There has been a surge in counterfeit jerseys of Japan's national team recently. The fakes, often indistinguishable from the real deal, have been circulating the market in large numbers, duping numerous fans. The government is urging consumers to be extra careful when purchasing such merchandise, often marketed aggressively during the sports season.

Japanese consumers place a high value on authenticity and quality, and the impact of counterfeit merchandise on businesses and brand trust is a significant social concern. Additionally, Japan has robust intellectual property laws to protect original designs and penalize violators. This issue could affect the reputation of legitimate businesses as well as the national team.

Similarly to the US and EU, counterfeit merchandise is a serious issue. Authorities in these locations also strive to curb the circulation of fakes, supporting original manufacturers and protecting consumers from being swindled. However, the rate of such occurrences might be lower in the US and EU due to more rigorous enforcement of intellectual property laws and stricter punishments.
