Haiku Anthology of Poems and Poets from Bashô to Shiki" by Harold G. Henderson was published by Doubleday Anchor Books. This book was a revision of Henderson's earlier book titled "The Bamboo Broom" (Houghton Mifflin, 1934). After World War II, Henderson and Blyth worked for the American Occupation in Japan and for the Imperial Household, respectively, and their shared appreciation of haiku helped form a bond between the two. Henderson translated every hokku and haiku into a rhymed tercet (a-b-a), whereas the Japanese originals never used rhyme. Unlike Yasuda, however, he recognized that 17 syllables in English are generally longer than
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),
