Yes, a table. But a kotatsu isn’t just any old table. Designed to make it possible to survive winter without frostbite in Japan’s criminally underinsulated houses…

The kotatsu is such a necessity in every Japanese home that bringing it out when the weather turns frosty isn’t just shorthand for “it’s time to move the ice scraper from the glove box to the passenger seat,” it’s the universally accepted sleeping-cat-on-your-lap excuse for asking someone already braving the arctic wasteland of your apartment to fetch a tea refill.

Horribly underheated domiciles being something of a Japanese tradition, kotatsus have been the go-to winter survival solution since the 14th century, and not just for home use. Kotatsu boats had a definite edge over their appendage-numbing competitors…

And as long as we’re being honest, THIS is the kotatsu of everyone’s dreams. The one you never have to leave.
