The Ark Hills antique market is much classier compared to some of Tokyo’s usual fairs. In addition to the amazing finds you can usually dig up at a flea market like jewelry and home goods, you can also find stylish clothing brands, a great chance to update your wardrobe. Food trucks park here and there for the day, so you can hunt for cheapo deals all day! Or at least until 4pm, when it closes.
You can get to Ark Hills from Exit 3 of Roppongi-Itchome Station (Namboku Line).
This market happens about once a month, usually on the fourth Sunday. Stay in the loop for upcoming dates on their Facebook page.
