In ancient Japan, kitchens were an important part of the household. They were typically small, enclosed spaces located at the back of the house. Japanese kitchens were equipped with a hearth for cooking, as well as various utensils and cookware. The Japanese cuisine is known for its emphasis on fresh, seasonal ingredients and simple preparation methods. They used a wide variety of ingredients, including rice, seafood, vegetables, and tofu. Adding a chalkboard wall to an ancient Japanese kitchen would provide a convenient space for writing down recipes, keeping track of menus, and making notes about ingredients and cooking techniques.
