Sugidama

@Nicole: Thanks for your comment.
This is an object made of the leaves of the cedar tree.
This object is called sugidama ("cedar ball") or sakabayashi ("sake forest") and is used as a kind of store sign for sake breweries.
When new sake is ready, a fresh, green sugidama is hung.
This not only symbolizes that the sake is well made, but it also calls for the blessing of the gods.
At the end of the year—when that new sake is usually ready—a new, fresh green sugidama is usually hung, giving a kind of thanks for the previous year's production.
Then, as the sake-making process is begun again, the sugidama gradually withers and turns brown, mirroring the fermenting process that is occurring in the workshop.
So the sugidama, which is a symbol for the sale of sake, becomes a symbol for the sake itself.

You'll have the chance to see.
