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 4 pm, 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 on the 4th Sunday. Stay in the loop for upcoming dates on their Facebook page.
