Wano Country Arc: Complete Analysis of One Piece’s Masterpiece

Article written by the Wanted Store team — sources: One Piece manga vols. 91–105, Toei Animation anime. Updated on April 26, 2026. Major spoilers.

What Is the Wano Arc?

The Wano arc (or “Wano Country”, Wano Kuni) is the tenth major arc of the Yonko Saga in One Piece. Covering volumes 91 to 105 of Eiichiro Oda’s manga — chapters 909 to 1057 — it spans nearly four years of publication (from July 2018 to August 2022). It is officially the longest arc in the entire series, surpassing Dressrosa in both chapter count and narrative density.

Wano is not a simple adventure arc: it is the culmination of more than twenty years of storytelling. It features the fall of two Emperors, the central revelation about Luffy’s Devil Fruit, the full return of the Worst Generation, and the conclusion of a twenty-year family vendetta carried by the Kozuki clan. Many readers and critics consider Wano to be the absolute masterpiece of One Piece, standing at the crossroads of samurai epic, classic shōnen, and myth.

Wano Before the Straw Hats’ Arrival

Wano Country is a closed land, deliberately isolated from the rest of the world, heavily inspired by Edo-period Japan. When the Straw Hats arrive, the country is living under a dual tyranny:

• Kaido of the Hundred Beasts, one of the Four Emperors (Yonko), who exploits Wano as a giant weapons factory using rivers polluted by the SMILE factories.
• Kurozumi Orochi, the corrupt Shogun and political puppet who usurped power twenty years earlier by assassinating Kozuki Oden, the rightful daimyo of Kuri.

The arc’s central flashback (vols. 96–97) recounts the life of Kozuki Oden, a friend of Gol D. Roger and Whitebeard (Edward Newgate), publicly executed by Kaido after an hour of agony in a cauldron of boiling oil. Before dying, Oden entrusts a mission to his nine loyal samurai — the Nine Red Scabbards (Akazaya Nine) — to open Wano to the world and avenge his death twenty years later.

This story-within-a-story structure gives Wano an emotional depth that is rare in shōnen, transforming each subsequent battle into an act of remembrance.

The 3 Major Phases of the Arc

Act 1: Infiltration and Planning

The Straw Hat crew arrives in Wano Country in scattered pieces. Each member adopts a Japanese alias (Luffy becomes Luffytaro, Zoro becomes Zorojuro, Sanji becomes Sangoro). Trafalgar D. Water Law, already on the ground, lays out the plan devised with Kin’emon: trigger a coordinated uprising on the night of the Fire Festival at Onigashima, to take out Orochi and Kaido in one fell swoop.

This act introduces the key figures of the land — Otama, Kiku, Hiyori, Tonoyasu — and reveals the full extent of the misery imposed on the people. Luffy is quickly captured and sent to the Udon Prison Mine, where he will meet Hyogoro the Flower.

Act 2: Preparing the Raid

Act 2 centres on the Udon Prison Mine. It is there that Hyogoro, a former yakuza boss from Wano’s golden age, teaches Luffy the basics of advanced Haki, particularly the use of Ryuo (Flowing Haki at a distance) — an ability essential for damaging Kaido. Meanwhile, Kin’emon recruits surviving samurai, Kid and Killer escape, and the alliance takes shape: Straw Hats + Heart Pirates + Kid Pirates + Mink Tribe of Zou + Wano samurai.

This act concludes with Kanjuro’s betrayal and the kidnapping of Momonosuke, a reversal that puts the entire raid on a knife’s edge.

Act 3: The Battle of Onigashima

Act 3 is the longest and most spectacular. It spans nearly 150 chapters and takes place almost entirely on the fortress island of Onigashima. The pirate-samurai alliance attacks by sea during the banquet, Big Mom arrives to reinforce Kaido, and the battle fragments into multiple parallel duels throughout the castle: the roof (Yonko vs. alliance), the floors (Tobi Roppo vs. Straw Hats/Minks), the lower levels (guards vs. Akazaya Nine).

Key Battles

Each battle serves a theme: Zoro definitively liberates Wano by defeating Kaido’s right hand, Sanji finally accepts his Vinsmoke heritage, and the Law/Kid duo proves that the Worst Generation can defeat an Emperor as a team.

The Awakening of Gear 5 — The Hito Hito no Mi Model Nika Revelation

The narrative climax of Wano arrives at chapters 1043–1044. Defeated once again by Kaido on the Skull Dome’s roof, Luffy appears dead. His heart stops beating. And it is precisely at that moment that the Drums of Liberation resound — those of the Sun God Nika.

Revelation: Luffy’s fruit was never an ordinary Paramecia called the “Gomu Gomu no Mi.” It is in reality the Hito Hito no Mi, Model: Nika, an extraordinarily rare mythical Zoan that the World Government had been trying to conceal for centuries. This fruit grants its user the power of the “Warrior of Liberation”, capable of reshaping reality like a rubber cartoon.

The awakening manifests as Gear 5: white hair, red-rimmed eyes, a shining white body, and all-powerful imagination. Luffy stretches the ground like a trampoline, turns lightning into rope, and inflates his body to the size of the castle. Kaido himself acknowledges it as the most entertaining fight of his life. For more on this revelation, read our feature: The True Gomu Gomu no Mi: Hito Hito no Mi Model Nika.

The scope of this revelation is immense: it links Luffy to Joy Boy, to the Void Century, and explains why the World Government has always considered him an existential threat. Wano is no longer just the liberation of a country — it is the awakening of a myth.

Post-Wano Consequences

The arc’s conclusion permanently reshapes the balance of the One Piece world:

• Luffy is promoted to the 5th Emperor (Yonko) with a bounty of 3 billion Berries, alongside Shanks, Blackbeard, Buggy the Clown, and Edward Weeble.
• Kaido and Big Mom fall simultaneously — unprecedented: for the first time in recent history, two Emperors are taken out in a single battle.
• Buggy the Clown is promoted to Yonko in a purely administrative fashion, which delighted the entire fandom.
• The Cross Guild emerges: Buggy the Clown, Sir Crocodile and Dracule Mihawk found a rival organisation that places bounties on Marines.
• Wano Country remains closed but Momonosuke, now an adult Shogun, vows to open the country “when the time is right” — that is, when the Will of D. has completed its mission.
• Kozuki Oden is avenged twenty years after his execution, fulfilling the prophecy he left behind.

Why Is Wano Considered the Best Arc?

Three main reasons recur in both English-language and international criticism:

1. Multi-layered writing. Wano weaves together several timelines (the raid’s present, the Oden flashback, Kaido’s past, the future prophesied by Toki). Oda draws together dozens of narrative threads left open for hundreds of chapters: the Kozuki lineage, the Road Poneglyph, the true nature of the Gomu Gomu no Mi, Yamato’s destiny.

2. Toei Animation at its peak. The episodes covering the Luffy vs. Kaido battle — particularly episodes 1015 (“I’m Luffy, the Man Who Will Become King of the Pirates”), 1062, and 1071 (Gear 5 revelation) — feature in every ranking of the best shōnen animation episodes of the decade.

3. Unmatched emotional depth. From Oden’s sacrifice to Yamato’s farewell, from Hiyori playing the shamisen for Kawamatsu to Luffy’s apparent death before his awakening, Wano multiplies pivotal emotional moments. It is the arc that brought the most readers to tears since Marineford.

FAQ — Frequently Asked Questions About the Wano Arc

How many volumes does the Wano arc span?
The arc spans 15 volumes, from volumes 91 to 105 inclusive, covering roughly 150 chapters. It is officially the longest arc in One Piece to date.

Which anime episodes correspond to the Wano arc?
The Wano arc begins at episode 892 and concludes at episode 1085 of the Toei Animation anime, covering nearly 200 episodes.

Who dies in the Wano arc?
On the antagonists’ side: Kurozumi Orochi (killed by Kaido, then truly finished off), Kanjuro, Kaido and Big Mom (Charlotte Linlin) (defeated but likely survivors). On the allies’ side, unlike Marineford, no major character dies — Wano is an arc of victory, not mourning.

Is Gear 5 Luffy’s strongest power?
Yes. Gear 5 is the awakening of his mythical Zoan Devil Fruit, the Hito Hito no Mi, Model: Nika. It surpasses all previous Gears in power, but consumes enormous energy and remains duration-limited until Luffy fully masters the transformation.

Does Yamato join the Straw Hat crew?
No. Despite her wish to set sail, Yamato ultimately chooses to remain in Wano Country to explore the land as Oden — her role model — had done. She may join the crew later in the series.

Who is Joy Boy and what is the connection with Luffy?
Joy Boy is a legendary figure from the Void Century, regarded as the first incarnation of the Sun God Nika. The awakening of Gear 5 makes Luffy Joy Boy’s direct successor, prophesied by Zunesha and awaited for 800 years.

Why does Big Mom intervene in Wano Country?
Initially an adversary, Big Mom (Charlotte Linlin) forms a temporary alliance with Kaido to conquer the world. She is defeated by the Law/Kid tandem, who plunge her into the magma beneath Onigashima.

Does Wano mark the end of One Piece?
No. Wano marks the end of the Yonko Saga and the entry into the Final Saga, opened by the Egghead arc. Oda has confirmed that the series is approaching its conclusion, but that several major arcs remain before the “One Piece” itself.
