A haiku is a non-rhyming 3-line 17-syllable poem, traditionally about the seasons or nature. The first line has five syllables, the second line has seven syllables, and the third line has five syllables. (The word “haiku” should not have an uppercase H, except at the beginning of a sentence or in a title, and the singular and plural forms of the word are the same.


Japanese Haiku
Traditional Japanese haiku are short non-rhyming poems which generally have the same three characteristics:

  1. Seventeen phrases—known as on or morae
  2. A cut between two ideas, represented by a punctuation mark or a cutting word
  3. A word associated with one of the seasons

Japanese haiku are not based upon 17 syllables, as many people believe. They are based upon 17 sound meters, known as on or morae. The on (sound meters), when counted the way syllables would be counted in English, can number anywhere from 14 to 18 or more.

Kiru (Cut) and Kireji (Cutting Word)
Kiru is the Japanese word for cut. It represents the idea that when composing a haiku, one’s thoughts are cut into two sections. In the modern haiga (haiku with photographic image) at the top of this article, my thoughts are cut between the second and third lines of my poem.

Kireji is the punctuation mark or word that figuratively cuts the haiku into two parts.  In my modern haiga above, I used the ellipsis () to cut my haiku into two parts. The ellipsis is my kireji.

Kigo (Seasonal Reference)
A kigo is a word used in Japanese poetry to represent one of the four seasons. The word does not have to be the name of a season. It can be any word related to a season or nature. Translated into English, the kigo may appear as a phrase.

English Language Haiku
Haiku written in English developed from the traditional Japanese form of haiku, but there are differences between the two forms of poetry. Poetry written in English is concerned with meter, so syllables are counted when writing a haiku. Seventeen syllables is the norm when writing haiku in English, but fewer syllables is acceptable, and is not considered to be incorrect.

There aren’t strict rules for writing English language haiku, but there are some common characteristics for this type of poetry:

  1. No more than seventeen syllables — written on three lines or less
  2. A cut or cutting word between two ideas
  3. A word associated with a season or nature should be used, but it doesn’t necessarily have to be a traditional Japanese kigo. Baseball, for example, can be used as a kigo in a summer haiku. Football can can be used as a kigo in an autumnal haiku.
