In general, insulation in Japanese homes is poor, so that means during winter heating devices have to be constantly on, driving up heating bills and sapping the power grid. Though this winter is predicted to be warmer than most, many Japanese, aware of energy shortages, will be feeling more than usually chilly as they try to cut down on power consumption.
A traditional method of beating this problem is the kotatsu, a low table that has a heating element underneath and a warm blanket hanging down from all sides; by turning up the heat on legs and feet, the main heating device in the room can be turned down, thus saving energy. Modern methods of keeping nice and toasty without resorting to turning up the room heater are understandably catching on. We’ve compiled a list of the best:
King Jim’s Urapoka: This nifty heating device transforms your desk into a kotatsu. After attaching the heat-sealing flaps to the sides of your desk, simply pop the device under your feet to warm up those frozen toes. 30W, ¥7,329.
Humanoid Sleeping Bag from Doppelganger Outdoor: Specially selected by Nikkei Trendy as one of the best energy-saving products for winter on the market, if you snuggle up in these caterpillar suits, you probably won’t need to bother switching on the heater at all. It’s possible to unzip hands and feet to free them up for work, though the puffy style probably falls outside the bounds of smart casual business attire. ¥11,550.
Heat Tech underwear, Uniqlo: A survey conducted in October by Nikkei BP’s AIDA showed that over 60 percent of Japanese were intending to wear some from of “underwear”(including short and long t-shirts and short and long shorts) to protect against the cold this winter. Most modern innerwear is designed to have quick drying properties and, of this type, over 50 percent of both men and women favored Uniqlo’s heat tech range. This year sales of heat tech products are up 25 percent from last year, according to Sankei Biz.
Nitom’s Transparent Window Glass Film: Since double-glazing is rare in Japan, many people simply opt to insulate by sticking plastic sheeting directly onto window glass. A newish kind of insulation that sticks onto the window frame, rather than directly onto the glass, thus creating an air pocket, is very popular this year. According to Sankei Business, sales of the stuff during November were triple that of the same period the previous year.
