Relative clauses: leave a role open
Japanese puts a complete-looking scene directly before a noun—without “who,” “that,” or “which.” The noun fills one open role inside that scene.
The mental model: scene with a gap → noun
私は昨日、その人に会いました。
I met that person yesterday.
私が昨日［ ］会った人
the person I met yesterday
Build the scene first: 私が昨日［ ］会った. The following noun 人 fills the open に-role. Because the noun itself supplies that participant, Japanese does not insert a relative pronoun or repeat the missing particle.
The head noun can fill different roles
| Phrase | Open role |
|---|---|
| ［ ］私を手伝ってくれた人 | が: the person helped me |
| 私が［ ］読んでいる本 | を: I am reading the book |
| 去年［ ］泊まったホテル | に: I stayed at the hotel |
| 会議を［ ］した部屋 | で: we held the meeting in the room |
Do not decide the relationship from English word order. Reconstruct the ordinary sentence and ask which particle would mark the head noun. The Japan Foundation’s V＋N notes show the same clause-before-noun pattern with subjects, objects, places, and times.
Inside the clause, use the plain form
これから読む本 · 今読んでいる本 · 昨日読んだ本 · まだ読んでいない本
The clause chooses its own time and aspect. It does not inherit them from the main sentence:
来週会う人に、昨日メールを送りました。
Yesterday I emailed the person I will meet next week.
先週会った人と、明日また会います。
Tomorrow I will meet again with the person I met last week.
This also recycles lesson 0003: 窓のそばに座っている人 describes the situation currently holding for the person.
は usually becomes が inside
私はこの本を書きました。
→ これは私が書いた本です。
The whole phrase can be the sentence topic, while the smaller scene has its own subject. This is lesson 0001 at two levels: これ frames the main message; 私が書いた identifies the book inside the modifier. Contrastive は can occur inside a modifier, but plain が is the safe default for its local subject.
The doubled-participant trap
△ 昨日その人に会った人にメールしました。
○ 昨日会った人にメールしました。
If you mean “I emailed the person I met yesterday,” do not put その人に inside the clause. It fills the meeting partner’s role already, leaving the following 人 to be interpreted as another participant. Keep one role open, then let the head noun fill it.
30–60 second retrieval drill
Say all three before revealing. Name the hidden particle each head noun replaces.
- Combine: 先週このカフェに行きました。カフェは静かでした。
- Say: “the person who helped me yesterday.”
- Say: “I’m using the computer Tanaka lent me.”
- 先週行ったカフェは静かでした。（に）
- 昨日私を手伝ってくれた人 （が）
- 田中さんが貸してくれたパソコンを使っています。（を）
Check that each scene has exactly one open role and sits immediately before its noun.
Mental hook: Build the scene, leave one role open, then name it.
