Japanese adults vent dark obsession with young girls at 'little idols' concerts

In a cramped and dark venue in a sleazy Tokyo district, dozens of middle-aged men cheer at a performer on stage: The object of their adoration is a 6-year-old girl. Decked out in makeup with ribbons in her hair, Ai is dressed like an adult but still looks very much a child. Even though Ai is so young, she is technically considered an "idol" singer. More typically, idols are in their teens. The idol phenomenon is common in Japan, where rights groups have complained that society's sometimes permissive view of the sexualization of young girls puts minors at risk.
