Ancient Japanese kitchens, known as kamado, were typically small and focused on simplicity. These kitchens featured charcoal stoves, clay pots, and bamboo utensils. To enhance the ambiance of an ancient Japanese kitchen, glass pendant lights can be installed. These lights would provide a soft and warm illumination, creating a cozy and inviting atmosphere for cooking and dining. The minimalist design of the glass pendants would complement the simplicity and elegance of the traditional Japanese kitchen.
