Ghana chocolate x One Piece collab

Lotte’s Ghana chocolate campaign has paired with *One Piece* again for Mother’s Day in Japan, turning a seasonal candy promotion into a heavily shared anime tie-in. (lotte.co.jp) The 2026 campaign began on March 24, with six Mother’s Day visuals built around three family pairings from the series: Robin and Olvia, Chopper and Dr. Kureha, and Sanji and Sora. Each pairing appears in two versions, one framed as a child’s message and one as a parent’s message. (one-piece.com) Lotte’s campaign site says Japan’s Mother’s Day falls on May 10 this year and Father’s Day on June 21, and the company is using both dates for a broader “say thank you with Ghana” push. The site also lists an April 1 to April 14 repost giveaway tied to the brand’s official X account. (lotte.co.jp) The promotion is not just social media art. Lotte started selling a Ghana Chocolate Selection Gift Box on April 7 at noon through its online shop, priced at 3,980 yen, with 11 varieties across 12 items and two *One Piece* Mother’s Day stickers per box. (lotte.co.jp) Lotte capped that gift box run at 1,500 sets, which helps explain why the campaign is being treated as both a fandom collectible and a holiday gift. The official *One Piece* site says the box is exclusive to the Lotte online shop. (lotte.co.jp, one-piece.com) This is the second straight year of the Ghana x *One Piece* family-day campaign. The official *One Piece* site said on March 24 that the 2026 project follows last year’s collaboration and will add Father’s Day visuals later in April. (one-piece.com) The creative hook is family rather than action. The campaign materials center on parent-child bonds from the story, and Lotte’s site says Ghana Milk and Premium Ghana packages now include a message space on the back for handwritten notes. (one-piece.com, lotte.co.jp) That makes the collaboration a clean fit for a long-running Japanese seasonal marketing pattern: brands wrap Valentine’s Day, Mother’s Day, and Father’s Day gifts in character art, then use limited extras and repost lotteries to widen reach. In this case, the extra incentive is *One Piece*, one of Japan’s biggest anime properties, attached to a mass-market chocolate brand with national retail distribution. (lotte.co.jp, one-piece.com) The next beat is already scheduled. Lotte and *One Piece* say new Father’s Day visuals are due in late April, keeping the campaign alive after the Mother’s Day push peaks. (lotte.co.jp, one-piece.com)
