〜てくれる vs. 〜てもらう
The helpful action can be identical. Japanese makes you choose whose side of the exchange holds the camera.
The mental model: one favor, two camera positions
田中さんが駅まで送ってくれました。
Tanaka kindly drove me to the station.
私は田中さんに駅まで送ってもらいました。
I had Tanaka drive me to the station / received the ride from Tanaka.
The ride is the same. 〜てくれる keeps the giver as subject and shows the action coming toward me or my side. 〜てもらう keeps the recipient as subject and presents the action as something received or arranged.
Track the subject, not the English translation
| Camera | Pattern | Natural example |
|---|---|---|
| Helpful actor | 人が Vてくれる | 同僚が説明してくれた。 |
| Recipient / beneficiary | （私は）人に Vてもらう | 同僚に説明してもらった。 |
This reuses lesson 0001’s information camera: with くれる, the helpful actor is commonly marked by が; with もらう, that actor moves to に. The recipient is often omitted when it is obviously the speaker.
The nuance is more than “did”
中田さんが宿題を手伝いました。
Nakata helped with the homework: neutral report.
中田さんが宿題を手伝ってくれました。
Nakata helped us/me: the action is viewed as beneficial.
中田さんに宿題を手伝ってもらいました。
I got Nakata to help / received Nakata’s help.
The Japan Foundation describes 〜てくれる as an action benefiting the receiver, while 〜てもらう can foreground the recipient’s request or arrangement. Do not force “kindly” or “had someone” into every English translation; those are clues to viewpoint, not fixed definitions.
The 〜てあげる trap
〜てあげる points a beneficial action outward from the actor to someone else. It is natural when that favor-framing belongs in the conversation:
母が子どもに本を読んであげた。
The mother read a book for the child.
But saying 先生に説明してあげました can sound as though you are announcing the favor you bestowed on your teacher. Usually report the action neutrally:
先生に説明しました。／先生にご説明しました。
Tokyo University of Foreign Studies likewise cautions that 〜てあげる may imply doing the listener a favor, so social direction matters as much as grammar.
30–60 second retrieval drill
Choose the camera that matches the situation. Say the whole sentence before clicking.
1. A colleague noticed your Japanese mistake and fixed it without being asked. Keep the colleague as the subject.
同僚が日本語を＿＿。
直してくれた: the colleague is the helpful actor.
2. You asked a friend to look over your draft. Keep your received help as the frame.
友だちに原稿を＿＿。
見てもらった: you received or arranged the review.
3. Say both versions of: “Yamada explained the system to me.” First keep Yamada as the camera; then keep yourself as the camera.
山田さんがシステムを説明してくれました。
山田さんにシステムを説明してもらいました。
Mental hook: same helpful event; who holds the camera, and which way does the help flow?
