Renga (連歌, collaborative poetry) is a genre of Japanese collaborative poetry. A renga consists of at least two ku (句) or stanzas. The opening stanza of the renga, called the hokku (発句), became the basis for the modern haiku form of poetry.
Renga was one of the most important literary arts in pre-modern Japan. The earliest surviving renga is in the Man'yōshū, where Ōtomo no Yakamochi and a Buddhist nun (尼 ama ) made and exchanged poems with sound unit counts ("on") of 5-7-5 and 7-7. This two-verse style is called tan-renga (短連歌, "short renga"). Other styles are called chō-renga (長連歌, "long renga"). A comparable, though less evolved, tradition of 'linked verse' (lián jù 連句 - the same characters as 'renku') - evolved in Chin-dynasty China, and this Chinese form may have influenced Japanese renga during its formative period. However there are major differences between the two, the Chinese having a unity of subject and a general lightheartedness of tone, neither of which characteristic is present in Japanese renga; furthermore, the history of Japanese poetry shows renga as an apparently natural evolution.
Around the time the Shin Kokin Wakashū was compiled, the renga form of poetry was finally established as a distinct style. This original renga style, hyakuin renga (百韻連歌, "100-stanza renga") consisted of one-hundred links, used only the standard poetic diction (歌言葉 utakotoba ) that had been established in the Kokinshū, used sound unit counts of 5-7-5 and 7-7, and finished with two lines of 7 sound units each. At this time, poets considered the use of utakotoba as the essence of creating a perfect waka, and use of any other words was considered to be unbecoming of true poetry.
Many rules or shikimoku (式目) were formalized in the Kamakura and Muromachi periods specifying a minimum number of intervening stanzas before a topic or class of topics could recur. Renga was a popular form of poetry even in the confusion of Azuchi-Momoyama period. Yet by the end of this era, the shikimoku had become so complicated and systematic that they stifled the active imagination that had been a part of the renga's appeal. During the medieval and Edo periods, renga was a part of the cultural knowledge required for high society.
In the Edo period, as more and more ordinary citizens became familiar with renga, shikimoku were greatly simplified. The 36-verse Kasen became the most popular form of renga, and commonly spoken words as well as slang and Chinese words were allowed. With this relaxation of the rules, renga were able to express broader humor and wit. This style of renga came to be called haikai no renga ("comical linked verse") or simply haikai, and Matsuo Bashō is known as the greatest haikai poet.
The most favored form of renga in the Edo period was the kasen (歌仙), a chain consisting of 36 verses. As a rule, kasen must refer to flowers (usually cherry blossoms) twice, and three times to the moon. These references are termed hana no za (花の座, "the seat of flowers") and tsuki no za (月の座, "the seat of the moon").
The first stanza of the renga chain, the hokku, is the forebear of the modern haiku. The stand-alone hokku was renamed haiku in the Meiji period by the great Japanese poet and critic Masaoka Shiki. Shiki proposed haiku as an abbreviation of the phrase "haikai no ku" meaning a verse of haikai.
For almost 700 years, renga was a popular form of poetry, but its popularity was greatly diminished in the Meiji period. Masaoka Shiki, although himself a participant in several renga, claimed that "(Renga is) not literature" (「文学に非ず」 Bungaku ni arazu )"連歌・連句 (Renga, Renku)". Japan Dictionary (日本辞典 Nihon-Jiten ). Retrieved 23 December 2012.. The renga's appeal of working as a group to make a complete work was not compatible with the European style of poetry gaining popularity in Japan, where a single poet writes the entire poem.

Renga terminology 
- hokku (発句): The first stanza of renga with a 5-7-5 sound unit count. This stanza should be created by a special guest when present, and is considered a part of the greeting in a renga gathering. It must include a kigo (季語, "seasonal word"), as well as a kireji (切字, "cutting word" - a break in the text, usually, but not always, at the end of a line). The kigo usually references the season the renga was created in. Hokku, removed from the context of renga, eventually became the haiku poetry form.
- waki (脇): The second stanza of a renga with a 7-7 sound unit count. The one who helped to organize the gathering is honored with creating it.
- daisan (第三): The third stanza of a renga with a 5-7-5 mora count. It must end with the -te form of a verb to allow the next poet greater freedom in creating the stanza.
- hiraku (平句): Refers to all verses other than the hokku, waki, daisan, and ageku.
- ageku (挙句): The last stanza of a renga. Care should be taken to wrap up the renga.
- kuage (句上げ): A note made after the ageku to indicate how many ku each poet read.
- kōgyō (興行): To hold a renga gathering. May also be called chōgyō (張行).
- wakiokori (脇起り): To start with the hokku of a famous poet such as Bashō and make a new waki verse to follow on from there.
- tsukeai (付合): May also be called tsukekata (付け方) or tsukeaji (付け味). Refers to the mixing and matching of unlikely word combinations to spur imagination or evoke an image. One of the interesting features of renga.
- maeku (前句): The verse in which tsukeai happens.
- uchikoshi (打越): The verse before the maeku.
- shikimoku (式目): A set of rules to lay out the stylistic requirements for change throughout the poem and to prevent a renga from falling apart.
- renku (連句): Modern renga in Bashō's style.
- kukazu (句数): Literally, "the number of verses". When the theme of a section is a popular topic such as "Love", "Spring", or "Fall", the renga must continue on that theme for at least two verses but not more than five verses. This theme may then be dropped with one verse on any other topic.
- sarikirai (去嫌): A rule to prevent loops repeating the same image or a similar verse.
- rinne (輪廻): The name for a loop where the same theme, image, or word is repeated. Term taken from Buddhism.
- kannonbiraki (観音開き): A type of loop where the uchikoshi and tsukeku have an identical image or theme.
- haramiku (孕み句): A stanza prepared beforehand. Should be avoided as stanzas should be created on the spot.
- asaru (求食る): To make two stanzas in a row. Happens frequently when the dashigachi rule is used. Should be avoided to let others join.
- dashigachi (出勝ち): A rule to use the stanza of the first poet to create one.
- hizaokuri (膝送り): A rule whereby each poet takes a turn to make a stanza.
- renju (連衆): The members of a renga or haikai gathering. The members of a renga gathering are also called kaishū (会衆).
- ichiza (一座): Literally, "one seating". Describes the group when the renju are seated and the renga has begun.
- sōshō (宗匠): May also be called sabaki (捌き). The coordinator of an ichiza, he or she is responsible for the completion of a renga. Has the authority to dismiss an improper verse. The most experienced of the renju should be the sōshō to keep the renga interesting.
- kyaku (客): The main guest of the ichiza and responsible for creating the hokku.
- teishu (亭主): The patron of a renga gathering, who provides the place.
- shuhitsu (執筆): The "secretary" of the renga, as it were, who is responsible for writing down renga verses and for the proceedings of the renga.
- bunnin (文音): Using letters (i.e. the post), telegraph, telephone, or even fax machines for making a renga. Using the internet is also considered a form of bunnin.
