He-gassen
He-Gassen, or Houhi-Gassen, are titles given to a Japanese art scroll, created during the Edo period by an unknown artist or several unknown artists.
The scroll depicts various scenes with one peculiar characteristic reoccurring throughout the scroll: at least one character is having a bout of flatulence directed against the other characters. The scroll may have been made to highlight the political and social changes in Japan.
The scroll has been digitized by the Waseda University Library.
