Haiga (俳画) is a style of Japanese painting which erived from the same aesthetics and ideas as haikai and haiku poetry, and 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."
