‘One Piece Fest’ Just Turned an 87-Foot Dome Into the Most Immersive Anime Experience Fans Have Ever Seen

‘One Piece‘ has spent nearly three decades building one of the most devoted fanbases in all of anime and manga, and Toei Animation is finally giving that fandom something to match its scale. After years of pop-up cafés and licensed attractions scattered across the globe, the franchise just landed its first-ever large-scale celebration built entirely around the fans themselves.

That celebration arrived this week in the form of ‘One Piece Fest,’ a two-day event held at Cosm Los Angeles on August 25 and 26. Marking the inaugural edition of what Toei is calling its “All One Piece” concept, the festival was designed to bring the world of Eiichiro Oda’s Straw Hat Crew to life in a way that hasn’t been attempted before in North America.

The festival’s headline draw is something fans are now calling one of the most striking anime experiences ever staged. Attendees have been sharing footage from inside Cosm’s massive 87-foot diameter LED dome, where a specially produced “Elbaph Experience” wraps a 5,000-square-foot, 12K by 10K display around the entire ceiling and walls, immersing guests directly in the world of the series’ newest story arc.

Fan reactions circulating online have captured just how overwhelming the experience felt in person, with attendees describing walking into what looks like an endless, swirling wall of ‘One Piece’ footage stretching in every direction. That kind of immersive scale is exactly what Cosm’s dome technology was built for, and pairing it with one of anime’s biggest properties has turned heads well beyond the festival’s ticketed attendees.

Beyond the dome, ‘One Piece Fest’ spans roughly 95,000 square feet of indoor and outdoor space, packed with recreations of locations pulled from the series’ 19 past story arcs, from its earliest East Blue days all the way through Elbaph. The event also features reimagined immersive environments, giant manga cover installations, a curated exhibition of props and costumes from the live-action adaptation, and live musical performances on an outdoor stage.

Access to the festival has been tightly controlled from the start. Only 7,000 fans total are being let in across the two days, split into four separate sessions of 1,750 attendees each, with tickets distributed through a lottery system that closed registration back in May. Winners were later given single-use passwords to purchase tickets in pairs, a setup that’s kept the event feeling genuinely exclusive rather than a typical open convention.

The timing of the festival lines up deliberately with One Piece Day, the franchise’s annual celebration marking the manga’s original 1997 debut in Weekly Shonen Jump. It also arrives while the anime’s Elbaph arc continues unfolding following the show’s return with new episodes back in April, giving Toei a clear opportunity to use the festival’s centerpiece attraction to reinforce excitement around the current storyline.

‘One Piece Fest’ fits into a broader pattern of the franchise expanding its physical footprint well beyond the page and screen. The property has already spawned pop-up cafés in cities like Las Vegas, and Netflix continues building out its live-action adaptation alongside a newly announced anime remake project in partnership with Wit Studio, signaling that Oda’s pirate saga is far from finished growing its presence across mediums.

For a franchise built on decades of serialized storytelling, watching fans get physically surrounded by that world inside a glowing dome feels like a genuinely new kind of milestone.
