The Sumida Coffee Festival 2026 Autumn will be held at Kinshi Park. Billed as one of the largest coffee festivals in East Tokyo, it will bring together 24 cafes and specialty coffee shops that roast their own beans, along with 15 bakeries and sweets shops. A limited number of pre-sale "Coffee Flight" tickets, which let you sample four different coffees, are also expected to be available, so it's worth keeping an eye out early. Admission is free, and you can easily enjoy the event with just a single cup of coffee or one sweet treat. For details and the latest updates, check the official Instagram account.
