Haikai

Haikai (Japanese 俳諧 comic, unorthodox) may refer in both Japanese and English to haikai no renga (renku), a popular genre of Japanese linked verse, which developed in the sixteenth century out of the earlier aristocratic renga. At the time, it "meant vulgar, earthy renga, full of satire and puns", though "under the influence of Bashō (1644-1694) the tone of haikai no renga became more serious." "Haikai" may also refer to other poetic forms that embrace the haikai aesthetic, including haiku and senryu (varieties of one-verse haikai), haiga (haikai art, often accompanied by haiku), and haibun (haiku mixed with prose, such as in the diaries and travel journals of haiku poets). However, haikai does not include orthodox renga or waka.
