Uobei Shin-Okubo is a conveyor belt sushi restaurant on the third floor of a building across from Shin-Okubo Station in Tokyo. You pick aburi sushi, salmon, eel, and rolls, order on a tablet, and the sushi arrives at your seat on a rail. A Korean-language kiosk handles on-site reservations and orders, and booking through the app the day before keeps the weekend lunch wait under 10 minutes. Walking in without a reservation at weekend lunch means waiting with a large crowd.
