Kotatsu is absolutely imperative item in Japanese winter.
The Kotatsu is a table which has a heater under side and it is covered with a warn blanket, so the inside the Kotatsu is always kept warm.
It is usually placed in a living room then people get together because the Kotatsu is so warm.
Kotatsu, mandarin oranges and a cat inside the Kotatsu is typical sighs on a cold winter’s day in Japan.
It is a bit sad that the number of the young family today who do not have Kotatsu because it looks kinda old even they love Kotatsu.
