One of my friend, Inge
who work in Japan said she need an article to plan her money.. and from google, I found Flea Market. ^^
Flea Market sell some used clothes, accessories, toys, shoes, books, potteries, pictures, and lots more. You might be able to find good souvenirs at good prices. Flea markets are held at parks, parking lots, department stores, shrines, temples, and so on. Many large flea markets are organized by associations like Japan Garage Sale Association (06-6362-6322), Japan Flea Market Association (06-6531-8417), Tokyo Recycle Campaign Citizen's Association (03-3384-6666), and Recycle Campaign Citizen's Association (03-3226-6800).
Most of the flea markets are held irregularly, so make sure to check schedules before you go. Also, flea markets aren't usually open when it rains.
