The Japan national football team is providing special collaboration flags for fans as part of their preparations for the 2026 FIFA World Cup. These flags are a collaboration with the popular manga 'ONE PIECE' and are being distributed at the 'SAMURAI BLUE Festival' held at MIYASHITA PARK in Shibuya. The Japan national team issued a warning on their official X account, stating that strict penalties will be enforced if reselling activities are discovered. The event runs from the 11th to the 28th, with flags being given to the first 200 people each day. The national team aims to ensure that fans can receive the items fairly and has prohibited reselling. This policy is intended to avoid confusion among fans. Through the message against reselling, the team is asking fans to act responsibly.
