門松 is a traditional Japanese decoration made from pine branches, bamboo, and sometimes plum blossoms. It is placed at the entrance of homes during the New Year season to welcome ancestral spirits and bring good fortune for the coming year. The use of pine symbolizes longevity, while bamboo represents strength and resilience. Typically, 門松 is arranged in a specific way, with the bamboo cut at different heights to create a visually appealing design. These decorations are usually displayed from late December until January 7, marking the end of the New Year celebrations in Japan.
