Moriya Jihei, born Ishikawa Jihei, was a publisher of ukiyo-e prints based in the Nihonbashi neighborhood of Edo (later Tokyo). He worked with a number of artists, including Hokusai, Utamaro, and Kunisada. Due to the incredible length of his dates of activity, it is quite unlikely that Moriya Jihei was a single individual; rather, it is likely that his successor took on his name, or at least continued to use that name in his professional capacity as a publisher. - http://www.wiki.samurai-archives.com/index.php?title=Moriya_Jihei
