Fermented Food Restaurant Koji

Fermented Food Restaurant Koji is a unique dining spot specializing in fermented cuisine, operated by fermentation researcher Yayoi Suzuki. At this rare restaurant, almost everything on the menu is made with homemade fermented foods. From enzyme drinks and main dishes to side dishes, fermented brown rice, and miso soup — even dessert is available for those who wish. Before opening the restaurant, Suzuki hosted numerous fermentation cooking classes and events. With experience teaching workshops on making homemade miso for parents and children, as well as serving as a university lecturer, she turned her passion into a one-of-a-kind restaurant. The restaurant’s signature Digestive Wellness Lunch changes monthly, offering a colorful selection of side dishes served on a beautifully arranged plate reminiscent of afternoon tea. Decorated with edible flowers, the meal is designed to engage all five senses. Each dish features meats, fish, or vegetables prepared with handmade fermented seasonings like salt koji and garlic koji. The vibrant presentation and rich flavors make the meal not only a feast for the palate but also a delight for the eyes — perfect for capturing a photo. One of the charms of dining at Koji is the opportunity to ask questions while enjoying your meal. Wondering, “What is this?” or “Can I make this at home?” The staff is more than happy to share their knowledge. Some guests have even reported feeling the effects of improved digestion within 30 minutes after enjoying the Digestive Wellness Lunch. If you're curious about fermented foods or simply want a delicious introduction to supporting your digestive health, Koji is worth a visit. Note: The restaurant is reservation-only, and bookings must be made at least 2 days in advance.
