Good news if you are a cosplayer! And if you have a car. And if you need to renew your Japanese driver's licence.
You can legally pose for your licence while cosplaying. Granted, this isn't a mainstream trend by any means, but owning a "cosplay driver licence" is certainly possible in Japan, where they're also colloquially called "itai driver licence" (痛い免許証 or "itai menkyoshou"). In short, they're a regular licence, but with the driver wearing a costume.
It looks like colour contacts lenses are a-OK.
Ditto for cross-dressing as schoolgirl characters (above).
It's not only cosplayers who take advantage of Japan's lax rules for licence pics. Members of visual kei rock band Golden Bomber proudly showed off their driver's licence photos. One member even posed as a samurai, complete with topknot.
Due to obvious constraints, you can't see much of the cosplayer's costumes. However, there's something wonderfully subversive and nerdy about cosplaying in your driver's licence pic.
