Kotatsu

One kotatsu is a traditional Japanese table with a built-in heat source and a blanket hanging over the frame to retain heat. Under the table there is usually an electric heater, while a thick blanket provides insulation and comfort for the legs. Kotatsu are mainly used in the colder months for eating, relaxing or sitting together in a warm and cozy setting. They combine a table with a heating system and are an important part of Japanese living culture.
