Usukuchi is a type of soy sauce that originates from Japan. It is lighter in color and flavor compared to regular soy sauce, making it ideal for dishes where a subtle taste is desired. Usukuchi is often used in cooking to enhance the natural flavors of ingredients without overpowering them. This soy sauce is particularly popular in the Kanto region of Japan. It is commonly used in soups, marinades, and dressings, providing a delicate umami flavor. Usukuchi is also known for its slightly sweeter taste, which can complement various Japanese dishes, including sushi and sashimi.
