I'm enjoying the kadomatsu while I can - they'll be gone in the next few days. It's traditional to burn them as New Years celebrations draw to a close to appease the spirits which make the kadomatsu their temporary homes. These arrangements flank doorways and entrances where they welcome ancestral spirits and offer promise of bounty and fertility for the harvest. Traditionally, they're laden with symbolism, and composed of elements which represent hopes for the new year.
I think they're lovely.
