With just one day in Osaka, we toured the various neighborhoods and discovered that Osaka is the secondhand fashion capital of the world! Never have I seen so many re-sale shops with racks and shelves of designer goods all in pristine condition, available for a fraction of their original retail price. The Japanese are way ahead of the rest of us in this area. They take such good care of their items and have no negative stigma around buying designer goods secondhand. I can't recommend enough a stopover in Osaka for some secondhand shopping. Plus, they just opened Harry Potter World there too! Oh- and the Osaka Aquarium is an absolute must!
