Celebrating Christmas in Japan is an “import” from Western countries. Apart from the tradition of giving presents to others, one of the things that the Japanese have imported is Christmas lights. In most places the Christmas illumination consists of thousands of blue LED light bulbs and the themes are usually more romance-based than Christmas-based. This is the ranking of the places in Japan with the best Christmas illumination in 2013.
