Yabu-sama

Yabu-sama is the daimyo of Izu, Omi’s uncle, and a provincial lord whose hunger for military and political power shapes his dealings with both Toranaga and Ishido. When a foreign ship arrives, he sees in its weapons a chance to change the balance of power—and perhaps his own rank. Yet even when he offers Toranaga his help, he refuses the ordinary submission of a vassal: Izu, he insists, is his by inheritance, and he will not give it away.

Identity and Rule

To Mura, Yabu-sama’s rule is a daily burden. Mura thinks of his cruelty and lack of honor, and of how he deprives villages of their rightful share of the catch and the crops. The villagers are not merely watching a contest between distant great lords; they are already subject to Yabu-sama’s power, and fear being caught between him and the larger forces of Toranaga and Ishido when war comes. Mura cannot tell which side Yabu-sama will choose, or whether the villages will be safe under either.

That account makes Yabu-sama’s political uncertainty inseparable from the local costs of his rule. His people experience him not as a distant strategist but as the authority who controls their produce and presses down upon their lives. His later willingness to bargain with powerful rivals does not erase this picture of a ruler whose ambition is felt from below.

The Ship and Its Weapons

Yabu-sama’s interest in the foreign ship is immediate and consuming. Omi has sent him a secret message, and when Yabu-sama arrives, weary and spattered with mud, he asks whether the cargo has been inspected. Omi has kept the vessel sealed until his lord could come in person; the holds contain crates and bales, and Omi turns over the keys he has confiscated. The ship is valuable to Yabu-sama before its full contents are known, but the weapons soon make its value unmistakable.

After learning what the ship carries, Yabu-sama orders everything taken ashore and the muskets repacked in their crates, covered with nets or sacking. He counts five hundred muskets, more gunpowder and shot than Toranaga possesses across the Eight Provinces, twenty cannon, five thousand cannon balls, and crates of fire arrows. Concealment is part of the opportunity: the guns and ammunition are not simply spoils to display, but an arsenal to move and use without drawing attention.

The captured wealth changes his sense of what is possible. In his bath, he imagines rebuilding the castle keep, buying special horses for the cannon, expanding his espionage network, and using silver to bribe cooks into poisoning Ikawa Jikkyu. These are possibilities he considers, not actions the evidence shows him carrying out. Their range—from fortification and intelligence to assassination—reveals how quickly he converts possession into schemes for influence.

Ambition and a Conditional Offer

Yabu-sama does not want merely to support one side in the coming conflict. He imagines using the guns to make either Ishido or Toranaga win, depending on which choice best serves him, and then rising into the vacant place left by the loser. His private ambition reaches as far as becoming the most powerful regent, and even Shōgun. The ship has supplied the material means for these fantasies; it has not yet supplied a settled allegiance.

That calculation informs his later disclosure to Toranaga and Hiro-matsu. Asked what Ishido offered him, Yabu-sama says that Ishido promised him Jikkyu’s head and Jikkyu’s province once Toranaga had been killed. Yabu-sama presents his own plan for the guns in answer to Toranaga’s questions about how he could help. Its central military idea is a regiment of five hundred gun-samurai trained to act together, supported by the twenty cannon. Hiro-matsu reacts with astonishment at the proposed firepower. Yabu-sama is therefore not only a collector of captured weapons: he offers a way to turn them into an organized force.

The Terms of Alliance

Before speaking privately with Toranaga, Yabu-sama prepares for the possibility that the interview will end in his death. He has written final letters to his wife and mother and sealed his will. He wears the Murasama blade in a battle-honored scabbard. When Hiro-matsu leads him through an ironbound door and up to a guarded redoubt on the battlements, Yabu-sama senses danger but does not show fear. Toranaga, however, tells him that he has brought him there to talk and to see the dawn, not to take his head.

Toranaga offers him rule over Izu, Suruga, and Totomi if Toranaga wins the war, then asks whether Yabu-sama will become his vassal and accept him as liege lord. Yabu-sama refuses that status without hesitation. He is willing to be Toranaga’s ally and leader in war, to put his life and possessions on Toranaga’s side, and to remain lesser in rank; he is not willing to surrender power over Izu. He grounds that refusal in his oath to his father and in the Taikō’s confirmation of the hereditary fief for his family and successors. He says he swore not to accept another liege lord until the Taikō’s heir came of age.

The exchange defines both the reach and the limit of Yabu-sama’s cooperation. He can offer men, weapons, and support, but he treats hereditary sovereignty as a boundary no reward can dissolve. His position is not simple loyalty to Toranaga: it is an alliance negotiated alongside a defense of his own independent authority.

Departure and Political Significance

When Yabu-sama leaves Osaka, he is astonished to be going with his head, John Blackthorne, the guns, and the rest of his gains. He sends urgent messages by carrier pigeon to his wife in Yedo, arranging preparations at Mishima, and to Omi in Anjiro. These communications connect his escape from Osaka to the practical work of securing his position at home. His departure is not a resolution of the contest between the great lords; it carries his uncertain allegiance and newly acquired military assets back toward Izu.

Yabu-sama’s significance lies in the way he joins provincial grievance, military modernization, and self-interested negotiation. The arsenal gives him leverage, but his plans remain attached to personal advancement: he considers which rival to empower, what territory to acquire, and how far his rank might rise. At the same time, his refusal to yield Izu exposes a political limit that even his ambition does not cross. He can bargain with the great lords, but he insists on doing so as a power in his own right.
