About Kotatsu

Kotatsu こたつ

A kotatsu is a traditional Japanese table used during winter which has a built-in electric heater.
Cheap kotatsu (75 × 75cm) costs around 7000 yen like in these photos. (not including the blanket) Of course, better quality and larger ones cost more.

We place our legs under the Kotatsu while sitting on the floor.
Once you sit in Kotatsu, it is hard to exit from it, because it is really comfortable.

I sometimes spent nights lying under the table.
However, it is not a bed, and I realized I had slept all night long in Kotatsu.

The heater is a consumable part of kotatu. When you use it for several years, it might get broken. When that happens, you can buy a replacement at electrical shops or online.

I don't recommend to sleep in Kotatsu for long hours, because sleeping long periods in Kotatsu makes our bodies sluggish and tired.
Nevertheless, sleeping in Kotatsu is nice and warm. I can't stop using Kotatsu during winter.

If you use a Kotatsu you can save more money on electricity than using an air conditioner or an electric heater.

In Japan, many furniture store sell Kotasu mainly in winter.


Looking around furniture and household goods store might be fun for international tourists.

If you are traveling to Tokyo during the cold season and you would like to try the experience of using a Kotatsu,

Usually Kotatsu is available at a ryokan 旅館 that is a type of Japanese style inn. However, in Hokkaido 北海道 district that is the northeast part of Japan, people don't use Kotatsu because Kotatsu is not enough to live in such a cold climate in winter.

In downtown Tokyo, I know there is a restaurant that offers the choice of a Kotatsu table as a seating option starting from October 1st through around March.

It’s possible that there are other restaurants that offer Kotatsu tables as well, but I suggest you check beforehand to see if the restaurant has them.
Check out below.
