Tokyo Nomi no Ichi (Flea Market) 2019

Held twice a year (in spring and fall) and gaining a strong following, this antique fair takes place at the Tokyo Oval Keiokaku right next to the train station.
Since this is an outdoor market they do sometimes cancel in case of rain, and will announce at 7am on the day via their website. Entry is ¥500 but free for elementary school students and the market will be open from 9am to sunset.
Note that the November, 2019 edition will take place at Showa Kinen Park.
