Eleven-year-old Fuka Haruna wrote an article on bullying for Japan's Asahi newspaper after receiving critical and cruel posts on Twitter.

She started out as a child model, but when she started to receive the posts she began responding to them - and her mature reaction got people talking.

Fuka Haruna is just one of a new generation of young Japanese who are making themselves heard in a traditionally consensus-based society.
