Oden (おでん) is a cherished Japanese hot pot dish, especially popular during the colder months. This comforting stew features a variety of ingredients such as daikon radish, boiled eggs, fish cakes, konnyaku (a chewy yam cake), and tofu, all simmered in a flavorful soy-based dashi broth. The origins of oden trace back to the Muromachi period (14th century), evolving from a simple grilled tofu dish into the simmered stew enjoyed today .
