Jikkyu Is Poisoned to Death

Ikawa Jikkyu’s poisoning turns a concealed killing into an opening for military advance. Reported to Toranaga as a death from sickness, it is soon exposed as a paid plot linked to Kasigi Mizuno and a helper placed in Jikkyu’s personal kitchen. The news removes a powerful obstacle from the southern route, while the discussion around it makes the story’s hard equation plain: treachery is not merely a private crime but a weapon with a price and a strategic purpose.

The Report and Its Concealment

Yabu brings the news to Toranaga after hearing it during the night: Jikkyu has died, apparently after being sick for some time. His informant says the death occurred two days earlier. The report gives the death the outward shape of an illness, and Yabu presents the information with unconcealed satisfaction. The timing matters: Toranaga already knows the secret when Yabu reports it, having received the information on the day he left Mishima. He pretends to be startled, keeping his knowledge—and the appearance of surprise—under control.

The account of sickness is not the truth of the event. When Toranaga asks about the price of this supposed illness, Yabu laughs and explains the chain of payment. Kasigi Mizuno, Yabu’s brother, passed on money acquired from John Blackthorne to a cook’s helper who had been planted in Jikkyu’s personal kitchen. The evidence thus points to a poisoning arranged through access to the household’s food, though it does not describe the physical act or identify what was administered. The killing remains offstage; what the scene reveals is its route through money, a kitchen, and a trusted informant’s report.

A Vacancy on the Southern Route

Yabu immediately translates Jikkyu’s death into a military opportunity. He asks whether the southern route is now open and urges an immediate attack along the Tokaido Road. In his assessment, Izu is secure, while Suruga and Totomi are left vulnerable by the old rival’s removal. He presses the point with the confidence of a man who sees the balance of power shifting in his favor.

Hiro-matsu gives the proposal its operational detail. If Toranaga’s forces can seize the road as far as Utsunoya Pass, control the bridges, cross the Tenryu quickly, and secure their communications, they could cut into Ishido’s position from the south. The plan would also contain Zataki in the mountains, reinforce the attack along the Tokaido, and open a rapid advance toward Osaka. Jikkyu’s death does not itself win this campaign; rather, it changes what the commanders believe they can attempt. The killing creates a vacancy in the strategic landscape, and the proposed march is the immediate effort to exploit it.

Competing Judgments of the Killing

The news lands among men already divided over the means of war. Hiro-matsu considers the guns and strategy under discussion dishonorable and unnecessary, insisting that victory should not require such treachery. Yabu answers that without the guns and the strategy they will lose: this is a modern war, and those methods offer a chance to win. His argument places the poisoning within a wider contest between inherited ideas of honorable combat and calculated methods intended to secure victory.

When Toranaga makes Yabu explain the payment to the others, Yabu is not displeased. He recognizes the scheme as clever and devious, and calls the price cheap in exchange for the southern route. Hiro-matsu, by contrast, calls the story disgusting. The difference is not over what happened but over what its usefulness can justify. Toranaga’s response—that treachery is a weapon of war—does not erase the moral objection; it recasts the act as part of the contest for power.

Consequences and Significance

Jikkyu’s death also settles succession, at least as Yabu understands it: his son Hikoju is the heir. Buntaro dismisses the son contemptuously, and Yabu agrees that he is no more than a whelp. Their assessment helps explain why Yabu sees the killing as an unusually favorable exchange: the rival is gone, and the successor is judged weak. The scene does not establish what Hikoju will do or whether the southern advance will succeed; it records the expectations that the death immediately produces.

The episode binds together information, covert action, and open strategy. Jikkyu’s sickness is the public appearance; the helper in his kitchen and the payment through Kasigi Mizuno are the concealed mechanism; the proposed march is the political and military consequence. Even the money’s origin ties the plot to John Blackthorne, although the passage does not say that Blackthorne arranged the payment or knew how it would be used. By making the cost explicit and setting Yabu’s satisfaction against Hiro-matsu’s revulsion, the scene presents the poisoning as both a tactical opening and a test of the limits its participants place on wartime conduct.
