Izu threatened with isolation by Ishido’s forces

Izu threatened with isolation by Ishido’s forces describes a moment when Lord Yabu sees his province and Kwanto becoming strategically cut off, with Ishido’s political victory seemingly near. The crisis is not presented as a completed military encirclement: it is a narrowing window for communication and choice, made urgent by a renewed Council of Regents, a looming summons to Osaka, and Yabu’s fear that delay will leave his clan exposed.

The News That Turns Isolation into a Crisis

Nebara Jozen leaves Yabu’s presence surrounded by heavily armed men, after delivering news that changes the meaning of the encounter. Once Jozen is gone, Yabu demands to know who betrayed him. Igurashi dismisses the guards from earshot and identifies Yedo as the likely source of the breach, reasoning that security at their present location is sound. Yabu takes this as confirmation that he has been betrayed and is isolated: he names Izu and Kwanto as isolated too, and concludes that Ishido has won.

The perceived isolation is therefore more than a matter of territory. Yabu suspects that information has reached him through a compromised channel, while he cannot be sure what Toranaga knows or when he can act. His conviction that Toranaga has left him in a trap makes the danger feel immediate, even though the political timetable still leaves a brief interval for intervention. This gap between Yabu’s sense of entrapment and the remaining time to maneuver drives the scene.

The Council’s Clock and the Geography of Allegiance

Yabu believes the Council of Regents will be in power again in twenty days. He points to the four Regents’ agreement to Ito Teruzumi’s appointment as the reason the Council can meet, and he treats that approaching session as a decisive change: once it convenes, he expects to be compelled to obey. Omi counters that there is still time to act before the Council meets. Yabu, however, measures that interval against his own political and military vulnerabilities, not as an open opportunity but as a countdown.

Omi also challenges the assumption that Toranaga has already been informed. He argues that Iwari, Mikawa, Totomi, and Sugura are hostile to Toranaga and to anyone allied with him, and therefore would not warn him. On this reasoning, Toranaga may not yet know what has happened. Omi urges Yabu to send him a detailed account of Jozen’s visit and its implications, turning the risk of broken communication into a reason to communicate at once.

The geography matters because Yabu’s position depends on relationships among neighboring powers, not simply on the security of his own stronghold. Omi presents the hostile territories as barriers to information and assistance; Yabu sees the same political landscape as proof that Ishido has prevailed. Neither man treats the situation as settled by geography alone. The question is whether Yabu can still reach Toranaga and act before the Council’s authority is restored.

Omi’s Appeal and Yabu’s Countercalculation

Omi asks Yabu to align with Toranaga, arguing that Ishido will eventually betray him and that the danger extends to Izu and the Kasigi house. He invokes Toranaga’s Minowara lineage and contrasts it with Ishido’s origins, then recalls Ishido’s conduct in Korea, where, according to Omi, Ishido left Buntaro and their forces to fight their way out. Omi’s appeal is at once a warning about Ishido and an argument that Yabu should trust Toranaga instead.

He also makes a practical case. Omi says Yabu need not leave for Osaka for ten days, or fourteen if he travels by forced march, and that there is time to warn Toranaga. Yabu answers that he needs at least two months to train his regiment. Even if the men were already trained, he doubts that he and Toranaga could defeat everyone else. He fears that failing to appear when the Council convenes would bring death not only to him but to his entire clan, including Omi. His preference for supporting Ishido follows from that immediate threat, even as Omi warns that Ishido will consume the very ally he is asking Yabu to become.

Omi’s argument also draws on the resources and promises attached to Toranaga’s alliance. He reminds Yabu that Toranaga gave him his sword and control of the guns, and says the guns could secure a victory through surprise. He contrasts Toranaga’s interest in ships and trade, including the barbarian’s navy, with his prediction that Ishido would close the Empire. Omi further claims that Ishido would give Yabu’s hereditary fief of Izu to Ikawa Jikkyu, whereas Toranaga would give him Jikkyu’s province. These are Omi’s arguments to Yabu, framing allegiance as a choice between anticipated dispossession and a potential enlargement of power.

A Narrow Window, Not a Settled Outcome

Igurashi agrees with Omi that killing Jozen would be dangerous and irreversible. Instead, he suggests that Jozen’s future messengers might disappear, perhaps being blamed on bandits. He then recalls that Jozen’s pack horses carried two panniers of carrier pigeons. That detail makes the communications crisis concrete: information can travel without another messenger appearing at Yabu’s residence, and the effort to contain the news risks widening the intrigue rather than resolving it.

The scene leaves Yabu’s choice under pressure rather than reporting a final resolution to the isolation. He sees the approaching Council, his untrained regiment, and the threat to his clan as reasons to submit to Ishido; Omi sees the same interval as a last chance to alert Toranaga and preserve Izu. The state of isolation is thus political and provisional: Yabu may be cut off, but Omi insists that the channels and time for action have not yet closed. Their disagreement turns the province’s vulnerability into a test of judgment—whether apparent inevitability is already defeat, or an alarm that still permits a different alliance.
