It is called “KOTATSU”. In Japan, we use it in winter as a heating device.

Kotatsu is a low dining table covered with a blanket. On the reverse side of that table top is attached an electric heat source.

Japan has a lot of moisture because there is a rainy season. Most houses are made of wood, so we have to prevent it from molding. That means we need to build a drafty house. If we build a closed house as in western countries, it becomes moldy!

So Japan prefers local heating to general heating. Kotatsu is a representative of local heating.

They used to use artificial coal as a Kotatsu’s source of heat but it caused carbon monoxide intoxication. So now, electricity is used instead.

Kotatsu come in Horigotatsu and Okigotatsu versions. Horigotatsu is placed over a pit while Okigotatsu is put on that floor. These pictures show the latter one.

The former is very rare today because many people live in an apartment where we can’t dig a hole. So we often use the latter now.   ( This is Horigotatsu! ← )

 

We sit close in the Kotatsu and spend in a family way. It is a very humble life of Japanese choice.
But Kotatsu has a bad point. It makes people so lazy in winter, because if we
leave it, we feel very cold. Therefore we can't go out of it easily. Kotatsu helps us to get along with our family members. That's why we use it for long time.
