Japanese Relative Clauses: Modifying Nouns
In English we say: “the person who wears glasses,” “the book that I bought yesterday,” “that restaurant which is famous.” Words like “who/that/which” bridge the description and the noun.
In Japanese, that bridge is not written. The pattern is more direct:
[explanatory clause in plain form] + [noun]
This is the relative clause, or 連体修飾. Once you master it, Japanese reading ability jumps, because the structure shows up everywhere: news articles, JLPT items, drama subtitles, even work email.
1. Core idea: put the clause before the noun
Main formula
Clause (plain form) + noun
No “who/that,” no change to the noun itself.
| English | Japanese |
|---|---|
| the book I bought | 私が買った本 |
| the person who lives in Osaka | 大阪に住んでいる人 |
| the movie I watched yesterday | 昨日見た映画 |
Why plain form is required
A relative clause works like an “internal description” glued straight onto the noun. The polite です/ます forms are usually not used inside this clause.
Examples:
Correct: 昨日読んだ本
Incorrect: 昨日読みました本
2. Relative-clause patterns by predicate type
2a. With verbs
| Time | Pattern | Example |
|---|---|---|
| Non-past | V-dictionary + N | 毎日使う辞書 |
| Past | V-ta + N | 昨日買った本 |
| Negative | V-nai + N | 肉を食べない人 |
| Progressive | V-te iru + N | 駅で待っている友達 |
Example 1
私が作った料理を食べてください。
(Watashi ga tsukutta ryouri o tabete kudasai.)
Please eat the dish I made.
Example 2
昨日会った人は高校の友達です。
(Kinou atta hito wa koukou no tomodachi desu.)
The person I met yesterday is a high-school friend.
2b. With i-adjectives
Pattern: i-adjective directly + noun.
Example 3
安い店を探しています。
(Yasui mise o sagashite imasu.)
I’m looking for a cheap shop.
Example 4
面白い映画が見たいです。
(Omoshiroi eiga ga mitai desu.)
I want to watch an interesting movie.
2c. With na-adjectives and nouns
Pattern: na-adjective + な + noun or noun + の + noun.
Example 5
静かな場所で勉強したい。
(Shizuka na basho de benkyou shitai.)
I want to study in a quiet place.
Example 6
日本の会社で働く友達がいます。
(Nihon no kaisha de hataraku tomodachi ga imasu.)
I have a friend who works at a Japanese company.
3. Who is the subject inside the clause?
Inside a relative clause, the subject particle is often が, though は can appear depending on focus.
| Pattern | Nuance |
|---|---|
X が V-た N | X is the subject of the action in the clause |
X は V-た N | adds contrast or a specific topic |
Example 7
私が好きな歌
(Watashi ga suki na uta)
The song I like
Example 8
彼が書いた記事
(Kare ga kaita kiji)
The article he wrote
4. Long relative clauses (embedded clauses)
This is the part that often confuses learners. Key move: find the core noun at the right end first, then read leftward for its description.
Example 9
去年京都で撮った写真を母に見せました。
(Kyonen Kyoto de totta shashin o haha ni misemashita.)
I showed my mother the photo I took in Kyoto last year.
Example 10
私が子どもの頃に住んでいた町は海の近くでした。
(Watashi ga kodomo no koro ni sunde ita machi wa umi no chikaku deshita.)
The town where I lived as a child was near the sea.
Example 11
駅の前で赤いかばんを持って立っている人が田中さんです。
(Eki no mae de akai kaban o motte tatte iru hito ga Tanaka-san desu.)
The person standing in front of the station holding a red bag is Tanaka-san.
Fast-reading technique for long clauses
- Find the rightmost main noun (
人,写真,町, etc.). - Mark everything to its left as the description.
- Rebuild the English sense with “who/that/which…”.
5. Time and situation patterns you see often
| Pattern | Meaning | Example |
|---|---|---|
| V-た + 時 | when / after doing | 家に帰った時 |
| V-る + 前 | before doing | 寝る前 |
| V-た + 後 | after doing | 食べた後 |
| V-る + 予定 | plan to do | 出発する予定 |
Example 12
授業が終わった後で、カフェに行きました。
(Jugyou ga owatta ato de, kafe ni ikimashita.)
After class finished, I went to a café.
6. Important comparisons
6a. Relative clause vs two separate sentences
| Form | Feel |
|---|---|
| 昨日買った本 | compact, natural in writing and speech |
| 本です。昨日買いました。 | choppy, feels like two separate statements |
6b. Relative clause vs simple の
の marks possession or category: 日本の本.
A relative clause marks action or condition: 昨日買った本.
7. Mini dialogues
Dialogue 1: Looking for an apartment
A: 静かな場所で、駅に近い部屋を探しています。
(Shizuka na basho de, eki ni chikai heya o sagashite imasu.)
I’m looking for a quiet room near the station.
B: じゃあ、先週見た物件がいいかもしれません。
(Jaa, senshuu mita bukken ga ii kamo shiremasen.)
Then the listing I saw last week might work.
A: 家賃が安い部屋ですか。
(Yachin ga yasui heya desu ka.)
Is it a room with cheap rent?
B: はい、新しくて広い部屋です。
(Hai, atarashikute hiroi heya desu.)
Yes, it’s a new, spacious room.
Dialogue 2: Class presentation
Teacher: 今日は自分が読んだ記事について話してください。
(Kyou wa jibun ga yonda kiji ni tsuite hanashite kudasai.)
Today, please talk about an article you read.
Student: 私が選んだのは、外国人が住みやすい町についての記事です。
(Watashi ga eranda no wa, gaikokujin ga sumiyasui machi ni tsuite no kiji desu.)
What I chose is an article about towns that are easy for foreigners to live in.
8. Common mistakes ⚠️
| ❌ Wrong | ✅ Right | Note |
|---|---|---|
| 買いました本 | 買った本 | Relative clauses use plain form, not ます |
| 静か場所 | 静かな場所 | Na-adjectives need な before a noun |
| 日本本 | 日本の本 | Noun modifiers need の |
| 昨日買ったは本 | 昨日買った本 | Don’t insert は between clause and noun |
| 食べるない人 | 食べない人 | Wrong negative form |
| 赤いの車 (for an action clause) | 昨日買った車 | の is not a stand-in for an action clause |

10. Fast-reading strategy for long texts
On the way from N4 to N3, reading items often stack relative clauses. Word-by-word left-to-right reading gets you lost. Use this strategy.
Step 1: Find the core noun
Look at the rightmost noun first. That is the core being described.
Example:
先月日本から帰国した姉が作った料理
(Sengetsu Nihon kara kikoku shita ane ga tsukutta ryouri)
The dish my older sister, who returned from Japan last month, made
The core noun here is 料理.
Step 2: Group the clause into meaning blocks
Break the sentence into:
- 先月日本から帰国した姉
- その姉が作った
- 料理
This way your brain processes structure, not only word order.
Step 3: Rebuild with English “who/that”
Early practice benefits from this bridge:
- Japanese: 駅の近くにある静かな店
- English: a quiet shop that is near the station
Once you’re used to it, full translation is no longer required.
Step 4: Separate required info from optional detail
In some sentences the relative clause adds extra detail, not the main message.
Example 1
昨日読んだ記事は少し難しかった。
(Kinou yonda kiji wa sukoshi muzukashikatta.)
The article I read yesterday was a bit hard.
Core message: the article was hard. “that I read yesterday” only identifies which article.
11. Sentence production: from short to nested
Beyond reading comprehension, train production in stages.
Stage A: One clause + one noun
- 私が買った本
- 友達が働いている会社
Stage B: Add time or place detail
- 昨日駅前で買った本
- 大阪で働いている友達
Stage C: Combine two clauses
先週会った先生が紹介してくれた本
(Senshuu atta sensei ga shoukai shite kureta hon)
The book recommended by the teacher I met last week
Stage D: Full sentence
先週会った先生が紹介してくれた本を、昨日全部読みました。
(Senshuu atta sensei ga shoukai shite kureta hon o, kinou zenbu yomimashita.)
I finished the book recommended by the teacher I met last week.
Weekly practice target
- Days 1–2: 10 Stage A sentences.
- Days 3–4: 10 Stage B sentences.
- Days 5–6: 10 Stage C sentences.
- Day 7: 5 Stage D sentences.
With this pattern you don’t only “know the theory”—you can produce long relative clauses without scrambling word order.
12. Quick error-correction drill
One of the fastest ways to master relative clauses is correction practice. Below are error types that show up constantly for learners.
Type 1: Still using ます
❌ 昨日見ました映画
✅ 昨日見た映画
Reason: relative clauses require plain form.
Type 2: Missing な on a na-adjective
❌ 静か場所
✅ 静かな場所
Type 3: Missing の on a noun modifier
❌ 日本会社
✅ 日本の会社
Type 4: Putting particle は in the middle
❌ 昨日買ったは本
✅ 昨日買った本
Type 5: Reversed information order
❌ 本、私が昨日買った
✅ 私が昨日買った本
These look small, yet they decide how natural the sentence feels.
5-minute practice method
- Write 5 wrong sentences on purpose.
- Correct them yourself without notes.
- Read the corrected versions aloud.
- Repeat tomorrow with a different topic.
A consistent week of this makes relative structures much easier to spot in long reading.
13. Checklist before you submit writing
When you write an essay or exam answer, run this quick check:
- Are all relative clauses already in plain form (no
ます)? - Do na-adjectives already use
なbefore the noun? - Do noun modifiers already use
のwhen needed? - Is the core noun at the right end of the clause?
- Is any
はstuck between modifier and noun?
Mini revision example
First draft:
私が先週見ました映画は面白かった。
Correct revision:
私が先週見た映画は面白かった。
Tiny fixes like this strongly affect grammar scores and naturalness.
14. Super-short recap
Hold these three golden rules:
- The relative clause always comes before the noun.
- The predicate inside the clause uses plain form.
- Na-adjectives take
な; noun modifiers takeの.
Final examples:
- 昨日買った本
- 静かな部屋
- 日本の会社
When these three patterns are automatic, long N3 texts feel much lighter.
For a final drill, take one short paragraph from a simple Japanese article and underline every noun. Find which ones are modified by a clause. This trains your eye to see relative structure automatically while reading.
Keep rewriting two sentences of your own every day. That small habit makes relative structure feel far more natural. The more you repeat it, the faster your eye catches the pattern in reading.

Conclusion
- Japanese relative clauses put the description first and the noun after.
- There is no written “who/that,” yet the meaning is still there.
- Every relative clause uses plain form.
- The key to long clauses is finding the core noun at the right end.
- Mastering this pattern is essential for moving from short sentences to N3-level text.
After this, you will be better prepared for more complex topics such as the passive, the causative, and advanced compound-sentence structures.
