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
Mora (linguistics) moraic system of writing. For example, in the two-syllable word "mōra", the "ō" is a long vowel and counts as two morae. The word is written in three symbols, モーラ, corresponding here to , each containing one mora. Such scholars also argue that the 5/7/5 pattern of the haiku in modern Japanese is of morae rather than syllables. The Japanese syllable-final "n" is also said to be moraic, as is the first part of a geminate consonant. For example, the Japanese name for "Japan", 日本, has two different pronunciations, one with three morae ("Nihon") and one with four ("Nippon"). In
