Haiku.

A haiku is a three-line poem with a strict syllable pattern: five syllables in the first line, seven in the second, and five in the third. That’s the basic structure. Within those seventeen syllables, a traditional haiku also includes two important elements: a *kigo* (a seasonal word or image that ties the poem to a specific time of year) and a *kireji* (a "cutting word" or pause that separates the poem into two contrasting images or ideas, allowing the space between them to create meaning).

Tradition

This form originated in Japan, evolving from the opening stanza of a longer collaborative poem known as renga. Matsuo Bashō in the seventeenth century is credited with transforming that opening stanza into a standalone art form. His students, Yosa Buson and Kobayashi Issa, continued this tradition, and in the early twentieth century, Masaoka Shiki further modernized it, even coining the term haiku.

The form made its way into English in the early 1900s and quickly gained popularity. Imagist poets like Ezra Pound embraced its brevity and the technique of placing two images side by side without clarifying their relationship. What keeps the haiku vibrant is this very restraint: it doesn’t dictate your emotions. It presents a frog, a pond, a splash, and then it leaves you to ponder the connection.

Why it works

Pound described this poem as an attempt to create a haiku in English. It stretches the syllable rule while maintaining the core aspect of the form: placing two images next to each other without linking them. Human faces turn into flower petals, and the crowd transforms into a branch. The semicolon serves as the cut. Pound's remark about condensing a thirty-line draft into these two lines highlights a key lesson in haiku thinking — the form encourages you to discard everything except the juxtaposition.

How to spot haiku

Look for these key features:

  1. Three lines. Exactly three lines are required. If the poem has more, it doesn't fit the traditional haiku form (though you may find sequences of haiku).
  2. Syllable count of 5-7-5. Count the syllables in each line. A perfect total of 17 syllables across the three lines is the clearest indicator, although English-language haiku may sometimes relax this rule.
  3. A seasonal or nature image (kigo). Traditional haiku typically include a word or phrase that indicates a season, such as cherry blossoms, snow, cicadas, or harvest moon.
  4. A cut or juxtaposition. The poem usually shifts at some point, typically between the first and second lines or the second and third lines. Two distinct images or moments are placed side by side without explanation.
  5. No rhyme scheme. Haiku do not rhyme. If you notice end rhyme, it's probably a Western imitation that has strayed from the original form.
  6. Present-tense immediacy. Most haiku are written to convey a moment happening right now, rather than reflecting on the past or offering analysis.
  7. No title (traditionally). Classical haiku often lack titles; the first line serves as the identification.

How to write haiku

Follow these steps:

  1. Find a moment, not a thought. Haiku resist abstraction. Start with something you actually observed: a specific sound, a specific light, or a specific creature doing a specific thing. "Loneliness" won't work as a haiku subject. Instead, go for "A single crow on a telephone wire at dusk."
  1. Identify your two images. The form lives in the gap between two things. Ask yourself: what second image does the first image bring to mind? You're not hunting for a metaphor to explain; instead, seek a pairing that sparks a small electric charge when placed side by side.
  1. Decide where the cut goes. The cut (your kireji equivalent in English) usually lands at the end of line one or line two. A dash, a colon, or simply a line break can accomplish this. The cut separates your two images and allows the white space between them to carry meaning.
  1. Draft in 5-7-5. Write the three lines to fit the syllable count. Don’t stress yet about achieving a perfect count—focus on capturing the images first, then tweak word choices to fit. This is where the form’s strictest constraint comes into play: you might need to swap a two-syllable word for a three-syllable synonym or remove an article you’d usually include.
  1. Include a seasonal anchor. Add a word that places the poem in a season. It doesn't have to be as direct as "spring"—terms like "mud," "bare branch," or "first firefly" work just fine.
  1. Cut every word that explains. Read your draft and eliminate any word that tells the reader how to feel or what the images mean. If you’ve included "sadly" or "which reminds me of," cut it out. Trust the power of the juxtaposition.

Inquiries

Does an English haiku have to follow the 5-7-5 syllable count exactly?

Strictly speaking, yes — that's how the form is defined. However, many respected English-language haiku poets believe that Japanese on (sound units) don't align neatly with English syllables, and a strict 5-7-5 count in English can lead to poems that feel forced. The Haiku Society of America’s working definition offers some flexibility. For beginners, it's best to stick to 5-7-5; once you grasp the reasoning behind the count, you can choose when to adjust it.

What is a kigo, and do I need one?

A kigo is a word that refers to a specific season — it comes from the Japanese saijiki, which is like an almanac listing words linked to each season. Traditional haiku typically include one. In English haiku, this isn't as strict, but using a seasonal or natural image usually enhances the poem. It ties the moment to the physical world and links the poem to a broader cycle, contributing to the depth of haiku, even though it's so brief.

What's the difference between a haiku and a senryū?

A senryū maintains the 5-7-5 structure but doesn't require a kigo; instead, it highlights human nature, often incorporating irony or humor rather than observations of nature. If your three-line poem centers on someone's ridiculous behavior instead of a seasonal scene, it's likely a senryū. The distinction between the two forms can be subtle, and many poets create both types without being overly concerned about the classification.

Who are the essential haiku poets to read?

Start with the three classical Japanese masters: Matsuo Bashō from the 17th century, Yosa Buson from the 18th century, and Kobayashi Issa, who spanned the 18th and 19th centuries. For a look at how the form has modernized, check out Masaoka Shiki. In English literature, Ezra Pound’s Imagist poems reveal the direct influence of haiku. For a taste of contemporary English haiku, Frogpond and Modern Haiku are the go-to journals to explore the current state of the form.

What is a haiku sequence or haibun?

A haiku sequence consists of interconnected haiku that together create a broader narrative or reflection that one poem alone can't express. Haibun is a similar style that mixes prose sections with haiku—Bashō's travel diary Oku no Hosomichi (Narrow Road to the Deep North) is a well-known example. Both formats allow poets to utilize the brevity of haiku while exploring deeper emotional or storytelling themes.

What are the most common mistakes beginners make?

Three mistakes appear repeatedly. First, crafting a description that lacks contrast—three lines repeating the same idea with different wording, failing to create any tension. Second, concluding with a statement of feeling ('I feel so alone') instead of an image that evokes that emotion. Third, imposing a syllable count by inserting filler words ('the,' 'so very,' 'it is') that contribute nothing. The form is compact enough that every word carries weight.

Can a haiku have a title?

Classically, no. Traditional Japanese haiku don’t have titles, and this absence adds to the form's directness — it immerses you immediately in the moment. In English-language practice, some poets do include titles, particularly in sequences where a title helps guide the reader. If you're crafting a standalone haiku, give it a shot without a title first. You might discover that the poem feels more powerful without one.
