The Kantō region matters in the novel not only as territory but as leverage: it figures in a proposed alliance with Lord Zataki, in Yabu’s calculations about his own advancement, and in the struggle to secure rice after a devastating storm. Its value shifts with the needs of the moment—from a possible reward for allegiance to a harvest that could sustain the Empire.

A Prize in a Political Bargain

In one account of Toranaga’s plans, Buntaro is said to have been sent secretly to Lord Zataki with a new offer. The proposed price of Lord Zataki’s allegiance is the Kantō region, to be granted once Toranaga has regained the presidency of the Council of Regents under a new mandate. The account presents this as a calculated inducement, not as a completed transfer: securing Lord Zataki would place Toranaga a quarter of the way toward Kyoto.

The same analysis links the proposed bargain to hostages. Lord Sudara, Lady Genjiko, and their children are expected to visit their grandmother at Takato, a circumstance interpreted as a way to cement the pact between the half-brothers. In this reading, the Kantō region is part of a larger political arrangement in which territory, allegiance, and family members’ safety reinforce one another.

Yabu’s Competing Calculations

Yabu is advised that Toranaga will never actually give the Kantō region to Lord Zataki, whom the adviser describes as a continuing threat. Instead, Lord Zataki might be maneuvered into seeking the foremost place in battle, where a stray bullet or arrow could remove him. This is presented as a prediction about Toranaga’s intentions, not a confirmed plan or outcome.

Yabu receives a different promise. Because he is not Toranaga’s kinsman and therefore poses no equivalent succession threat, he is told that service could make him Toranaga’s devoted vassal and earn him the Kantō region. The proposed route runs through military command: Yabu should lead the Musket Regiment and support Toranaga with judgment rather than follow every order blindly. The region thus becomes an incentive for Yabu to choose a side, while the possibility of battlefield death makes that advancement dangerous as well as attractive.

The Harvest and the Wider War

After the storm, much of the local harvest is reported flattened, while the storm’s main force has struck Kyushu and part of Shikoku and caused tens of thousands of deaths. The extent of the damage is still unknown. Against that uncertainty, the Kantō region’s prospective crop takes on an Empire-wide importance: if its fields escape damage during the season, their rice may have to feed the whole country for this year and the next.

Mariko observes that such a harvest would be better under Toranaga’s control than Ishido’s. The exchange makes control of the region more than a question of territory or personal reward. Whoever commands its grain may gain a decisive resource at a moment when war threatens and other regions’ crops have been ruined. Yet nineteen days are not enough to bring in the harvest, even with prayers, so the region’s potential value is constrained by the immediate demands of time and agriculture.
