One Piece Sagas, Arcs, and Fillers List: A Simple Guide to the Anime

If you haven’t watched One Piece before, there’s a high chance you’ve at least considered it. It’s the highest-selling manga of all time, which means there must be something here that everybody seems to love, right? But then you discover the biggest barrier of entry to the series: 900+ episodes for the anime adaptation.

If reading manga is more of your thing, then you can always just read the source material. And that would skip any anime fillers at the same time! But that can be quite consuming as well: the manga has 970+ chapters that have been collected in 90+ volumes. It’s faster than watching the anime, but you’ll still be spending quite a lot of time chipping away.

There are plenty who prefer the anime so they can experience the story through animated action (and listen to the hype openings). Once you start watching and are in the weekly rhythm, then everything should be all good!

But if you’re a potential new fan or someone who took a break and have come back feeling a little lost, this ongoing series might seem a little intimidating. I am sure you need a little help to get things started: Here is a handy list of the One Piece Sagas and Arcs, with all the story and fillers properly acknowledged.

Most fans commonly divide the story up into arcs (most of which are named after islands or locations), the sagas that encompass them, and lastly into two halves of the series (set before and after a two-year time skip), but not everybody separates them in this manner. 

TOEI has its own method of dividing the series into ‘seasons’, while Funimation compiles the series into much longer and therefore fewer seasons. We’ll be using the most common format, and include some descriptions to narrow it down to where you decide to watch One Piece.

The First Half

  • Sea of Survival: Super Rookies Saga

One Piece

The first half of One Piece is separated into six sagas:

  • East Blue Saga
  • Arabasta
  • Sky Island
  • Water 7
  • Thriller Bark
  • Summit War

East Blue Saga

Its intro saga is the East Blue Saga, named after one of the major oceans in the world. The East Blue Saga is divided into the following arcs:

  • Romance Dawn Arc
    • Chapters 1-7 (Volume 1)
    • Episodes 1-3
  • Orange Town Arc
    • Chapters 8-21 (Volumes 1-3)
    • Episodes 4-8
  • Syrup Village Arc
    • Chapters 22-41 (Volumes 3-5)
    • Episodes 9-18
  • Baratie Arc
    • Chapters 42-68 (Volumes 5-8)
    • Episodes 19-30

  • Loguetown Arc
    • Chapters 96-100 (Volumes 11-12)

    • Covers of Chapters 35-75 (Volumes 4-7)
    • Episodes 46-47
  • Warship Island Arc (Filler)
    • Episodes 54-61

The saga has to do with the reason so many pirates have set sail in search of the One Piece. It also introduces Monkey D. Luffy and the start of him building his own crew. He meets and recruits four of his crewmates: including Zoro the swordsman, Usopp the gunner, Nami the navigator, and Sanji the cook. The Warship Island arc is the only filler.

Alabasta Saga

Following this is the ‘Alabasta Saga’, named after the country that the Straw Hats are trying to reach. The Alabasta Saga is divided into the following arcs:

  • Reverse Mountain Arc
    • Chapters 101-105 (Volume 12)

  • Post-Alabasta Arc (Filler)
    • Episodes 131-135

In the Alabasta Saga the Straw Hat Pirates meet and pledge to help the princess of Alabasta make it home, to avert a disastrous plan by the nefarious Baroque Works. Tony Tony Chopper joins the crew as a doctor, while Nico Robin joins as an archaeologist. The only filler arc in this saga is the Post-Alabasta Arc.

Sky Island Saga

‘Sky Island Saga’ is the name of the third one, referring to the legendary floating island known as Skypiea. The Sky Island Saga is divided into the following arcs:

  • Goat Island Arc (Filler)
    • Episodes 136-138

The Sky Island Saga follows the crew as they research the truth behind the legend of the floating island. Once they manage to make it there, they discover a plot that could destroy it. Events elsewhere introduce two members of the World Government-affiliated Shichibukai: Bartholomew Kuma and Donquixote Doflamingo. The Goat Island Arc, Ruluka Island Arc, and G-8 Arc are all fillers in this saga.

    • Episodes 313-325

Some of the major developments in this saga include the joining of Franky the shipwright and the replacement of their ship, the Going Merry, with Thousand Sunny. The filler arcs within this saga are the Ocean’s Dream Arc and Foxy’s Return Arc.

Thriller Bark Saga

The penultimate saga in the first half is the ‘Thriller Bark Saga’, named after the island turned ship that the majority of the saga takes place in. The Thriller Bark Saga is divided into the following arcs:

    • Episodes 326-335
  • Chopper Man Special
    • Episode 336
  • Thriller Bark Arc
    • Chapters 442-489 (Volumes 46-50)
    • Episodes 337-381
  • Spa Island Arc (filler)
    • Episodes 382-384

A contrasting saga from the others. It focuses on the crew’s arrival on a ghost island. It’s within this saga that the crew meets Brook and welcomes him as their musician. The Thriller Bark arc is the only canon arc in the saga, with both the Ice Hunter Arc and Spa Island Arc acting as filler.

Summit War Saga

The final saga for the first half is the ‘Summit War Saga’, which is the lead-up to a large scale war that changes the world forever. The Summit War Saga is split up into these final arcs:

    • Episodes 490-491, 493-516

    • Episode 492

Certainly, one of the most intense arcs as Luffy and crew are caught in the middle of an erupting war between the Whitebeard Pirates and the World Government. Even as the final saga of this half, we’re still introduced to new fan-favorite characters such as Trafalgar Law. It ends with Luffy and his crewmates deciding to train themselves in preparation for traveling to the New World. The only filler arc within this saga is the Little East Blue Arc.

The Second Half

Where to Watch One Piece

If you’re interested in watching the anime then you have a couple of options: The first is to watch the series on Crunchyroll with the Japanese dub. For the most part, Crunchyroll splits it up by the common way listed in this article. The first half is divided into each saga, while the second half is so far split up by its smaller arcs.

Another option you have is to watch it on Funimation, which has the Japanese dub, and up to Season 9 or the Fish-Man Island Saga dubbed in English as well (the English dub does require a subscription for most episodes though).

Finally, if you’re still not interested in watching the anime and think you’d much rather read through the series, you’re in luck! The entire series can be read on VIZ.
