Haiku matter. The loosening of traditional standards has resulted in the term "haiku" being applied to brief English-language poems such as "mathemaku" and other kinds of pseudohaiku. Some sources claim that this is justified by the blurring of definitional boundaries in Japan. Subsequent to Paul-Louis Couchoud’s popularisation of the form in France through his essays and translations, the next major haiku collection to appear there was the sequence of war poems by , "Cent visions de guerre" (1916). Later haiku by him were included among the work of the twelve published together in the "Nouvelle Revue Française" (No. 84, September 1920),
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.
