The eighth annual Nipponbashi Street Festa stamped Osaka March 20, 2012 (Nipponbashi is Osaka’s geek district – much like Akihabara is for Tokyo). Cosplayers turned up in colourful outfits, dressing as characters from their favourite manga, anime, and video games. The street was closed to cars, and otaku flooded the streets, snapping pics, cosplaying, and hanging out.

Travelling Indian performers, who earn a meagre income from putting on shows on the streets, often scout areas to gather a large street audience who then give money on a collection plate at the end of the show.
