I'm an editor for the main site; just trying to finally start posing in the forums more often.
It was actually Osaka; good eye though! I was visiting friends for a couple weeks and zipped around the country. I just snapped that pic off-the-cuff when I walked into an alley that looked like it would make a cool backdrop, and it did; you can't really tell with the cropped avatar version, but it turned out being one of those 1-in-1000 shots that you just can't stage.
