, Lord Zataki, and a reported conspiracy against Lord Kiyama. In return, she secures Alvito’s promise to seek protection for Anjin-san and to carry her warning to the Father-Visitor. The scene shifts the value of the encounter from private absolution to consequential, shared knowledge: Alvito leaves persuaded that Toranaga’s apparent defeat is a deception, while Mariko’s information enters the Church’s deliberations.

At the Church Foundation

Mariko comes to the site as dawn approaches, wishing both to see a ship leave and to be confessed. The ground is barely hallowed, but Father Alvito agrees that her confession can be the first in that place. She also asks whether he can say Mass there. The setting joins a religious beginning to an unsettled political moment: before the church is fully consecrated, it becomes the place where Mariko seeks spiritual recognition and delivers information that may alter the Church’s response to the struggle around Toranaga.

The exchange is private, though not wholly solitary. Brother Michael kneels in prayer, and two servants wait nearer the shore. Mariko keeps her veils in place, so Alvito cannot see her face. Beyond them, the ships move southwest; the galley’s oars dip together, and the wind and sea are calm. These visible details frame a conversation whose political implications are much less settled than the water. Alvito watches the departing vessels while trying to distinguish fact from fancy in what Mariko tells him.

A Promise Before the Disclosure

Mariko asks that Anjin-san’s life be spared in return for knowledge. Alvito answers that he has no authority to give or withhold it. She narrows the request: Christians should be instructed not to take Anjin-san’s life as a sacrifice to God. Alvito’s first answer establishes the limit of his personal power; Mariko’s proposal instead asks him to use the influence he does possess among Christians.

She presses for a more substantial commitment before revealing her information. If what she tells him proves valuable, she asks him to do everything in his power to succor and guard Anjin-san, provided that doing so does not directly oppose the Church. Alvito accepts that condition and promises to put her request before the Father-Visitor. Only after securing this agreement does Mariko explain her reasoning about Lord Toranaga and the hoax. Alvito immediately recognizes the force of her argument and realizes that he had misunderstood the situation. The bargain is therefore not a simple exchange of secrets for protection: Mariko makes Alvito’s obligation explicit, and his new understanding gives the requested intervention greater urgency.

The Reported Plot and the Balance of Power

Mariko adds a rumor about Lord Kiyama’s danger. Onoshi is said to plan to poison him at the Feast of the Blessed Saint Bernard. If Lord Kiyama dies, Onoshi’s son is expected to inherit all of Lord Kiyama’s lands, and Ishido has allegedly agreed to that arrangement on the condition that Lord Toranaga is already dead. Mariko does not present this as established fact. When Alvito asks for proof, she says she has none, but identifies Lord Harima’s party as having access to the knowledge. She also declines to say who told her, deliberately leaving the source undisclosed.

Alvito connects the rumor to the breach of confession: Uraga had been Onoshi’s confessor, and Alvito concludes that Uraga violated the confessional seal by telling his liege lord what he had learned. Mariko herself allows that the secret may be false, while saying that she believes it; only God, she observes, knows the truth. The scene thus marks a boundary between intelligence and proof. Alvito is not given confirmation, but the particulars and their political logic persuade him enough to reassess what is happening.

Mariko’s warning extends beyond the alleged poisoning. She argues that Lord Zataki cannot be trusted, because he would recognize that Lord Toranaga’s promises to him are ultimately empty if Toranaga must eventually eliminate him. She imagines the consequences if Zataki received Sudara, Lady Genjiko, and their children into his hands: he could destroy them and attack Toranaga’s northern defenses, forcing Ishido, Ikawa Jikkyu, and others into action. In her assessment, Toranaga could be overwhelmed if that pressure united his opponents. Her point is not that one side will certainly win, but that Toranaga is vulnerable to a wider alignment against him.

Consequences and Significance

Mariko argues that only Lord Toranaga can prevent perpetual war and makes her appeal for peace as a woman who does not want an everlasting conflict. Alvito concedes that Toranaga may be the only person capable of preventing it. The exchange changes his stance: overwhelmed but uplifted, he thanks her and commits himself to what he has agreed. The scene does not establish that the reported plot is true or that the Church will act as Mariko hopes. It does establish that her assessment has persuaded Alvito to help rather than dismiss her warning.

Alvito then asks Mariko to carry a dispatch to the Father-Visitor. It is to be verbal, not written: she must relay everything she told him and everything he told her. Mariko agrees, and Alvito asks her to affirm the promise before God. The confidential conversation therefore becomes a channel for further transmission. Its decisive consequence is not a proven alliance or a guaranteed rescue, but a change in what Alvito understands and a commitment to pass that understanding onward. At the church’s barely hallowed foundation, confession, political judgment, and a messenger’s promise converge.
