Haiku in English four lines (sometimes known as "haiqua") or longer have been written, some of them "vertical haiku" with only a word or two per line. These poems mimic the vertical printed form of Japanese haiku. The translator Nobuyuki Yuasa considered four lines more appropriate in his translations, being closest to the natural conversational rhythm of the colloquial language of haiku, also that three lines did not carry the weight of hokku and found it impossible to use 'three lines' consistently for his translations. The contemporary poet John Martone has written a vast number of vertical haiku. Haiku have also appeared in
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.
