“Paper Nao” is a shop that specializes in Japanese and Asian handmade paper. In their two-story building, there are 30 to 40 thousand pieces of Japanese paper (“washi”), foreign paper, and antique paper. Mr. Naoaki Sakamoto who is the owner of this shop and also a papermaking craftsman himself, has travelled all over the world to visit the product makers in person for his selection of papers. He claims that visiting the production sites and seeing the environment with his own eyes is an important process in selecting papers.
