What a haiku is

A term you'll meet in Japanese poetic form.

A haiku is a very short Japanese poem that captures a single, vivid moment of perception — usually a flash of the natural world held still. Most readers learn it as three lines of five, seven, and five syllables, but the real form is subtler than the syllable count suggests.

Beyond 5-7-5

The famous "5-7-5" describes Japanese sound-units (on), which don't map neatly onto English syllables; many fine English haiku are shorter. What matters more than the count are two traditional elements: a kigo, a season word that anchors the poem in a time of year, and a kireji, a "cutting word" that creates a pause or break.

The cut

That cut is the heart of haiku. It splits the poem into two images and lets them strike against each other, leaving the connection unspoken. Bashō's most famous haiku sets an old silent pond against a frog's sudden splash — and trusts the gap between them to do the work. The reader supplies the meaning.

What it's really doing

A haiku doesn't explain or moralise; it points. It is the art of juxtaposition stripped to essentials: two concrete images, no commentary, a single breath of attention. The emotion arises from the things themselves, never from the poet telling you how to feel.

How to read one

Read slowly and resist the urge to "decode" it. Find the two halves and the cut between them; let the images sit side by side. A good haiku rewards stillness — it gives you a moment, not a message, and asks only that you actually look.
