Japan emperor's daughter Aiko turns 20, throne not in sight

Japanese Princess Aiko, the daughter of Emperor Naruhito, on Wednesday turned 20, ready for a debut as a new adult member to take a share of official duties for the royal family whose population continues to shrink under the male-only succession law. Currently studying Japanese literature at Gakushuin University, Aiko says she is willing to help her parents by participating in royal duties.
