Shōgun: A Novel of Japan (Plot Summary)

Plot Summary

The Shipwreck

At the opening of Shōgun: A Novel of Japan, John Blackthorne, English pilot of a Dutch ship named Erasmus, arrives in Japan hoping to break the Jesuit trade monopoly on the Far East. Instead, he becomes embroiled in the feudal politics of a war-torn nation. His involvement begins as soon as he reveals his dislike for a Jesuit priest. Lord Omi and Lord Yabu see that Blackthorne may be the key to getting rid of the Jesuits. In addition, Black-thorne has the knowledge necessary to create a musket regiment for Yabu — so he can be Shōgun.

Before Yabu can secure Blackthorne, Lord Hiro-matsu, the trusted aid of Lord Toranaga Yoshi, persuades Yabu to give the ship, its contents, and its pilot to Toranaga. Hiro-matsu then takes them all to Osaka aboard a galley piloted by Vasco Rodrigues, a Portuguese merchant. He tries to kill Blackthorne, but Blackthorne saves his life instead.

Osaka

For Blackthorne, Osaka makes the "Tower of London look like a pigsty." Inside the castle, Blackthorne meets Toranaga, President of the Council of Regents and overlord of the Kwanto. Father Alvito is present to interpret and to negotiate with Toranaga about the Black Ship — the trading vessel under Jesuit control whereby the Japanese obtain goods from China. Toranaga decides Blackthorne could be his secret weapon if he learns to be Japanese. Lady Mariko will be his teacher.

In order to keep Blackthorne from his rival Ishido, Toranaga has Blackthorne thrown in prison. There, Blackthorne learns the history of the Jesuits in Asia from Father Domingo, a Franciscan and enemy of the Jesuits. After a few days with Father Domingo, Ishido's guards kidnap Blackthorne. While they attempt to steal Blackthorne away, Toranaga's men in disguise steal him back. By coincidence, Yabu arrives and rescues Blackthorne. Ishido, consequently, loses face, while Yabu and Blackthorne feel closer to Toranaga. Hiro-matsu and Toranaga get a good laugh.

The Escape

With information from Blackthorne, Toranaga begins to understand how European affairs impact Japan. More immediately, Ishido is ready to orchestrate the political demise of Toranaga. Therefore, Toranaga disguises himself as Lady Kiri and sneaks out of Osaka, but Blackthorne notices the trick.

As the party nears the last checkpoint, Ishido stops them. Blackthorne risks his life to prevent Ishido from noticing Toranaga. He succeeds, and the party makes it to the galley, which is barricaded in the harbor by samurai in fishing boats. Toranaga cuts a deal with the Jesuits, and they take him out of the harbor. Rodrigues repays Blackthorne a life by allowing him to pilot the galley alongside the Portuguese vessel as it leaves. As a result of enabling Toranaga's escape, Blackthorne is made Hatamoto — a high-ranking samurai.

Blackthorne's Education

Back in Anjiro, Toranaga avoids Yabu's traps. He does this by honoring Yabu in front of all his men, who cheer "Toranaga!" Then, Toranaga quickly exits before Yabu realizes he has been manipulated.

That night, Blackthorne attempts suicide to protest Yabu's order that the entire village be killed unless he learns Japanese. To their surprise, Black-thorne was not bluffing, but Omi stops his arm. The Japanese now see Blackthorne as a true samurai.

While working to train Yabu's musket regiment, Blackthorne falls in love with Mariko, who is teaching him Japanese. Blackthorne discovers that to progress in his studies, and to survive, he must become Japanese.

The Game Begins

Toranaga returns to Anjiro and begins to implement his war strategy. First, he develops a false personality — one that is indecisive and weak — in order to make everyone think he is beaten. Second, he does everything in his power to gain time.

After speaking with his officers, Toranaga tells Mariko she must go to Osaka with an order for his ladies to join his procession to the castle. Then he converses with Blackthorne about the Black Ship. An earthquake disrupts the meeting, and Blackthorne saves Toranaga again. As a reward, Blackthorne receives a fief and several declarations of friendship.

Yokose

Lord Zataki meets Toranaga, on behalf of the Council, at Yokose. Toranaga tricks Zataki into revealing both of the Council's messages. First, the Council asks Toranaga to come to Osaka and declare obedience. If the invitation is refused, the second message orders him to commit seppuku — suicide. Toranaga promises an answer tomorrow. Toranaga now knows that Ishido has an alliance, and he has gained a day through the rules of diplomatic ceremony. Yabu also accepts a scroll and must go to Osaka without delay. At noon the next day, Toranaga says he will accept the invitation. Toranaga gains more time this way because he must arrive in Osaka with all the trappings of his societal position.

Back to Yedo

Toranaga orders everyone back to Yedo by different routes. Toranaga travels quickly by way of Anjiro to collect his men and use the galley. Back at Yedo, he begins to probe Ishido's alliance for weaknesses. Mariko and Blackthorne, meanwhile, take a lingering route overland to Yedo. On the way, they consummate their affair. When they arrive at Yedo, the love affair ends.

At Yedo, Toranaga blackmails the Jesuits by openly encouraging Blackthorne's plan to steal the Black Ship. Goyoko, a madam who is trying to create a red-light district, gives Toranaga several secrets to use against Zataki and the Christian Lords. Toranaga immediately offers Zataki a deal. While waiting for a response, Toranaga continues to act as a defeated man. He tests the loyalty of his son and heir, Lord Sudara, and then disinherits him to thwart treason plans. When he hears that Zataki accepts his offer, he sends Sudara to Zataki as a hostage. Coincidentally, Yabu succeeds in killing Lord Jikkyu — thus taking both Zataki's and Jikkyu's armies out of the field.

With things falling into place, Toranaga brings Hiro-matsu into his confidence. A relieved Hiro-matsu stops the disintegration of the officer ranks. Next, Toranaga releases Mariko, Yabu, and Black-thorne to open up Osaka. As they prepare to leave, Mariko gives information to the Jesuits in order to keep Blackthorne safe should Toranaga lose.

Mariko's Poem

Toranaga cannot act until Ishido is forced to give up the hostages in Osaka and every lord, free of coercion, can choose sides. Mariko, according to Toranaga's directions, disrupts Lady Ochiba's birthday party by demanding that Ishido allow Toranaga's people to obey his summons to join his procession to Osaka. He refuses. Citing the laws of tradition, Mariko ignores Ishido and the Council and attempts to escort Toranaga's ladies out of Osaka. They are prevented from leaving and Mariko declares she will commit seppuku at sunset. As a result, all the other ladies take Mariko's side because she was prevented from following the order of her liege lord.

The Council cannot allow Mariko to commit seppuku, so they publicly give in. Secretly, they plan to disarm Mariko and keep her at Osaka. To do this, Yabu opens a secret door for Ishido's ninja, but Blackthorne prevents them from disarming Mariko. During the battle, Mariko is killed. As Toranaga will later reflect, in this game of chess, he sacrificed his queen, "but Ishido lost two castles." The deed is done; the Council has to let everyone leave or Ishido will be admitting to murder. Proof that the alliance is weakening comes when Lord Kiyama's men provide a safe exit for Blackthorne. Blackthorne learns his ship has been burned and he races back to Yokohama.

War

Blackthorne, who thinks the Jesuits burned his ship, receives a note from Mariko telling him to build another. Some day he will learn that Toranaga burned Erasmus to neutralize the Jesuits. For betraying Mariko, Yabu is ordered to commit seppuku.

Mariko's sacrifice unlocks Osaka and disperses Ishido's alliance. It is now clear that Toranaga was never entirely defeated, and when Ishido comes out of Osaka to fight, Toranaga launches his battle plan. He wins and becomes Shōgun.
