The History of Kotatsu

Kotatsu: Japan’s Ultimate Winter Cozy Spot

The origins of the kotatsu date back to the Muromachi period (14th–16th century). At that time, people gathered around an irori, a sunken hearth, for warmth. Over time, they developed a way to trap heat by covering the hearth with a wooden frame and a blanket, creating the earliest form of the kotatsu.

By the Edo period (17th–19th century), the horigotatsu emerged, a version with a recessed floor where people could comfortably sit and place their legs. This design resembled modern kotatsu tables. Finally, the electric kotatsu that we know today became popular after World War II, offering an easy and convenient heating solution.

I enjoyed this type of Kotatsu at my grandparents house!
I loved reading books inside the Kotatsu. The red light was attractive.

Today’s kotatsu uses an electric heater mounted underneath the table. The heater warms the space within the kotatsu blanket, trapping heat and keeping everyone cozy.
