Idols are typically expected to change careers after aging out of the industry, with female idols typically changing careers at age 25[1] and male idols at ages 30–45.[27] Because of their manufactured image and often fleeting careers, idols are generally not regarded as "serious" artists;[28] consequently, many young Japanese artists pursuing careers in acting or music reject the idol label in their bid to be seen as professionals.[29] Idols who leave a group are often given a farewell concert known as "graduations" (卒業, sotsugyō),[30] which originated from the idol group Onyanko Club, as the group's youthful concept drew similarities to an after-school club.[31] An idol having a "graduation" ceremony is seen more favorably than terminating a contract or voluntarily withdrawing, as the latter two terms are negatively connoted with scandals.[32]
