In ancient Japan, kitchens were an essential part of daily life. They incorporated a built-in warming drawer known as a 'kamado'. The kamado was a traditional clay stove used for cooking and keeping food warm. The Japanese believed that warm food was essential for good health and balance. The kitchen in ancient Japanese homes was typically located in a separate building, away from the living quarters. It was equipped with various cooking utensils, including pots, pans, and grills. The built-in warming drawer allowed the Japanese to enjoy hot meals throughout the day.
