The latest trend sweeping Japan involves the production and sale of unauthorized Disney-themed underwear, raising concerns over potential legal risks. Various manufacturers have started capitalizing on Japan's love for Disney characters by incorporating them into underwear designs. However, Disney, known for its stringent copyright regulations, has yet to respond to this unlicensed use of their brand. The timing of any possible action from Disney and potential copyright infringement penalties are still unknown.

Disney's characters are incredibly popular in Japan, ingrained deeply into the country's pop culture. In Japan, copyright issues are taken seriously, but the widespread love for Disney and the affordability of these unauthorized products has led to a boom in demand. The public's focus is on product enjoyment rather than potential legal implications

In the US or EU, such copyright infringements would likely be addressed promptly, with cease and desist notices or lawsuits. The public sentiment, while appreciative of affordable merchandise, is often more considerate of the legal implications of purchasing unauthorized merchandise.
