Makuhari Messe Doki Doki Flea Market

There are flea markets, and then there's the eye-popping spectacle that unfolds at the Makuhari Messe conference centre every Golden Week. The Doki Doki Flea Market is Japan's largest bric-a-brac fair, drawing around 1,300 vendors each day. That's not all, though: the attractions also include a handicraft market, a sizable food hall and an appearance by idol supergroup AKB48 on Saturday (you can blame local radio station BayFM for that one).
