This paper was purchased in October 2014 in Ogawa-machi, a town registered as an Intangible Cultural Heritage site. It is antique paper, over 10 years old. I don't know much about this paper, but the "kawa-gami" (bark paper) is thick and sturdy. The light brown paper is also somewhat thick and sturdy.
