後で (ato de) means “after (doing)” or, on its own, “later.” It is a JLPT N4 time expression that puts one event after another: 宿題をした後で、テレビを見ます — “I’ll watch TV after I do my homework.”
You already know 後 from N5 words like 午後 and その後. At N4 you learn to hang a whole clause on it, which is how Japanese says “after I eat,” “after class,” or “after the meeting ends.” The one rule that trips everyone up: the verb before 後で is always in the た-form, even when you are talking about the future.
後で marks the point in time after something is finished. The verb before it is past because that action is complete by the time the next one happens.
What does 後で mean?
後 (あと) means “after” or “the time after.” Add the particle で and you get a time phrase: “at the time after X.” The pattern is [finished event] 後で、[next event].
- 授業の後で、先生に質問しました。 — I asked the teacher a question after class.
- ご飯を食べた後で、散歩します。 — I’ll go for a walk after eating.
Used alone, with nothing in front, 後で is an everyday adverb meaning “later”:
- 後で電話します。 — I’ll call you later.
- じゃあ、また後で。 — See you later.
Both uses share the same idea: the second event happens once the first one is over, with no promise about how soon.
How to form 後で
後で attaches to a noun + の or to a verb in the た-form. It does not attach to adjectives.
| Base | Attachment | Result |
|---|---|---|
| 食べる | た-form | 食べた後で |
| 見る | た-form | 見た後で |
| 洗う | た-form | 洗った後で |
| 仕事 | noun + の | 仕事の後で |
| 会議 | noun + の | 会議の後で |
A few nouns work especially well here because they name events: 授業, 会議, 試合, 食事, 仕事, パーティー. A noun that is not an event, like 駅 or 先生, sounds odd: 先生の後で means “after the teacher” in a line, not “after meeting the teacher.”
You will also see 後に (more written, a precise point in time) and bare 後、 (後 + comma, very common in speech): 食べた後、歯を磨きます. At N4, learn 後で first; the others follow the same attachment rules.
When is 後で used?
- Ordering your plans: 仕事の後で、ジムに行きます — the main use in daily conversation.
- Instructions: medicine labels, recipes, and manuals use 〜た後で to say what to do once a step is done: 食べた後で飲んでください.
- Putting something off: 後で alone is how you say “later” when you can’t deal with something right now: 今忙しいから、後で見るね.
- Past narratives: 映画を見た後で、カフェに行きました — the same form works for things that already happened.
後で is neutral. It fits polite speech with です／ます and casual speech equally well; only the main verb at the end changes.
後で example sentences

今ちょっと忙しいので、後で連絡します。

お皿を洗った後で、台所を掃除しました。
After washing the dishes, I cleaned the kitchen.
試合が終わった後で、雨が降り始めた。
It started raining after the game had finished.
Look at the tense in examples 1 and 2: the main verbs (見ます, 飲んでください) point to the future, yet the verb before 後で is した and 食べた. The た there does not mean “in the past”; it means “completed.”
Nuance of 後で
後で is about time order only. It tells you B happens after A, and nothing more. There can be a long gap and unrelated events in between: 大学を卒業した後で、日本に来ました is fine even if you worked in your home country for five years in between.
That neutrality is what separates it from てから. てから suggests that A is a step you finish first, often a prerequisite, and B follows directly. 後で just places B on the timeline.
Also notice that 後で focuses on when B happens. If the sentence is really about what you do before something else, flip it and use 前に: 寝る前に歯を磨く (dictionary form before 前に) vs 食べた後で歯を磨く (た-form before 後で). The two patterns are mirror images, and their verb forms are opposite.
後で vs 後から: 後から also means “later,” but it adds the idea of something coming after the main thing is already under way: 後から行きます — “I’ll join you later (you go ahead).”
後で vs てから
Both put one action after another, and in many plain sequences either works. The differences are in the verb form and in what the speaker is emphasising.
A parent laying down a rule would say 宿題をしてから遊びなさい — homework first, it’s a condition. Only てから can mean “since”: 日本に来てから三年です works, but 来た後で三年です does not. And only 後で works alone as “later.”
Common mistakes with 後で
The verb before 後で must be in the た-form, even for future plans. Dictionary form belongs with 前に.
Nouns need の before 後で. (授業後 without で exists as a compact written word, but 授業後で is wrong.)
To count time since an event (“it’s been three years since…”), use てから. 後で only orders two events.
Is 後で on the JLPT?
Yes. 〜た後で is core N4 grammar. Expect grammar blanks that test the verb form in front of it, and listening tasks where you must put a speaker’s actions in the right order.
At N4 you should be able to:
- Pick the た-form (not the dictionary form) before 後で
- Use noun + の後で with event nouns like 授業 and 会議
- Tell 後で from てから and 前に in sequence questions
A typical question gives 食べ（ ）後で and offers る／た／て／ない. The answer is た. In listening, questions like 「男の人はこの後まず何をしますか」 hinge on catching which action comes before 後で.
