Toranaga secretly activates Plan Five

Toranaga secretly activates Plan Five through a coded message to Sudara, turning a private contingency into a possible general mobilization for war. The order reveals both the scale of the preparations and their central weakness: the plan can trigger without Toranaga, but he believes its success depends on his own leadership.

The Secret Message

After Hiro-matsu has gone, Toranaga summons Kiri and tells her to send Sudara an immediate message by racing pigeons. She is to release three birds together at dawn and repeat the procedure at noon. The instruction is brief, but its repetition is a practical safeguard: Toranaga expects that some messengers may not get through, and he wants the message sent more than once.

The message says that all is well. That reassuring surface conceals its real instruction: disregard any other messages and activate Plan Five. Toranaga calculates that at least four pigeons may be lost to arrows, spies, or hawks, yet considers it enough that one gets through. Even if Ishido intercepts a bird, the code should prevent him from understanding what it carries unless he has somehow broken it. The scene therefore makes communication itself part of the plan: the order must travel through danger while appearing harmless to an enemy who may be watching.

A Code Shared by Four

The code is known to only four people: Toranaga, his eldest son Noboru, his second son and heir Sudara, and Kiri. That restricted circle makes the message difficult to decipher, while allowing the instruction to pass between the people positioned to act on it. Kiri is not given the whole explanation in the exchange; Toranaga gives her the operational task, and the reader learns the decoded meaning through his thoughts.

This division between the plain message and its concealed meaning creates a deliberate gap between what an observer could see and what the message commands. Its apparent reassurance is not evidence that the danger has passed. Instead, it is the signal for the opposite response: assemble the Yoshi Clan’s leaders and their most trusted counselors at the capital, Yedo, and mobilize for war. The code does not merely conceal information. It authorizes a sequence of actions that has already been prepared in advance.

The War Plan and Its Contingency

The signal for war is Crimson Sky. Under Plan Five, Toranaga’s assassination or capture would make the offensive inexorable, even if he could no longer lead it. Sudara, as heir, is to command an immediate, fanatical assault on Kyoto with all the legions, seeking control of the city and the puppet Emperor. The military attack is paired with secret insurrections in fifty provinces, prepared over years for this contingency. Targets including passes, cities, castles, and bridges have already been selected; the plan also has arms, men, and resolve behind it.

The design gives the message consequences far beyond a family communication. A threat against Toranaga is made the trigger for a coordinated war effort across multiple provinces, rather than an isolated succession crisis. The preparations are extensive, but the plan is conditional: it becomes inexorable if Toranaga is captured or killed. Its readiness does not guarantee victory, and the message initiates a response whose outcome still depends on who can lead it and command support.

Toranaga’s Doubt and the Stakes

Toranaga considers Plan Five a good plan, but doubts that Sudara can carry it through alone. He does not attribute the danger to cowardice, lack of intelligence, or treachery. In his judgment, Sudara lacks the experience and knowledge to lead the campaign and cannot yet bring enough uncommitted lords to his side. The difference is not simply between an able and an inept heir: it is between a prepared military mechanism and the political authority needed to make it work.

Two obstacles further complicate Sudara’s position. Osaka Castle and Yaemon stand in the way as an inviolate rallying point for the hostility and jealousy Toranaga has accumulated over fifty-two years of war. The plan can summon Toranaga’s forces and launch its provincial uprisings, but it cannot by itself remove that political obstacle or transfer his accumulated authority to Sudara.

The passage sets the scale of the contingency against Toranaga’s long experience of war. His conflict began when he was six and sent as a hostage into an enemy camp; he was reprieved, captured by other enemies, and pawned again until the age of twelve. At twelve, he led his first patrol and won his first battle. He remembers many battles and none lost, but also many enemies, now gathering together. Against that history, Plan Five is both a formidable preparation and an admission of vulnerability: the war can begin in his absence, while the man who devised it believes his heir may not yet be able to win it.
