Five lines. Thirty-one syllables. That is all a tanka asks for. But inside those five lines, you can fit a landscape, an emotion, and the precise moment where one becomes the other. I have been writing tanka on and off for years, usually in the margins of notebooks, usually when I notice something I cannot turn into a full poem but refuse to let go of. The tanka is the form for those moments.
What Is a Tanka?
A tanka is a five-line Japanese poem with a syllable pattern of 5-7-5-7-7. If the haiku is a photograph, the tanka is a photograph with a caption written by your heart. The first three lines, called the kami-no-ku or upper phrase, typically present an image or scene from the natural world. The last two lines, the shimo-no-ku or lower phrase, respond with a personal emotion, reflection, or turn.
The tanka is older than the haiku. Much older. It has been the dominant poetic form in Japan for over thirteen hundred years, dating back to the Nara period in the eighth century. The Man’yōshū, the oldest surviving collection of Japanese poetry compiled around 759 AD, contains more than 4,500 tanka. Emperors wrote them. Soldiers wrote them. Lovers sent them to each other the morning after.
The haiku actually evolved from the tanka. The first three lines of a tanka, the 5-7-5 upper phrase, eventually broke off and became its own form. So when people say the haiku is the essential Japanese poem, they are half right. The tanka came first. The haiku is its child.
Why the Tanka Works
The haiku gives you an image. The tanka gives you an image and tells you what it felt like to stand inside it.
That extra two lines, the 7-7 lower phrase, changes everything. A haiku about autumn leaves is a haiku about autumn leaves. A tanka about autumn leaves is about autumn leaves and also about how you felt watching them fall while thinking about someone who is no longer there. The tanka holds both the world and the self in the same breath.
This is why tanka has always been the form for love poetry in Japan. The Hyakunin Isshu, the famous anthology of one hundred poems by one hundred poets compiled in the thirteenth century, is almost entirely tanka. Most of them are about love, longing, or the particular ache of watching the seasons turn and knowing that time is doing the same thing to you.
The form works because of the pivot. The shift between the upper phrase and the lower phrase is where the tanka lives. The first three lines show you something. The last two lines tell you what that something meant to the person who saw it. The gap between looking and feeling is the poem.
The Structure
The traditional tanka syllable count is 5-7-5-7-7. In Japanese, these are measured in on, sound units that are shorter than English syllables. A strict 5-7-5-7-7 in English tends to run longer than the Japanese original, so many English-language tanka poets write shorter lines, aiming for the spirit of brevity rather than an exact count.
What matters more than counting syllables is understanding the two-part structure:
Lines 1-3 (upper phrase): An image, a scene, a moment from the world. Usually rooted in nature or a specific place. Concrete. Sensory. Present tense works well here.
Lines 4-5 (lower phrase): A personal response. An emotion. A memory triggered by the image. A reflection that deepens or complicates what the first three lines established.
The pivot between these two sections is everything. It should feel like a breath, not a break. The upper phrase leads naturally into the lower phrase, but the lower phrase takes you somewhere the image alone could not reach.
Original Tanka
Here are three to show you how the form works.
low tide at Roundstone,
the boats lean into the mud
like tired horses.
I have leaned like that myself,
waiting for the water’s return.
The upper phrase gives you a harbour image: boats at low tide, tilting in the mud. The lower phrase turns it personal. The poet sees herself in the boats, waiting for something to come back. The comparison is not stated as a metaphor. It is felt.
rain on the skylight,
each drop a small percussion
against the morning.
you left your book on the chair,
open to a page I have not read.
Here the upper phrase is purely sensory: rain, sound, morning. The lower phrase introduces another person through a single detail, an open book. The poem is about absence, but it never says the word. The unread page does that work.
blackberries ripen
along the lane to the sea,
the thorns hold them close.
some sweetness asks to be earned
with a little blood on your hands.
The upper phrase is observation. The lower phrase is philosophy, but rooted in the physical act of picking blackberries. The tanka does not separate thought from experience. It insists they are the same thing.
Tanka vs. Haiku
If you have read our post on the haibun, you already know that the haiku is about juxtaposition, two images placed side by side with space between them. The tanka is about connection. It does not leave a gap for the reader to cross. It builds a bridge.
The haiku trusts the reader to feel the emotion without being told. The tanka names the emotion, but names it so precisely that it does not feel like telling. It feels like recognition.
Neither form is better. They do different things. But if you have tried haiku and found them too spare, too much like holding your breath, the tanka might be your form. It gives you room to exhale.
Writing Your First Tanka
Go outside. Or look out a window. Find one thing in the natural world that holds your attention. A cloud, a bird, the way the light hits a wet street. Write three lines about it. Be specific. Do not reach for beauty. Reach for accuracy.
Then ask yourself: what does this remind me of? What does this make me feel? Write two more lines. Do not explain the connection between the image and the feeling. Just put them next to each other. The reader will do the rest.
Here is a practical tip. Write five tanka in one sitting. The first two will probably be stiff. By the third, you will start to relax into the form. By the fifth, you will understand what the pivot feels like, that small shift from looking outward to looking inward.
The tanka is not a difficult form. It is a precise one. It asks you to notice the world and then notice yourself noticing. Five lines. Two breaths. One moment caught between what you see and what you feel.
Try it tonight. The world is full of tanka waiting to be written. You just have to look long enough for the feeling to arrive.
