The dangibon (談義本) was a pre-modern Japanese literary genre.
Texts were written in a humorous, satirical sermon-style with the purpose of educating the masses.
Masuho Zankō (増穂残口) and Issai Chozan (佚斎樗山) are credited with establishing the early foundations upon which the genre rests.
In 1752, Jōkanbō Kōa (静観房好阿) wrote Imayō Heta Dangi (当世下手談義, "A Clumsy Sermon in the Modern Manner"), which is identified as the first true example of the dangibon genre.
"[1] It gradually evolved into the kokkeibon genre at the start of the 19th century.
