Haiga(俳画haiga, haikai drawing) is a style of Japanese painting based on the aesthetics of haikai, from which haiku poetry derives, which often accompanied such poems in a single piece. Like the poetic forms it accompanied, haiga was based on simple, yet often profound, observations of the everyday world. Stephen Addiss points out that "since they are both created with the same brush and ink, adding an image to a haiku poem was... a natural activity."
