The Japanese Kotatsu
One of the most beautiful and cozy things about Japanese winter life is the kotatsu. I'm sure this is something very foreign to most readers, so I thought I would expand on it today!
A kotatsu is a low, heated table — a small, efficient way of warming a space rather than heating an entire house. It is not unique to Japan (low heated tables also exist in Iran, Afghanistan, Spain, Portugal, and China), but the kotatsu holds a special place in Japanese family life that no other piece of furniture quite matches.
How Does a Kotatsu Work?
In the past, kotatsu were heated from underneath using charcoal. High-quality Japanese charcoal is virtually smoke-free, making it a surprisingly clean heating element. A low table was placed over a pit with heated charcoal in it — the original kotatsu. As modern life took over, these gave way to electric versions.
The modern kotatsu consists of a low wooden table frame, an electric heating element attached to the underside, a thick quilted blanket (called a futon in this context), and a separate tabletop placed over the blanket to hold it in place. The blanket traps the heat underneath, creating a warm cocoon for your legs and feet. You sit on the floor around the table, slide your lower body under the quilt, and experience one of life's simple pleasures.
The warming effects are even stronger when wearing a kimono — sitting at the table, a kimono can be loosened from the waist down and the warm air funnels up through the fabric, heating the wearer all the way to their neck.
The Center of Family Life
During the winter months, the kotatsu is the heart of the home. Meals are eaten at the kotatsu. Television is watched at the kotatsu. Naps are taken there (overnight sleeping not recommended, but definitely common). When guests come to visit, the saké is brought out and everyone sits together at the low heated table. Even cats and dogs are known to disappear under the quilted blanket and refuse to come out.
In The Daydreamer Detective Braves the Winter, each of the homes in the book has a kotatsu and they are used frequently. There are days when I really wish I had a kotatsu of my own. In the meantime, I will continue to visit Mei in the Miso Cozy Mysteries and enjoy good food with her and her family around this wonderful invention.
