Kokkeibon  The was a genre and type of early modern Japanese novel. It came into being late in the Edo period during the 19th century. As a genre, it depicted the comical behavior occurring in commoners' daily lives. The "kokkeibon" genre is the successor of the "dangibon" genre. Jippensha Ikku's "Tōkaidōchū Hizakurige" (1802–1822) is identified as the first representative novel. A less strict definition includes the "dangibon" as an "early "kokkeibon"". "Kokkeibon" generally consists of dialogue among the main characters and includes illustrations. The genre was most popular between 1804 and 1830, and is most representative by the works of Jippensha Ikku and Shikitei Sanba.
