A couple of days ago I ordered some fabric from the Kokka retail shop. It has already arrived! Amazing service! The staff emailed me to query a couple of things, let me know when the order had shipped and there were no mistakes. I'm looking forward to using them again. The site is all in Japanese but it's still lovely to see all the pictures of the fabrics. They only ship domestically and orders must be completed in Japanese. Payment by cash on delivery, credit card or bank transfer.
