Writing in Japanese is a different challenge from reading, speaking, or listening. When you write, every grammar mistake is visible, every wrong kanji is permanent, and you can’t rely on context or gestures to fill gaps. But writing is also the fastest way to solidify your Japanese — it forces precision that other skills don’t.
This guide covers Japanese composition (作文, さくぶん, sakubun) from the ground up: the unique essay structure, essential transition words, formal vs. casual writing, common mistakes, and daily practice methods.
Japanese Essay Structure: 起承転結 (Kishoutenketsu)
While Western essays follow a thesis-evidence-conclusion structure, traditional Japanese writing uses a four-part structure called 起承転結 (きしょうてんけつ, kishoutenketsu):
| Part | Kanji | Reading | Role | Western Equivalent |
|---|---|---|---|---|
| 1 | 起 | き (ki) | Introduction — present the topic | Introduction |
| 2 | 承 | しょう (shou) | Development — expand on the topic | Body (supporting) |
| 3 | 転 | てん (ten) | Twist — a new angle or counterpoint | No direct equivalent |
| 4 | 結 | けつ (ketsu) | Conclusion — wrap up and reflect | Conclusion |
The 転 (ten) is what makes Japanese writing unique. Instead of only supporting your initial point, you introduce an unexpected perspective, contrasting opinion, or twist. This creates depth and shows critical thinking. Even in academic writing, Japanese essays often acknowledge complexity rather than driving toward a single forceful conclusion.
Kishoutenketsu in Practice: Example Essay
Topic: 携帯電話は便利だ (Smartphones are convenient)
起 (Introduction):
現代社会において、携帯電話は欠かせない存在となっている。
(Gendai shakai ni oite, keitai denwa wa kakasenai sonzai to natte iru.)
“In modern society, mobile phones have become an indispensable presence.”
承 (Development):
携帯電話のおかげで、いつでもどこでも情報を得ることができる。また、遠い場所にいる家族や友人とも簡単に連絡を取ることができるようになった。
(Keitai denwa no okage de, itsudemo dokodemo jouhou wo eru koto ga dekiru. Mata, tooi basho ni iru kazoku ya yuujin to mo kantan ni renraku wo toru koto ga dekiru you ni natta.)
“Thanks to mobile phones, we can get information anytime, anywhere. Also, we can easily contact family and friends who are far away.”
転 (Twist):
しかし一方で、携帯電話への依存が深刻な問題になっている。歩きスマホによる事故や、SNS中毒による精神的な影響も報告されている。
(Shikashi ippou de, keitai denwa e no izon ga shinkoku na mondai ni natte iru. Aruki-sumaho ni yoru jiko ya, SNS chuudoku ni yoru seishin-teki na eikyou mo houkoku sarete iru.)
“However, on the other hand, dependence on mobile phones has become a serious problem. Accidents from walking while using phones and mental health effects from SNS addiction have been reported.”
結 (Conclusion):
携帯電話は非常に便利な道具であるが、使い方を意識することが大切だと考える。
(Keitai denwa wa hijou ni benri na dougu de aru ga, tsukaikata wo ishiki suru koto ga taisetsu da to kangaeru.)
“Mobile phones are extremely convenient tools, but I believe it is important to be mindful of how we use them.”
Paragraph Structure in Japanese
Japanese paragraphs have their own conventions:
- Indent one character space (一字下げ, ichiji sage) at the start of each paragraph
- One idea per paragraph — same as English
- Topic sentence first — state the main point, then elaborate
- Connect paragraphs with transition words (接続詞)
Essential Transition Words (接続詞, setsuzokushi)
Transition words are the glue of Japanese writing. Without them, your writing feels choppy and disconnected. Here are the most important ones:
Adding Information
| Japanese | Reading | English | Usage |
|---|---|---|---|
| また | mata | Also / Furthermore | Adding another point |
| さらに | sarani | Moreover / In addition | Strengthening the point |
| そのうえ | sono ue | On top of that | Adding emphasis |
| それに | sore ni | Besides / What’s more | Casual addition |
| 加えて | kuwaete | In addition to | Formal addition |
Contrasting
| Japanese | Reading | English | Usage |
|---|---|---|---|
| しかし | shikashi | However | Standard contrast |
| 一方で | ippou de | On the other hand | Presenting another side |
| ところが | tokoro ga | However (unexpected) | Surprising contrast |
| それに対して | sore ni taishite | In contrast to that | Direct comparison |
| むしろ | mushiro | Rather / On the contrary | Correcting a misunderstanding |
Cause and Effect
| Japanese | Reading | English | Usage |
|---|---|---|---|
| そのため | sono tame | For that reason / Therefore | Explaining result |
| したがって | shitagatte | Consequently | Formal conclusion |
| その結果 | sono kekka | As a result | Stating outcome |
| なぜなら | nazenara | That is because | Explaining reason |
| 〜からだ | ~ kara da | It is because ~ | Sentence-final reason |
Concluding
| Japanese | Reading | English | Usage |
|---|---|---|---|
| つまり | tsumari | In other words / In short | Summarizing |
| 以上のことから | ijou no koto kara | From the above | Drawing conclusion from evidence |
| 結論として | ketsuron toshite | In conclusion | Formal conclusion |
| このように | kono you ni | In this way / Thus | Wrapping up |
| 要するに | you suru ni | To put it simply | Simplifying |
Formal vs. Casual Writing Styles
Japanese has two main writing styles, and mixing them is a serious mistake. Choose one and maintain it throughout:
| Feature | 丁寧体 (Polite/です・ます style) | 常体 (Plain/だ・である style) |
|---|---|---|
| Sentence ending | 〜です、〜ます | 〜だ、〜である |
| Negative | 〜ません | 〜ない |
| Past tense | 〜ました | 〜た |
| Used in | Letters, business emails, blog posts | Essays, academic papers, newspaper editorials |
| Feels | Polite, warm, personal | Objective, authoritative, impersonal |
| JLPT composition | Either is acceptable, but be consistent | More common for argumentative essays |
Example comparison:
Polite (です/ます):
日本語の勉強は楽しいです。毎日少しずつ上達しています。
(Nihongo no benkyou wa tanoshii desu. Mainichi sukoshi zutsu joutatsu shite imasu.)
“Studying Japanese is fun. I’m improving little by little every day.”
Plain (だ/である):
日本語の勉強は楽しい。毎日少しずつ上達している。
(Nihongo no benkyou wa tanoshii. Mainichi sukoshi zutsu joutatsu shite iru.)
“Studying Japanese is fun. I improve little by little every day.”
Common Writing Mistakes by English Speakers
These errors are so common among English-speaking learners that Japanese teachers can spot a non-native writer instantly:
Mistake 1: Over-Using 私は (watashi wa)
English-style:
私は学生です。私は東京に住んでいます。私は日本語を勉強しています。
Natural Japanese:
学生です。東京に住んでいて、日本語を勉強しています。
Japanese drops the subject when it’s obvious. Starting every sentence with 私は sounds repetitive and unnatural.
Mistake 2: Sentences Too Long
One massive sentence:
昨日友達と渋谷に行って、映画を見て、その後レストランでご飯を食べて、電車で帰りました。
Natural paragraph:
昨日、友達と渋谷に行った。映画を見た後、近くのレストランでご飯を食べた。楽しい一日だった。
Break long sentences into shorter ones. Japanese favors clarity over complexity.
Mistake 3: Direct Translation of English Idioms
時間を殺す (jikan wo korosu, “kill time”) — This doesn’t exist in Japanese
暇をつぶす (hima wo tsubusu, “crush free time”) — The actual Japanese expression
足を引っ張る... wait, this one actually works! (ashi wo hipparu = hold someone back)
But most English idioms do NOT translate directly. Use Japanese-specific expressions.
Mistake 4: Mixing Formal and Casual Styles
Mixed:
この問題は深刻である。解決策を考えなければなりません。
(である style switches to ます style mid-paragraph)
Consistent (plain):
この問題は深刻である。解決策を考えなければならない。
Mistake 5: Forgetting て-form Connections
In Japanese, you connect related actions within a sentence using the て-form, not separate sentences:
Choppy: 起きました。顔を洗いました。朝ご飯を食べました。
Connected: 起きて、顔を洗って、朝ご飯を食べた。
(Okite, kao wo aratte, asagohan wo tabeta.)
“I woke up, washed my face, and ate breakfast.”
Japanese Letter Writing (手紙の書き方)
Formal Japanese letters have a specific structure that’s quite different from English letters:
Formal Letter Structure
| Part | Japanese Term | Content |
|---|---|---|
| 1. Opening greeting | 頭語 (とうご, tougo) | 拝啓 (haikei, “Dear...”) |
| 2. Seasonal greeting | 時候の挨拶 (jikou no aisatsu) | Mention the current season |
| 3. Health inquiry | 安否の挨拶 (anpi no aisatsu) | Ask about wellbeing |
| 4. Main content | 本文 (honbun) | The purpose of the letter |
| 5. Closing greeting | 結びの挨拶 (musubi no aisatsu) | Wish for good health |
| 6. Closing word | 結語 (けつご, ketsugo) | 敬具 (keigu, “Sincerely”) |
| 7. Date | 日付 (hiduke) | Year, month, day |
| 8. Sender name | 差出人 (sashidashinin) | Your name |
| 9. Recipient name | 宛名 (atena) | Recipient’s name + 様 |
Seasonal Greetings by Month
| Month | Greeting | Reading |
|---|---|---|
| January | 新春の候 | しんしゅんのこう (shinshin no kou) |
| April | 桜花の候 | おうかのこう (ouka no kou) |
| July | 盛夏の候 | せいかのこう (seika no kou) |
| October | 秋涼の候 | しゅうりょうのこう (shuuryou no kou) |
| December | 師走の候 | しわすのこう (shiwasu no kou) |
Example formal letter opening:
拝啓 桜花の候、ますますご健勝のこととお慶び申し上げます。
(Haikei. Ouka no kou, masumasu gokenshou no koto to oyorokobi moushiagemasu.)
“Dear [recipient], in this season of cherry blossoms, I am delighted to hear that you are in good health.”

Daily Writing Practice Methods
Method 1: Journaling (日記, nikki)
The simplest and most effective daily practice. Write 3–5 sentences about your day.
Beginner journal entry:
今日は天気が良かった。午前中に買い物に行った。午後は日本語を勉強した。夜はカレーを作って食べた。
(Kyou wa tenki ga yokatta. Gozenchu ni kaimono ni itta. Gogo wa nihongo wo benkyou shita. Yoru wa karee wo tsukutte tabeta.)
“The weather was nice today. I went shopping in the morning. I studied Japanese in the afternoon. In the evening, I made and ate curry.”
Intermediate journal entry (with opinions):
今日、新しいカフェに行ってみた。店の雰囲気はとても良かったが、コーヒーの値段が少し高いと思った。でも、また行きたい。静かで勉強に集中できる場所だった。
(Kyou, atarashii kafe ni itte mita. Mise no fun’iki wa totemo yokatta ga, koohii no nedan ga sukoshi takai to omotta. Demo, mata ikitai. Shizuka de benkyou ni shuuchuu dekiru basho datta.)
“Today I tried going to a new cafe. The atmosphere was great, but I thought the coffee price was a bit high. But I want to go again. It was a quiet place where I could concentrate on studying.”
Method 2: Describe a Photo
Pick a random photo from your camera roll and describe it in 3–5 Japanese sentences. This builds descriptive vocabulary.
Method 3: Summarize What You Read
After reading a Japanese article or book passage, write a 2–3 sentence summary in Japanese. This combines reading comprehension with writing output.
Method 4: Opinion Writing
Write a short opinion paragraph on a topic. Use this pattern:
Pattern:
[Topic]について、私は[opinion]と考える。なぜなら、[reason 1]からだ。また、[reason 2]も挙げられる。したがって、[conclusion]。
Example:
オンライン学習について、私は非常に効果的だと考える。なぜなら、自分のペースで学べるからだ。また、通学時間を節約できる点も挙げられる。したがって、オンライン学習はこれからの教育に不可欠である。
(Onrain gakushuu ni tsuite, watashi wa hijou ni kouka-teki da to kangaeru. Nazenara, jibun no peesu de manaberu kara da. Mata, tsuugaku jikan wo setsuyaku dekiru ten mo agerareru. Shitagatte, onrain gakushuu wa kore kara no kyouiku ni fukaketsu de aru.)
“Regarding online learning, I think it is very effective. This is because you can learn at your own pace. Additionally, the point that you can save commuting time can also be raised. Therefore, online learning is essential for education going forward.”

Useful Sentence-Ending Expressions for Essays
How you end sentences affects the tone of your entire essay:
| Expression | Reading | Meaning | Register |
|---|---|---|---|
| 〜と考える | ~ to kangaeru | I think that ~ | Formal (academic) |
| 〜と思われる | ~ to omowareru | It is thought that ~ | Formal (objective) |
| 〜ではないだろうか | ~ de wa nai darou ka | Isn’t it the case that ~? | Formal (rhetorical) |
| 〜と言える | ~ to ieru | It can be said that ~ | Formal (assertive) |
| 〜べきだ | ~ beki da | Should / ought to ~ | Formal (strong opinion) |
| 〜必要がある | ~ hitsuyou ga aru | There is a need to ~ | Formal (recommendation) |
| 〜に違いない | ~ ni chigai nai | Without a doubt ~ | Formal (certainty) |
Writing for the JLPT
While the JLPT doesn’t have a dedicated writing section, composition skills help in multiple areas:
- Reading comprehension: Understanding essay structure helps you predict logical flow in reading passages
- Grammar: Writing practice reinforces grammar patterns tested on the exam
- Vocabulary: Active writing embeds vocabulary more deeply than passive recognition
JLPT reading strategy tip: Many JLPT reading passages follow 起承転結 structure. When you reach the 転 section (usually signaled by しかし, ところが, or 一方で), pay close attention — the answer to comprehension questions often comes from how the author handles the twist.
Building Blocks: Useful Sentence Patterns
These patterns appear constantly in Japanese composition and are essential building blocks:
| Pattern | Meaning | Example |
|---|---|---|
| 〜において | In / at (formal) | 現代社会において (gendai shakai ni oite — “in modern society”) |
| 〜に関して | Regarding / concerning | 環境問題に関して (kankyou mondai ni kanshite — “regarding environmental issues”) |
| 〜を通じて | Through / via | 経験を通じて (keiken wo tsuujite — “through experience”) |
| 〜にとって | For (someone) | 学生にとって (gakusei ni totte — “for students”) |
| 〜だけでなく | Not only ~ but also | 便利なだけでなく (benri na dake de naku — “not only convenient but also”) |
| 〜一方で | While / on the other hand | 増加する一方で (zouka suru ippou de — “while increasing”) |

Frequently Asked Questions
起承転結 is the traditional Japanese four-part essay structure: 起 introduces the topic, 承 develops it, 転 provides a twist or new perspective, and 結 concludes. Unlike Western essays that argue a thesis from start to finish, kishoutenketsu introduces an unexpected turn (転) that adds depth and nuance.
The easiest daily practice is journaling (日記). Write 3–5 sentences about your day in Japanese. Start with simple past tense, then gradually add opinions and feelings. Other methods include writing social media posts in Japanese, describing photos, or summarizing articles. Consistency matters more than length — 5 minutes daily beats 1 hour weekly.
The biggest mistakes are: 1) Over-using 私は at the start of every sentence. 2) Writing sentences that are too long. 3) Direct translation of English idioms. 4) Mixing formal (です/ます) and casual (だ/である) styles. 5) Not using connecting words (接続詞) between paragraphs.
