Idol culture refers to a phenomenon primarily found in East Asia, particularly in Japan and South Korea, where young performers, known as idols, are trained to entertain fans through music, dance, and various media appearances. These idols often cultivate a close relationship with their fans, who support them through merchandise purchases and attendance at events. The idol industry is characterized by rigorous training programs and a focus on image and branding. Idols are often marketed as role models, and their personal lives are closely followed by fans. This culture has led to the rise of popular groups like BTS and AKB48, which have garnered international acclaim.
