There are several flea markets to be held on weekends in Tokyo. Some are very small, others are difficult to go in public transportation, the others are not kind to foreigners. From my experiences of visiting with my foreign friends, I will introduce 3 good flea markets in Tokyo.
Shinagawa Intercity Flea Market
Shinagawa Intercity Flea Market is held at the Shinagawa Intercity complex (near the JR Shinagawa station). It is very easy to access because it is in the center of Tokyo.
It is held inside and outside the building. Even on rainy days.
People who sell are many amateurs and many young people.
Clothes, potteries, accessories, handmade items etc are sold. Most of the secondhand items are in good conditions.
Where: Intercity Complex, Shinagawa (near Shinagawa Station )
When: Most Sundays: 10:00 AM – 4:00 PM (I recommend getting there before 2pm)
Access to the Flea Market: About 2 min walk from Shinagawa Station(JR).
Ohi Racecourse Flea Market
Ohi Racecourse Flea Market(大井競馬場, “Oikebajo Flea Market”) is the biggest flea markets in Tokyo.
It is held under the multistory parking lot area, so it is a bit dim.
The Ohi Racecourse Flea Market hosts more than 500 booths.There are various genres of shops.
Clothes, kimono, potteries, accessories, shoes, clocks, miscellaneous goods, handmade goods etc. The shopkeeper is from a professional to an amateur.
There is also some food stalls, so you can eat snacks around there.
