When and where it happens
The first official United States ONE PIECE Fest takes place August 25 and 26 at Cosm Los Angeles in Inglewood, California. Each date is divided into a 10 a.m.–2 p.m. session and a 4–8 p.m. session. The named venue and session structure matter because this is not an open-ended convention day with continuous general admission.
The programme repeats immersive dome presentations across the sessions and combines them with discussion and live music. Fans should use the time printed on their selected ticket rather than treating the two daily blocks as interchangeable access to the whole event.
What the programme contains
The owner schedule names English voice actors Ian Sinclair and Brina Palencia for discussions and brings ONE PIECE theme singer Hiroshi Kitadani to the live programme. That mix places English-language performance context beside music directly associated with the anime, while the dome format gives the event a presentation style distinct from a normal panel room.
A special guest is still teased without an identity. The programme does not support guessing who that person is, and a surprise appearance should not be treated as confirmed until the organizer names it or the event occurs. Session details can also change, so the live schedule remains the practical source.
The access limits
Lottery applications have closed. Selected buyers receive paired tickets that are described as non-transferable and tied to matching identification, which means the event is not a reliable walk-up option for fans who missed the lottery. The page does not establish a general resale or same-day admission route.
That restriction changes how the guide should be used: confirmed attendees can plan sessions, while other fans should monitor official coverage instead of travelling on an assumption of entry. The next useful updates are the teased guest’s identity, any programme change and owner-published recordings or recaps after the event.
