Let's talk about these Japanese tables.


What is a Kotatsu Table?

A kotatsu table is a living room furniture that originated from Japan. Usually found in the middle of a room, it's a short table with a custom futon that can seat several people at once. It's a literal space warmer that families and friends use to keep themselves toasty and cozy during the colder seasons.

While modern-day kotatsu tables use electricity to generate heat, Japanese people originally had a completely different heating system in their houses. During the 14th century, Japanese people had irori in their homes, an underground hearth that used charcoal as the main heat source.

Initially, they placed seating pads near this heat source to protect themselves from getting burned. The Japanese soon switched to electricity to power their heated tables instead of using a charcoal burner or a charcoal heater. In the evolution of the kotatsu table, Japanese people began using quilts to trap the heat and ensure that the temperature in their space stayed toasty warm. Over the years, kotatsu tables became a staple of the average Japanese home.

How much does it cost

A full Kotatsu table set can cost $378 and up.

If you want to build your own, you can also buy separate parts of the set on their own. For example, you can purchase the base table for around $180 at the lowest. Depending on the quality, you can also get the transformer (heating unit) and futon (blanket) at around the same price range.

Kotatsu tables are primarily used to keep oneself warm during the cold seasons. In a Japanese home, this table is usually held in the middle of the room as a literal central heating tabletop.

This low table has a heating element that allows several individuals to stay warm in winter, fall, or cold weather. A kotatsu heated table can service around 6 people or more, depending on the size of the table and the room in a Japanese household.

However, during the summertime, people often remove the blanket part of the Japanese kotatsu table and the transformer or the electric heater. They keep the cozy yet heavy blanket in a storage space together with a kotatsu heater.

And so, they have successfully converted the warm blanket table into a somewhat sizeable coffee table.

Is it Worth it?

If you're someone who likes to keep warm and cozy the entire year, then you should have a Japanese kotatsu table in your home.
