One Piece and Round1 Launch Their First Japan and US Simultaneous Collaboration on July 18

What was announced

The official One Piece site has announced a tie-up with the arcade and entertainment chain Round1, and the headline detail is timing. According to one-piece.com, the ROUND1 x ONE PIECE collaboration is the first between the two to run in Japan and North America at the same time, with the same period and the same concept in both regions. It starts on July 18, 2026 and runs through October 17, 2026.

Where and when

The campaign spans 159 locations in total. The official site lists 100 stores in Japan and 59 in North America, where Round1 operates its own arcades and entertainment centers. Because the two regions are running simultaneously, North American fans are set to get the same window rather than a delayed local rollout.

What the collaboration includes

The official rundown leans heavily on prizes and merchandise. Crane games will stock plush toys of Chopper in Round1 limited colorways, which one-piece.com bills as a world-first prize release for that particular plush design, alongside a standard Chopper plush and a Straw Hat crew mini-plush set. Figure lines include special versions of Luffy in his Gear 5 form.

Beyond the crane floor, the official site details apparel and goods available in-store and through online reservation, including T-shirts with four back designs, alphabet stickers, and acrylic blocks and stands. There is also a One Piece Card Game Round1 Promotion Pack of ten original cards, handed out one at a time with collaboration menu orders.

More than a merch drop

The collaboration is built to pull people into the stores themselves. Per the official listing, twelve locations host a stamp rally that trades three digital stamps for a postcard, with a bowling-score campaign offering a can badge. Six stores get large manga-panel photo spots, and three flagship locations, including DC Tokyo Plaza, Sendai Izumi, and Sennichimae, receive large wall decorations. Collaboration food and drink menus plus themed bowling and karaoke packages round out the in-store experience.
