Fans have been hoping for news about One Piece season 2 ever since the first season ended with a rousing call-to-action, and while it won't be out for a good long while yet, Netflix has slowly been teasing more information about the One Piece follow-up.

The biggest news yet came from the streamers' annual Geeked Week, in September 2024, during which it gave a set tour (which you can see below) and revealed new casting information about characters joining the ensemble.

One Piece is a swashbuckling adventure series set in a fantasy world, about a young boy who sails the seas to find the 'One Piece' a mythical artifact which makes one the king of the pirates. With his band of friends, called the Straw Hats, he fights strange villains and traverses deadly lands in order to find it. A smash hit, One Piece quickly became popular as one of the best series on Netflix.

Season one of One Piece firmly cemented the Straw Hats as a band of friends and set our hero, Monkey D. Luffy, on his quest... now we just need to see where he goes. Here's everything we know about One Piece season 2 right now. 

One Piece season 2 potential release date

Our best guess for One Piece season 2 release date is June 2025. This comes from a report that suggested Netflix itself was eying this month for the return of the series, though it's not official confirmation from the streamer.

Tomorrow Studios' President, Becky Clements, previously suggested that due to the Hollywood strikes, filming and production on the series was delayed. Speaking to Variety in early September 2023, Clements said: "Realistically, hopefully, [One Piece season 2 is] a year away, if we move very quickly, and that is a possibility. Somewhere between a year and 18 months, we could be ready for air".

You can find the One Piece season 2 announcement video below, where Eiichiro Oda thanked viewers for tuning in via Transponder Snail and delivered the good news that we'd be setting sail with the Straw Hats once more.

In July 2024, Netflix confirmed that filming had officially started on the new season, which should give an idea of how long it'll take to come out.

One Piece season 2 trailer: has a trailer been revealed?

At the time of writing, no One Piece season 2 trailer has been revealed, but we've got the next best thing: a nice long look at the production.

Revealed at Netflix's Geeked Week in September 2024, this set tour shows us costumes, props, cast and crew for thes how, and there's also some concept art shown too.

What will One Piece season 2 be about?

Signs currently point to One Piece season 2 adapting the original series' Arabasta Saga. This story arc saw the Straw Hats finally venturing to the Grand Line for the first time and sees them being targeted by Baroque Works, the criminal syndicate who sent "Mr. 7" to try and recruit Zoro (who promptly cut the agent in half) at the start of season 1. 

The first season's final episode also included a couple of teases for what's to come. For one thing, we learned that two of Luffy's pirate foes, Captain Alvida and Buggy the Clown, have forged an alliance and are likely to seek revenge on the Straw Hats in the near future. 

Plus, the pre-credits teasers set up another villain from the universe. In that scene, we saw a man smoking two cigars burn a wanted poster of Monkey D. Luffy who we strongly suspect is none other than Captain Smoker. Smoker is a Marine Captain who has the power to turn his body into smoke, and he ruthlessly pursues pirates with his Devil Fruit abilities.

Thanks to the season 2 announcement video, we also suspect that Tony Tony Chopper will appear in the new season. For newcomers to the franchise, Chopper is an anthropomorphic reindeer doctor, and a fan-favorite character at that.

We'd expect the Straw Hat crew will be back on deck for One Piece season 2. That means we're hoping to see Iñaki Godoy reprise his role as the future King of the Pirates, Monkey D. Luffy, along with Mackenyu Arata as the expert swordsman, Roronoa Zoro, Jacob Romero Gibson as sharpshooter Usopp, Emily Rudd as the expert navigator, Nami, and Taz Skylar as their chivalrous chef, Sanji. 

And since Captain Alvida and Buggy the Clown have teamed up, we expect Ilia Isorelýs Paulino and Jeff Ward will return for season 2, along with Morgan Davies as Marine Vice Admiral Garp. 

Some new faces have been confirmed. One of these is Joe Manganiello (True Blood, Magic Mike) as Mr. 0, or Sir Crocodile, a former sea-faring warlord who works for Buggy in the anime. The other is Lera Abova (Anna, Pitch Perfect: Bumper in Berlin) as Nico Robin or Miss All Sunday, who in the anime is an archaeologist who comes to work for the Straw Hat Pirates.

What is The One Piece on Netflix?

Netflix clearly has One Piece fever. Along with giving One Piece season 2 the go-ahead, the streamer announced they are currently in production on a new anime adaptation of Eiichiro Oda's iconic story that will begin with the East Blue saga.

This adaptation will be known as The One Piece and will be 'distinct from the TV anime series that has captivated audiences for over 25 years', according to a Netflix statement.
