Noren are Japanese fabric dividers traditionally used by shops and restaurants in front of the entrance usually with their logo printed. It's not hard to find shops that hang Noren all over Japan, but usually traditional type shops use them.
The noren you see in the top photo is from a traditonal Japanese confectionery called "Toraya", and this particular shop of Toraya uses Noren very differently. It's probably about 6-7 meters wide and is working as a room devider/screen/front door/shop sign/curtains. It works so well! I love it when I enter the shop through this noren, somehow it feels very nice :)
The first 3 photos are found in Tokyo and the bottom five from my recent trip to Kanazawa.
You can also see a wonderful post on Noren here at ii-ne-kore. So check that out too!
