What is the Traditional Heater in Japan?
The traditional heater in Japan, known as the kotatsu, is a low table covered with a heavy blanket, under which a heat source is placed. It is a staple in many Japanese homes, providing warmth and comfort during the cold months. The kotatsu is cherished for its energy efficiency and ability to bring families together.
