An idol is a type of entertainer marketed for image, attractiveness, and personality in Japanese pop culture. Idols are primarily singers with training in other performance skills such as acting, dancing, and modeling. Idols are commercialized through merchandise and endorsements by talent agencies, while maintaining a parasocial relationship with a financially loyal consumer fan base.
