Shōgun · A Viewer's Companion
The hard part of Shōgun isn't the bloodline — it's that surnames come first (Toda Mariko is Lady Mariko of clan Toda), titles replace names mid-scene, and half the cast is lying about whose side they're on. So this chart is part family tree, part allegiance map: indigo borders serve Lord Toranaga, crimson is Ishido and the Osaka court around the child Heir, and grey marks the in-betweens still selling their loyalty to the highest bidder.
Five facts on this map explain nearly every scene of political maneuvering — and the finale.
Mariko was born Akechi — her father, Akechi Jinsai, assassinated his own liege, the tyrant Kuroda, and his entire family was executed for it. Mariko alone was ordered to live with the disgrace. That’s why she petitions for death every year, why her marriage is a cage, and why the dashed line on the chart reads “the name she carries.” Her husband’s name, Toda, is the mask over the wound.
The dying Taikō, unable to leave the realm to a child, appointed five regents to rule until his son Yaechiyo comes of age. The show opens with the other four — Ishido, Kiyama, Ohno, Sugiyama — uniting to impeach the fifth: Toranaga. The catch: impeachment needs a full Council vote, so every death and resignation on this chart is really a move in that arithmetic.
Ochiba no Kata is the Taikō’s consort and the Heir’s mother — and the true will behind Ishido. Here’s the twist the show saves for late: the tyrant Mariko’s father killed was Ochiba’s father. The two women were childhood friends standing on opposite sides of the same murder — which is why Mariko’s final act in Osaka can move Ochiba when no army could.
Anjin simply means pilot — it’s what everyone calls Blackthorne because his real name defeats Japanese phonetics. When Toranaga makes him hatamoto, he’s granting him rank as a direct retainer — with a fief, a stipend, and a household run by his assigned consort Fuji, who serves while grieving the husband and infant son Ishido’s politics cost her in episode one.
Kashigi Yabushige holds Izu for Toranaga while secretly courting Ishido — then swears to whichever side is winning that scene. He’s the show’s dark-comic heart, and his nephew Omi is quietly learning the family trade. His Season 1 ledger finally comes due on a cliff above the sea, with one last question for his lord.
All season, Toranaga’s men whisper about Crimson Sky — a suicidal all-out assault on Osaka. The finale reveals the trick: the plan was Mariko. Sending one woman with an untouchable name into Osaka forced Ishido to either free his hostages or disgrace himself — and split Ochiba from his cause. The chart’s quietest card wins the war.
Family name first, given name second, titles everywhere — and the show almost never stops to help. Keep these straight:
Yoshii Toranaga is Toranaga of clan Yoshii; Toda Mariko is Mariko of clan Toda — her husband’s clan. She was born Akechi Mariko, and that difference is the engine of her whole story.
Buntaro (formally Toda Hirokatsu) is her husband — brooding, brutal, a master archer. Blackthorne is the shipwrecked English pilot she translates for. One line on the chart is gold and solid; the other is gold and dashed.
Both scheming, both named Kashigi. Yabushige (Tadanobu Asano) is the older lord of Izu with the rat-trap grin; Omi is his young nephew who runs the fishing village of Ajiro where Blackthorne washes ashore.
Ishido — the general who holds Osaka Castle; the main rival. Kiyama and Ohno — Christian lords voting with the Church; Ohno is the one veiled by leprosy. Sugiyama — the high-born one, murdered when he blocks Ishido’s plans.
Taikō was the dead ruler Nakamura’s title — a commoner who rose to rule but could never be shōgun. Shōgun is the military dictatorship everyone suspects Toranaga of wanting — the accusation he denies for ten straight episodes.
Father and son, both Toda, both serving Toranaga. Hiromatsu is the grizzled old general with the sword always half-drawn; Buntaro is his son — and Mariko’s husband.
John Blackthorne = the Anjin (“pilot”) = hatamoto. Same Englishman: his name, his nickname, and his rank. When a character says any of the three, they mean Cosmo Jarvis.

The Jesuit who translates for the powerful — fluent, devout, and torn: Toranaga’s trusted interpreter, the Church’s instrument, and Blackthorne’s natural enemy.

The salty Spanish pilot sailing for the Portuguese — saves Blackthorne’s life, calls him “Ingeles,” and would still sink him for the Black Ship’s profits.
A note on the portraits: these are the characters as they appear on screen — stills from the Shōgun wiki, cropped and served from this site so nothing loads from anyone else’s servers. Only the Taikō, glimpsed just briefly in flashback, appears as his title in kanji (太閤). Chart reflects the story through the end of Season 1 of the 2024 FX series — spoilers to there, including the finale.
