given his incredible output, it is not surprising that kunisada was active in various genres, including "kabuki-e" and "yakusha-e" ("kabuki" actor pictures), "bijin-ga" (pictures of beauties), "yūrei-zu" (ghost pictures), "sumō-e" (sumo wrestler pictures), "shunga" (erotica), "musha-e" (warrior prints), and "uchiwa-e". he is also credited with popularizing "genji-e", a print genre related to the 11th century novel "the tale of genji", through his 1829-1842 book series, "nise murasaki inaka genji" ("a country genji by a fake murasaki"). in 1808, he began creating "yakusha-e", and these were to become the mainstay of his production, making up 60 to 70% of his total works. so prolific was he, that he came to be known as "kunisada, the portraitist of actors ("yakusha-e no kunisada")."
