Held on the first Sunday of every month at Setagaya's homely Shoinjinja-dori shopping arcade, this market may be small but always features a nice range of sellers, dealing in everything from clothes and books to quirky decorative items and antique knickknacks. The clientele is tilted heavily towards families with small children, who also frequent the little cafés and food stalls lining the street. When visiting, make sure to check out Shoin Shrine, found at the north end of the arcade.
Note that the market will not be held in case of rain.
