Haiku stimulated the writing of haiku in English. The Japanese-American scholar and translator Kenneth Yasuda published "The Japanese Haiku: Its Essential Nature, History, and Possibilities in English, with Selected Examples" in 1957. The book includes both translations from Japanese and original poems of his own in English, which had previously appeared in his book titled "A Pepper-Pod: Classic Japanese Poems together with Original Haiku". In these books Yasuda presented a critical theory about haiku, to which he added comments on haiku poetry by early 20th-century poets and critics. His translations apply a 5–7–5 syllable count in English, with the first and
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.
