A sticker art made by an artist known as 281 Antinuke, is seen on the back of a traffic signboard on a street in Tokyo November 26, 2013. With his face hidden behind sunglasses and a white surgical mask, the artist is almost as invisible as the radioactive contamination he is protesting against - yet his stickers are graphic reminders of the Fukushima nuclear disaster. Known as 281 Antinuke, Japan's answer to Banksy has covered Tokyo streets in images depicting politicians as vampires and children being shielded from radioactive rain to highlight the consequences of a meltdown at the Fukushima nuclear plant after an earthquake and tsunami on March 11, 2011.
