The 435-year-old Boroichi (rag market) takes place in Setagaya on December 15 and 16.
Boroichi is an enormous flea market at which more than 700 vendors sell a variety of used goods, antiques, handicrafts, and food to approximately 200,000 visitors. Any Cheapos looking to outfit their apartment, pick up an interesting Japanese knick-knack or just take some interesting photos should definitely take a look at this market.
The market will be running from 9 a.m. to 8 p.m. with closing usually marked by exploding firecrackers. The market is located next to Kamimachi Station on the quaint, light rail Setagaya Line. If you miss this one, there is another Boroichi (the first of the year) on the 15th and 16th of January.
