Nobunaga

Nobunaga was Toranaga’s favorite son, official heir, and a general in his own right. His brief life is recalled as a tragedy of political entanglement: although Mariko describes him as brave, loyal, and innocent, he was caught up in his mother’s conspiracy against Dictator Goroda and died by Toranaga’s order at nineteen.

Identity and Position

Mariko recounts Nobunaga’s fate to John Blackthorne while explaining the history of Toranaga’s first marriage. Toranaga had married Lady Tachibana when he was eighteen and she was fifteen. Their son Nobunaga became Toranaga’s favorite and official successor, as well as a general. The account gives him military standing and dynastic importance, but no independent actions or ambitions beyond the family crisis that ended his life.

The Conspiracy and Its Consequences

Lady Tachibana secretly plotted to assassinate Dictator Goroda, whom she hated. Her scheme implicated Nobunaga despite his innocence, according to Mariko, and placed Toranaga and other prominent men in danger: Goroda was merciless and suspicious of those closest to him. Toranaga feared that, if he failed to punish the plot, Goroda would conclude that he too was involved and order his death. The conspiracy therefore turned a mother’s political act into a threat to her son, her husband, and their wider circle.

Death and Narrative Significance

Twenty years before the conversation, Toranaga ordered Lady Tachibana put to death and ordered nineteen-year-old Nobunaga to commit seppuku. Mariko frames the decision as an act Toranaga had no choice but to make under Goroda’s scrutiny. Nobunaga’s death is thus remembered not as punishment for personal disloyalty, but as the terrible cost of being drawn into a conspiracy he did not support. His fate also shadows Toranaga’s later position as a father and ruler: the heir he favored was lost through a political necessity created by another’s plot.
