Imagine so many cosplayers and people to see them that busy Osaka streets are shut down completely in celebration of Japanese nerddom. That’s awesome.

This Sunday saw the 12th annual Nipponbashi Street Festa in Osaka, Japan. This year, like in the past, the streets are closed off for pedestrians. By that, I mean cosplayers, photographers, and those keen to absorb the festivities.

I went to the first Street Festa ages ago and each year, the event gets bigger and bigger.

Via Twitter, here are some of the best Street Festa cosplay and goings-on of this year.
