I have studied about Japanese paper, well… in Japan. I bought a few sheets of different sorts and brought with me to America. I experiment with it and I really enjoy the outcome. However it is not easy to work with it, any paint spot of watercolor or any other pair remains on the paper permanently, which leaves so little space for an error.
Different sorts of paper are designed for different purposes and have a very big price range, depending on how much of handworks was involved.
On Jerry’s Artarama site I found the following qualification of kinds of Japanese papers, which you may find useful:
