The haiku is a Japanese form of poetry which evolved out of the philosophy of Zen Buddhism. Traditional Japanese haiku have 17 syllables, but it has been suggested that English haiku should have more syllables, because English is a more long-winded language than Japanese, and you can pack a lot more concepts into 17 Japanese syllables than you can into 17 English syllables. However, I tend to stick to the 17 syllable structure, divided into 3 lines of 5, 7 and 5 syllables. Haiku also traditionally include a kireji, a ‘cutting word’. The cutting word divides the poem into two contrasting sections with imagery that adds a surprising twist or contrast to each other. It’s difficult to find ‘cutting words’ in English, so haiku writers in English use a dash to separate the two sections of the poem.
Haiku are essentially poems about Nature, so Japanese haiku also have a season word, to indicate in what season the action of the poem takes place. The season word does not have to be the name of the season; it can be something that is obviously associated with that season – for example, plum blossom would indicate that the poem was describing spring.
The imagery of a haiku is simple and unpretentious, and generally does not use similes to achieve its effects. The natural phenomena described may very well be metaphors for something else, but the haiku may also be enjoyed for the images of natural beauty, and the human response to it, that it conjures up.
Haiku poets would often gather together to compose haiku on the spot. One poet would begin, and then another poet would respond with a haiku of their own, and in this way a series of linked haiku (known as haikai-renga) would be composed by the group.
Sometimes haiku would be combined with travel writing or other prose. The most famous example of this form is The Narrow Road to the Deep North by Matsuo Basho, which describes Basho’s travels to the far north of Japan. The combined haiku and prose form is known as haibun.
Writing haiku teaches one to strip things back to the bare essentials, to distil experience into its pure form, and to observe Nature closely. It is a very satisfying process, because haiku are so short, and so complete in themselves.
