Japanese haiku app with AI ・ AI俳句アプリ
Write Japanese haiku,
with an AI buddy and the sounds of the season.
Haiku Club (俳句くらぶ) is a Japanese haiku app made in Japan. Write haiku in Japanese while talking them over with Kusuke (句助), your AI haiku buddy, then finish them as irodori haiku (彩り俳句) with a background scene and the sounds of the season. For haiku lovers around the world, learners of Japanese, and anyone whose life touches Japan.
Available on the App Store and Google Play. Write haiku, talk with Kusuke, and make irodori haiku without signing up (free to download, in-app purchases available). The app screens and Kusuke’s replies are currently in Japanese, and you write your haiku in Japanese.
What is Haiku Club (俳句くらぶ)?
Fitting a moment into 5-7-5 (五・七・五) is harder than it looks. Haiku Club gives you an AI buddy to talk with, scenes and sounds to color your work, and a small gathering to share it — a kukai (句会) — supporting you from writing a haiku to enjoying it with others. It is about the original form: Japanese haiku with kigo (季語, season words), not English haiku.
Talk it over with Kusuke
Kusuke, your AI buddy, looks for the right words with you through questions and replies. You don’t have to struggle alone — polish your haiku until you are happy with it.
Add a scene and sounds
Add a background scene and ambient sounds to your haiku to make an irodori haiku (彩り俳句). Seventeen sounds on paper become a work you can enjoy with your eyes and ears.
Hold a kukai with friends
Open a small kukai (句会, haiku gathering) with an invite code. Write on a shared theme, choose each other’s favorites, and keep them in an anthology.
Four steps to a finished haiku
Find 見つける
Keep the seasons you notice in daily life as “haiku seeds”: notes, photos, and voice. Going for a walk? Ginkō (吟行) mode gathers what you collect into one record for the day.
Write つくる
Type, speak, or take a photo of a haiku you wrote by hand — even if you are still learning to write Japanese. Polish it while talking with Kusuke.
Color 彩る
Add a background scene and ambient sounds to make an irodori haiku. AI can also draw the scene for you.
Enjoy 楽しむ
Your works collect in your haiku notebook (俳句帳). Submit them to a kukai, or gather them into an anthology (句集) and print it.
Ginkō (吟行): collect seeds as you walk
Keep the scenes and sounds that catch your eye on a walk or a trip, right where you are. You can shape them into haiku once you get home — no pressure to write a perfect poem on the spot.
What you see and hear, right there
Write, speak, or take a photo
Tap “Start ginkō” and just walk. Note down what moves you by writing, speaking, or photographing text on paper. Recording sounds and taking photos of the scenery are on the same screen, too.
- What you collect is kept as “haiku seeds”
- When you finish, Kusuke looks back on the walk with you
- No location data is used (name places in your own words)
The path you walked that day, kept
Organized by when and where you walked
Everything you collect is grouped by each day’s ginkō. Give it a name like “To the shopping street” or “Morning at the shrine,” and the feeling of that day comes back when you read it again.
- Keep as many seeds as you like on one walk
- You can name it later
- Your ginkō continues even if you leave the screen
Kusuke is a buddy, not a teacher
Kusuke doesn’t grade or correct your haiku. It thinks with you through questions and replies, keeping your own words at the center.
Questions that draw out your words
One question at a time, toward a haiku
“What kind of seasonal scene was it?” — Kusuke asks one question at a time and grows a haiku from your answers. It never writes the poem for you; the words stay yours.
- Ask about kigo and other wordings
- Revise as many times as you like
- Pick from suggested replies when you’re unsure
Finish your work with scenes and sounds
Enjoy seventeen sounds with eyes and ears
Choose a background from seasonal photos and add ambient sounds, and the scene of your haiku comes to life. If you can’t find the scene you imagined, AI can draw it for you.
- Choose a background from seasonal scenes
- Add ambient sounds such as insects or rain
- AI can generate a background
Write your way
No need to type small letters. You can write by voice, or from a photo of a haiku written on paper.
Read handwriting
Take a photo of a haiku written on paper, and it is read in as text — great for practicing handwriting in Japanese.
Speak
Say the seventeen sounds that come to mind, and they are written down.
Type
On a large keyboard, at your own pace.
Write with Kusuke
Just answer the questions, and a haiku takes shape.

A year of haiku becomes a book
Laid out like tanzaku (短冊) poem cards
Scroll to the bottom of your irodori haiku list to find My Anthology (私の句集): pages laid out as tanzaku cards, in order of spring, summer, autumn, and winter. Mark favorites as “Tottoki” (とっておき, treasured) to make a book of just those haiku.

Overview
Frequently asked questions
Can I use it if I’ve never written a haiku?
Yes. Kusuke draws out your words with questions like “What was the scene like?”, so your haiku comes together even if you don’t know the rules of 5-7-5 well. Rather than aiming for a perfect poem, it is enough to start by keeping the moments when you felt the season.
Can I try it without signing up?
You can write haiku, talk with Kusuke, and make irodori haiku without an account. To join a kukai, please create a free account.
Is a haiku made with Kusuke really my own work?
Kusuke doesn’t write haiku for you; it helps with questions and alternative wordings. You choose the final words, so the finished haiku is your work. AI suggestions may contain mistakes, such as in the use of kigo. If something seems off, try other wordings and check.
I find small text hard to read. Will that be a problem?
You can choose from three text sizes and three high-contrast color themes. Buttons are large, and ads are never placed within the screen (on the free plan, ads appear between steps).
Can I keep using it for free?
Yes. The main features are available on the free plan (with limits on storage and usage, and ads between steps). For everyday use, please consider the ad-free Basic plan.
Does it need an internet connection?
An internet connection is needed for talking with Kusuke, handwriting recognition, voice input, and AI background generation.
