The humble domestic kotatsu is enjoying something of a revival since the disaster at Fukushima made the nation painfully aware of the need to conserve energy. The device is a table with a heating element underneath and a warm blanket draped over it keep one’s legs nice and toasty; without using up excess energy, the kotatsu has been keeping families huddled together in the winter months since its charcoal forerunner first warmed feet in the 14th century.
But what about those living alone, who want to bring down their electric bill but might not have room for a large kotatsu table?
Enter the mini kotatsu heater from Yamazen. On sale from September last year, Tokyo Walker reports that 18,000 of these tiny heated tables have already been sold. A wooden cage around the heating element protects the skin from nasty burns and a large blanket means that you can stretch out on the floor while enjoying the heat it kicks out. The device is also portable and can be placed under a desk to keep feet toasty while browsing the web. If you’re interested in buying one, Rakuten has them in stock for 5,580 yen.
