Tattoos are still taboo in modern Japanese society due to their historical association with criminal activity and rebellion, as well as their connection to religion and spirituality. The emphasis on conformity in Japanese culture also makes tattoos an unpopular choice for many. However, Westernization has led to greater acceptance among younger generations, and there is an underground tattoo culture that has gained popularity as a form of self-expression and rebellion against traditional values. It may take several decades before tattoos become truly mainstream in Japanese society.
