Japan has a long history of making fermented foods, such as miso, soy sauce and sake. Fermented foods are essential ingredients in the dietary habits of Japanese people. In the past, it wasn't easy to locate enough ingredients to sustain a healthy diet due to the lack of nutrient-dense foods. When Koso was created, it provided many different types of essential nutrients, allowing people to improve their quality of life.
