Blackthorne and Mariko’s intimacy while Buntaro is presumed dead

Blackthorne and Mariko’s intimacy while Buntaro is presumed dead is a private bond formed under the pressure of a marriage Mariko resents and a political world in which discovery could be fatal. Its brief opening is inseparable from her desire for Blackthorne, her refusal to submit to Buntaro, and the knowledge that Buntaro’s survival has altered what the intimacy means.

A marriage shaped by duty and resentment

Mariko explains that she married Buntaro to please Goroda and her father, not from affection. She recalls being young when the marriage was arranged and says that, had she known Goroda’s character, she would have understood the cruelty of the choice more clearly. In her account, Goroda drove her father to treachery; she bitterly imagines that without him her family might have remained alive and honored. Her history therefore joins her marriage to a wider grievance about political violence and the destruction of her family’s standing.

She describes the relationship with Buntaro as hatred rather than reconciliation. When Blackthorne tells her that the harm she suffers is not her fault, she insists that she is responsible and identifies herself as Akechi Jinsai’s daughter. Her sense of identity does not let her set aside the shame associated with her father’s treachery. She says Buntaro has the right to beat her and that she wishes he would, because even that might spare her the endurance of shame. The exchange shows how differently Blackthorne and Mariko understand her position: he offers compassion, while she frames her suffering through family identity, responsibility, and the obligations she believes she must bear.

Intimacy as desire and refusal

Mariko tells Blackthorne that her conduct toward Buntaro is not simply helplessness. She believes she could placate and manipulate him by performing the fear and submission he expects, but refuses to do so. She calls that refusal her revenge: a response to her father’s treachery, her eight years away, and the order that returned her to a life she did not choose. She also says that she once gave herself to Buntaro freely, despite detesting him from their first meeting, but will never do so again. In that account, her withholding is an act of resistance within a marriage whose formal claims remain powerful.

Her decision to go to Blackthorne has a different motive from the one she gives Fujiko. She claims to have gone for the saké, amusement, and curiosity; the narration makes clear that these were excuses. She wanted Blackthorne, had never had a lover, and believed that if she did not act then, she might never have another chance. The choice is specific, not interchangeable: she wants Blackthorne alone. After going to him, she is described as transported, giving the encounter an emotional force that contrasts with her account of the loveless marriage she endures.

Buntaro’s return and the changed meaning

Fujiko privately asks whether Mariko would have gone to Blackthorne had she known Buntaro was alive. Mariko answers no, but the narration identifies that answer as a lie. The contradiction leaves the intimacy suspended between a desire she acted upon and the limits she recognizes once her husband’s survival becomes known. Her earlier choice took place while Buntaro was believed dead; his return does not erase what happened, but it makes concealment more urgent and the possibility of continuing the relationship more dangerous.

In a later exchange with Blackthorne, Mariko denies that anything in her has changed. Blackthorne observes that a spark has gone out of her, and she attributes her state to relief that Buntaro is alive after she had been certain he was dead. His response—that this relief has nevertheless made a difference—registers the change she disavows. Her relief is not evidence that the marriage has become loving: she has already described it as a bond of hatred. Instead, it marks the emotional complication of Buntaro’s return and the abrupt narrowing of the space in which she and Blackthorne could be together.

Secrecy, danger, and political value

Toranaga considers whether Blackthorne went after Buntaro with pistols because of Mariko. He suspects that the lovers have been intimate, but his reflection remains an inference rather than a disclosure from either of them. He judges that any intimacy must remain a perpetual secret, since Buntaro might kill both Blackthorne and Mariko if he learned of it. Toranaga also refuses to send Blackthorne against Buntaro: he needs Blackthorne and Mariko more than he needs Buntaro. The relationship thus enters the political calculations of a lord who sees the danger clearly but treats both lovers as people whose continued usefulness matters.

Toranaga’s thoughts also expose a broader tension in his own reasoning. He remembers advising the Taikō about a foreigner who killed a man to marry a merchant’s daughter, then objects to maintaining one law for Japanese people and another for foreigners. Yet he still approaches this particular danger through calculation: the affair is tolerable if hidden, and Buntaro must be kept alive if possible because Blackthorne and Mariko are valuable. The lovers’ privacy is consequently more than a personal refuge. It is a fragile condition maintained amid a marriage’s claims, the threat of violence, and the competing interests of the political household around them.
