Buying Used Stuff in Japan: Meiji Flea Market
Apartments are tiny here, though. All that old stuff piles up. There are a few ways to get rid of it: throw it out (my city garbage collection also picks up reusable clothes and furniture), take it to a second-hand shop (and get almost nothing for it - sometimes you have to pay them!), or sell it at a flea market.
Things to look for in the pictures above: twin cameras, Winnie the Pooh, a wig, too many scissors, brand new sunglasses, a collection of desk lamps, pressure, a spoon set, a boot and a heel, three dogs in a row, and a handheld game system.
There is a Japanese-language website which has an up-to-date list of flea markets, with upcoming dates, times, number of stalls, and organizers. Some are held quite sporadically. If you really want to bring a lot of Japanese stuff home, you have time to browse, and you're in Japan at the right time, flea markets can be a great source of souvenirs and clothes - just be sure you pay attention to Japanese size differences!
