Renku Renku , or , is a Japanese form of popular collaborative linked verse poetry. It is a development of the older Japanese poetic tradition of "ushin" renga, or orthodox collaborative linked verse. At renku gatherings participating poets take turns providing alternating verses of 17 and 14 morae. Initially "haikai no renga" distinguished itself through vulgarity and coarseness of wit, before growing into a legitimate artistic tradition, and eventually giving birth to the haiku form of Japanese poetry. The term "renku" gained currency after 1904, when Kyoshi Takahama started to use it. The oldest known collection of haikai linked verse appears
Haiku theoretician F. S. Flint, who passed on Couchoud's ideas to other members of the proto-Imagist Poets' Club such as Ezra Pound. Amy Lowell made a trip to London to meet Pound and find out about haiku. She returned to the United States where she worked to interest others in this "new" form. Haiku subsequently had a considerable influence on Imagists in the 1910s, notably Pound's "In a Station of the Metro" of 1913, but, notwithstanding several efforts by Yone Noguchi to explain "the hokku spirit", there was as yet little understanding of the form and its history.
