Started by Japanese model Naoko Yokochi after studying nutrition science and becoming a qualified food sanitation expert, Potasta serves up traditional, exotic and artful sandwiches. This on-the-run sandwich stand started as a pop-up, but after selling out consistently in 15 minutes and cries from the loving locals, Potasta became an evergreen food stand in the popular residential area of Yoyogi Uehara. On your visit, we recommend indulging in a local favorite like the Green Curry Carrot Sandwich or the Scrambled Egg and Vegetable Sandwich, though they do have tasty traditionals (ham and cheese) and a few sweet yet sugarless options (Sweet Potato or Kinako sandwiches) as well. Whatever your pick, the biggest challenge is waiting in line and picking one of the artfully displayed morsels stuffed with locally sourced vegetables and proteins of your choice.
