kadomatsu
A kadomatsu (literally "gate pine") is a traditional Japanese decoration of the New Year placed in pairs in front of homes to welcome ancestral spirits or kami of the harvest. They are placed after Christmas until January 7 (or January 15 during the Edo period) and are considered temporary housing (shintai) for kami. Designs for kadomatsu vary depending on region but are typically made of pine, bamboo, and sometimes ume tree sprigs which represent longevity, prosperity and steadfastness, respectively.
