What is kotatsu?

A kotatsu is a traditional Japanese heating device commonly found in Japanese homes during the colder months. It consists of a low, wooden table frame covered with a heavy blanket or futon, with an electric heater underneath. The table top is typically removable or has a small cutout in the center where a heat source can be placed.

To use a kotatsu, one has to sit on the floor and place their legs underneath the blanket, effectively trapping the heat generated by the heater in a cozy space. The warm air circulates within the blanket, providing a comfortable and warm environment. It is a popular way for families or friends to gather and stay warm together during winter.

Kotatsu originated in ancient Japan during the Muromachi period (14th-16th centuries) and were initially used exclusively by the higher classes. However, over time, they became more accessible to all social classes, and now they are commonly used in many Japanese households.

Apart from being a source of warmth, kotatsu also serves as a versatile piece of furniture. When not in use as a heating device, the blanket and heater can be removed, allowing the table to be used for other purposes like dining or working.

In recent years, modern variations of kotatsu have emerged, incorporating features such as adjustable temperature settings and built-in storage space. Some even come with floor chairs or cushions specifically designed for a more comfortable kotatsu experience.

Overall, kotatsu is not just a practical heating solution but also a symbol of comfort and togetherness in Japanese culture during the colder seasons.
