This spectacular curtain is called Noren. Noren is a Japanese word which means a traditional fabric which is hung on a window or in a doorway. I guess it can also be used as a shower curtain or as tapestry. You are in luck because it can been shipped to the US and will cost you $25.90.
Naomi (the shop owner) doesn't stop with this. She hand makes everything from fabric brooches, purses to Kokeshi (Japanese wooden dolls). And, you won't believe me but she handcrafts "good luck" origami earrings.
