“Shimekazari(注連飾り)” is a New Year's decoration  - a twisted straw rope with fern(シダ) leaves, an orange and other items of good omen. It is generally hung on doors during the New Year holidays and served as a charm against evil spirits.
A twisted straw rope is called “Shimenawa(注連縄)” which is used in the Shinto religion. It is often found in front of shrines or other sacred locations.
Originally New Year’s day is the day when New Year’s god visit houses and give us the power of living and happiness. So we prepare to welcome God decorating Shimekazari on the entrance door. 2015-01-01 08.11.15
