The One Piece anime series has been on the air since 1999. So far, the show has aired a total of 20 seasons, but the structure of these seasons is very uneven, with seasons having as few as 14 episodes and as many as 118 episodes. Each season is centered on a specific narrative arc and thus follows the characters in a specific setting. But what about season 21 of One Piece? When (if) will it happen?
Season 21 of One Piece is certainly going to happen but we don’t know when. The show is currently in its 20th season, adapting the Wano Country arc, but we don’t know how many episodes it will have and when exactly it will end; as of November 14, 2021, 110 episodes of the 20th season have aired. Since this is not the last manga arc, One Piece will certainly be continued.
The rest of this article is going to bring you all the known and unknown information related to season 21 of One Piece. You’re going to find out about its potential release date, whether there is a trailer, what the story could be about, and much more about this great anime series.
One Piece Season 21 Release Date
Now, One Piece season 21 is certainly going to be released, that much is certain, but we don’t really know when. Namely, as we’ve said above, One Piece has a pretty uneven structure and release schedule, as you can see for yourselves:

| 13 | 422–456 | Impel Down | 35 | October 18, 2009 | July 11, 2010 |
| 14 | 457–516 | Marineford | 60 | July 18, 2010 | September 25, 2011 |
| 15 | 517–578 | Fishman Island | 62 | October 2, 2011 | December 23, 2012 |
| 16 | 579–628 | Punk Hazard | 50 | January 6, 2013 | January 12, 2014 |
| 17 | 629–746 | Dressrosa | 118 | January 19, 2014 | June 19, 2016 |
| 18 | 747–782 | Silver Mine, Zou, Marine Rookie | 36 | June 26, 2016 | April 2, 2017 |
| 19 | 783–889 | Whole Cake Island, Reverie | 107 | April 9, 2017 | June 30, 2019 |
| 20 | 890– | Wano Country | 109 | July 7, 2019 | present |
Now, seeing how the manga is not yet over and Oda plans to write more chapters, the anime will surely follow, which means that we are going to see season 21 of One Piece. When? We don’t know because of the uneven schedule, but we assume that it won’t be before Spring 2022, possibly even later. A lot later. Think 2023.

One Piece Season 21 Trailer
As you might have realized by yourselves, there is no trailer for the 21st season of One Piece simply because the season has not yet been announced.
One Piece will surely return, that you do not have to doubt, but until we actually get some info on the next manga arc, we won’t be getting any info on a new season, which is still ongoing and will run probably until the Wano Country arc is complete.
Taking into account all of the delays, we could wait until late 2022 or 2023 to get some info on the next arc.
One Piece Season 21 Plot
The plot of the anime series largely corresponds to that of the original manga. Differences can be seen in the introduction of the story, but also at the beginning in the point of the depicted violence. The first chapters of the manga are shown as a flashback when Luffy tells his first friend Zorro about why his straw hat is so important to him.
The test of whether Luffy is a pirate is limited to a joke that Luffy’s role model makes with him. A further change in the plot concerns the so-called filler episodes, which augment the actual plot with additional elements and adventures so that the television broadcast does not advance too quickly compared to the original manga.
Now, it would be impractical to explore the plot of each story arc, so we’re just going to tell you that the One Piece anime deals with the adventures of Monkey D. Luffy and his Straw Hat pirate crew as they are traveling around the world of pirates in search for the lost treasure of Gol D. Roger, a famous pirate.
Luffy wants to become the greatest pirate in the whole world and be the only person to locate Roger’s hidden treasure, the One Piece.
Now, each story arc explores a different segment of Luffy’s crew’s adventures. The current arc is the Wano Country arc, that is being adapted in the 20th season of the anime. As for what we can expect? Well, we don’t actually know.
One Piece is being adapted simultaneously with the manga, with fillers added when necessary. This means that the manga is not that much ahead and is also on the Wano Country arc. This, in turn, means that the plot of the next arc, and with it the next season of the anime, is still a mystery.
Which Story Arc Is Going to Be Adapted?
As we’ve said, the manga is also currently dealing with the Wano Country arc, so we don’t actually know which arc is going to be next. There is certainly going to be one, but its title, as well as its content, are a mystery at this moment. This means that we will have to wait and see what the manga has in store for us before we can see what the anime is going to adapt.
One Piece Season 21 Cast
The cast of One Piece changes every so often because each arc introduces some new characters but we also see some old characters return here and there. Now, the core of the series has remained the same and the characters’ voice actors are as follows:
| Character | Japanese | English (Funimation) |
|---|---|---|
| Monkey D. Luffy | Mayumi Tanaka | Colleen Clinkenbeard |
| Roronoa Zoro | Kazuya Nakai | Christopher R. Sabat |
| Nami | Akemi Okamura | Luci Christian |
| Usopp | Kappei Yamaguchi | Sonny Strait |
| Sanji | Hiroaki Hirata | Eric Vale |
| Tony Tony Chopper | Ikue Ōtani | Brina Palencia |
| Nico Robin | Yuriko Yamaguchi | Stephanie Young |
| Franky | Kazuki Yao | Patrick Seitz |
| Brook | Chō | Ian Sinclair |
| Jimbei | Daisuke Gōri and Katsuhisa Hōki | Daniel Baugh |
Now, we don’t know for sure, but we expect all of them to return to reprise their roles in the forthcoming season but we’ll have to wait a bit to make it official.
How Many Episodes Will There Be in One Piece Season 21?
It is now known how many episodes the 21st season will have. It can be anywhere from a dozen to more than a hundred and anything in between.
