Power saving puts Christmas illuminations in a new light

The Winter Sakura lights along Meguro River are powered by used cooking oil

As is the tradition, Christmas lights are twinkling all over Tokyo. When it comes to Christmas decorations the Japanese, who tend to go wild for the glitziest, brightest possible displays, aren’t exactly famed for their self-restraint, so this year poses the problem of how to accomplish the desired amount of dazzle without being seen as an energy hog.

The most obvious answer, and the most popular one, is to swap out normal bulbs for energy-efficient LED lights. Due to LED bulbs’ power-saving qualities, ad agency Dentsu has rated them as the second most popular product in Japan for 2011.

According to Sankei News, Keikyu Railways and the New Otani Hotel have both switched to LED lights. But Ebisu Garden Palace has not only switched over the bulbs of its gigantic Baccarat Crystal chandelier, it’s also reduced the number of bulbs from 60,000 to 40,000. On top of that a solar power panel has been installed to supplement the power supply. The Grand Prince Hotel Takanawa’s, however, have outstripped this effort by installing an entirely solar-powered display of LED lights in its Japanese garden.

Though the hotel’s garden sounds attractive, our favorite eco-friendly display in Tokyo is the “Winter Sakura” illuminations along the Meguro River. Pink LED bulbs are strung on the branches of trees along the river so that it appears as if the cherry blossom trees are blooming out of season. Better yet, the lights are powered from bio diesel made from used cooking oil collected from homes and restaurants in the area.

Some businesses have decided that the best way to do their bit, however, is to dodge the whole issue by not putting up any decorations. SG Holdings, for instance, who run Sagawa Express Ltd. announced that in light of power-saving measures, they decided to cancel any plans for illuminations that might have been put up at their head office or branch offices. This seems a pity especially seeing as Nikken Release Kyogo Ltd has begun renting out eco-friendly LED Christmas trees to meet the demand for a setsuden (power saving) Christmas.
