To some degree, the sexualization of young girls is mainstream in Japan. For example, Japan’s most popular and mega-profitable all-female pop group AKB48 includes members as young as 13; and they’ve posed for ++sexy & semi-nude layouts in Japan’s Weekly Playboy several times.
The AKB48 members are bound by their contracts to remain celibate while working for the parent company that manages the group, but they often appear in lurid commercials and videos depicting the band members exchanging kisses and singing sexually suggestive lyrics.
The "no dating" clause of the contracts has resulted in some idols being sued for breaking it, accused of damaging their reputations. Two years ago Minami Minegishi from popular girl band AKB48 shaved her head and wept in apology, after breaking management firm rules by spending a night with her boyfriend.
