ABOUT
About Haiku and Tanka Mora Counter | Syllable Pattern and Kigo Checker
Count Japanese mora in haiku, senryu, tanka, dodoitsu, sedoka, or free verse. The checker separates small kana combinations, gemination, nasal sounds, and long vowels, then reports line counts, pattern deviations, possible kigo, and line-breaking notes.
How to use Haiku and Tanka Mora Counter | Syllable Pattern and Kigo Checker
- 1Choose a verse form such as haiku, senryu, tanka, or free verse.
- 2Enter the poem in Japanese; add spaces or line breaks where you want the ku boundaries.
- 3Review the generated kana reading and edit it when a word has a special reading.
- 4Check the mora count and notes for extra or missing mora, line breaks, and kireji.
- 5Review possible kigo and season, then copy the result or a shareable URL.
Great for
- Check whether a haiku follows the 5-7-5 mora pattern.
- Review a senryu for an eight-mora middle line (nakahachi).
- Count the 31 mora of a tanka by line.
- Look up likely seasonal words in a poem.
- Teach how small kana, っ, ん, and long vowels count in Japanese verse.
Good to know
- Japanese verse is counted in mora, not by written characters. Small kana combinations such as きゃ count as one mora; っ, ん, and ー each count as one.
- Automatic readings use a dictionary's usual pronunciation. Edit names, place names, and poetic readings when needed.
- When ku boundaries are omitted, the tool estimates them from word boundaries. Add line breaks in the reading field to set them explicitly.
- Kigo are matched against a curated list. Seasonal classifications can vary by saijiki, so confirm uncertain terms in a reference book.
- The checker identifies likely kireji endings such as や, かな, and けり; this is a guide rather than a literary judgment.
- Your poem and reading are stored only in this browser. The reading dictionary also runs locally.

FAQ
- How many mora are きゃ and しゅ?
- Each combination of a kana and a small ゃ, ゅ, or ょ counts as one mora. For example, きゃく is きゃ・く, or two mora.
- Do っ, ん, and ー count as one mora each?
- Yes. A small っ, the nasal ん, and the long-vowel mark ー each count as one mora.
- What is nakahachi?
- It is an eight-mora middle line in a 5-7-5 poem. It can make the rhythm feel uneven, especially in senryu.
- Are extra mora always wrong?
- No. Extra mora are used in many celebrated poems. The checker reports the pattern so you can decide whether the deviation is intentional.
- What is kumatagari?
- Kumatagari occurs when a word or phrase crosses a ku boundary, even when the total mora still match the form.
- What does kigo overlap mean?
- It means that two or more seasonal terms may appear in one poem. It is not automatically an error, but the seasonal focus may be worth reviewing.
- Why are morning glory and Tanabata classified as autumn kigo?
- Traditional kigo seasons follow the old lunar calendar. Some plants and events that occur in summer by today's calendar are classified as autumn in haiku.
- What if the automatic kanji reading is wrong?
- Edit the reading field in hiragana. Use spaces between words and line breaks between ku. The edited reading stays until you change the poem or request a new automatic reading.
