Haiku (俳句, ) is a type of short form poetry originally from Japan. Traditional Japanese haiku consist of three phrases that contain a kireji, or "cutting word", 17 on (a type of Japanese phoneme) in a 5, 7, 5 pattern, and a kigo, or seasonal reference. Similar poems that do not adhere to these rules are generally classified as senryū. In Japanese, haiku are traditionally printed as a single line, while haiku in English often appear as three lines.
