That is, standard american haiku. Whoever made the 5-7-5 rule so solid for english needs their head examined.
The true definition of a haiku is a three-lined poem with the first and third lines having the same amount of kana with the second line having two additional kana. the first and third lines may not exceed 8 kana each.
Translation: A haiku can be as large as 8-10-8, or as small as 1-3-1. If one makes a series of haiku, each individual one must follow the same size.
