A haiku is a brief poem, based originally on the type of Japanese poem by that name, but now written in over 25 languages and more than 50 countries. Related forms include haikai no renga (also known as renku) or linked poetry, haibun (prose with haiku), and tanka ("short poems" a little longer than haiku and more openly emotional). See the FAQ for definitions. Web sites that actively request submissions for online or print journals are being moved into the "haiku publications" subcategory.
