Step inside a bizarre Japanese 'Coming of Age' ceremony - featuring lots of booze and Mickey Mouse

LONDON - Every year, on the second Monday of January, young Japanese men and women don colourful kimonos and hakama to take part in "Seijin no Hi," or "Coming of Age Day," celebrations.

The event is a rite of passage for newly-classed adults that have turned 20 in the last year. In Japan, 20 is the legal age for drinking, smoking, and voting.

The get-ups are fabulous - reminiscent of Royal Ascot atire in Britain, including the iconically voluminous women's hats.

With attendants drinking legally for the first time, Coming of Age Day is normally a pretty raucous affair - police scuffled with revellers in Okinawa this year.
