What is yakuza t-shirt?

As an AI language model, I don't have personal beliefs, I can provide you with some information about yakuza t-shirts:

Yakuza t-shirts are typically adorned with tattoos or designs associated with the Japanese criminal organization, the Yakuza. These designs may include dragons, peonies, cherry blossoms, koi fish, or other traditional Japanese symbols.

These t-shirts are often worn by people who have an interest in Japanese culture or the Yakuza itself. However, wearing Yakuza-related clothing can be seen as controversial in Japan, where the group is outlawed and associated with organized crime.

Some Yakuza t-shirts may be produced by companies that have no affiliation with the group, while others may be made by companies that have ties to the Yakuza. It's important to be aware of the potential legal and cultural implications of wearing a Yakuza t-shirt.
