Kasigi Omi, Lord of Anjiro

Kasigi Omi, Lord of Anjiro, is Yabu’s nephew, a local ruler responsible for Anjiro, and an increasingly consequential adviser in the contest between Yabu, Toranaga, and Ishido. His story turns on the strain between service and ambition: he can act as a dutiful organizer and shrewd military counsellor, yet a public humiliation makes him contemplate killing his own liege lord.

Position and Responsibilities

Omi’s political importance first appears through a secret message to Yabu: a barbarian ship has come ashore at Anjiro. The message reaches Yabu at dusk while Toranaga is away in Osaka, and it prompts Yabu to weigh the dangers of investigating the ship against the risks of remaining in Yedo. Omi’s report therefore carries consequences beyond the village: it draws Yabu toward Anjiro at a moment when the neighboring daimyos are being kept in Yedo as security for Toranaga’s return.

When Toranaga does return, Omi’s responsibility is visible in the welcome he has prepared. Acting on Yabu’s orders, conveyed from Osaka by carrier pigeon, Omi mobilizes the village and every able-bodied man within twenty ri. He spends heavily to ready the fief, and the foreshore is carefully arranged for the arrival: the villagers wear their best clothes, the fishing boats and nets are orderly, and the beach has been raked. Omi insists to Igurashi that the preparations are his responsibility because Anjiro is his fief. His confidence contrasts with Igurashi’s warning that Toranaga may punish the entire region if anything has been overlooked.

A Breach with Yabu

Omi’s position in Yabu’s household is not merely political. He is Yabu’s nephew and a retainer expected to observe his lord’s authority. That hierarchy is sharply enforced when Yabu tells him that he handled a matter involving Blackthorne badly: the consort was responsible for protecting Blackthorne and his property, and Blackthorne had the right to wear swords. Yabu also reminds Omi that Blackthorne is his honored guest and orders him to apologize.

Omi immediately kneels before Blackthorne, apologizes, and returns to his place. His outward obedience conceals a decisive change: inwardly, he becomes consumed by the idea of killing Yabu. He recognizes the act as unthinkable—not simply a challenge to a relative, but an attempt to kill the head of his clan and his own liege lord. The contrast between the composed apology and the concealed resolve establishes how readily public discipline can mask a private struggle for power.

Counsel on War and Allegiance

Omi’s military advice reveals a strategic intelligence that extends beyond his immediate resentment. He urges Yabu to be patient, arguing that Blackthorne has given Toranaga priceless knowledge and that reports from Yabu, alongside Naga’s private reports, have carried that knowledge onward. Omi believes Yabu’s force of five hundred guns, reinforced by another three hundred, could deliver overwhelming power once—but only once, because an enemy who survives the first encounter will learn how the weapons and troops are used. The advantage, he argues, depends on choosing the right battle rather than spending the new firepower prematurely.

When Yabu objects that Ishido may soon obtain the Emperor’s mandate, Omi answers with a legal and political argument. With the Council of Regents dissolved, he contends, there is no functioning council to issue binding orders; the document threatening Yabu does not by itself compel every daimyo to obey. Omi distinguishes Ishido’s allies from the lords who might still choose their own course, and urges Yabu to wage the coming conflict on his own terms rather than Ishido’s. His case is concrete: Toranaga has never been defeated in battle, favors ships and trade, has given Yabu his sword and control of the guns, and promises him the province of Ikawa Jikkyu if victorious. Ishido, by contrast, would give Yabu’s hereditary fief of Izu to Jikkyu. Omi concludes that Toranaga is Yabu’s only viable choice and counsels him to go with Toranaga.

Place in Toranaga’s Plans

Omi is also present when Toranaga explains Crimson Sky to the assembled advisers. Toranaga describes a final, concentrated assault on Kyoto: a rapid advance with his legions to seize the capital, free the Emperor from the forces surrounding him, and seek a new mandate to replace the compromised Council. The disclosed plan involves leading eighty to one hundred thousand men while leaving Toranaga’s lands, flanks, and retreat exposed; hidden cadres are intended to rise in other castles and provinces at the same time. Omi’s presence places him among those entrusted with hearing the public outline of this perilous strategy, though the concealed preparations are not disclosed to the group. Across these episodes, he serves as both a local administrator and a political interpreter of force, while his private decision to kill Yabu remains unresolved in the evidence presented.
