〜あとで: Saying 'After' (Doing Something) in Japanese
The link it makes: one thing, then the next
あとで is a temporal connector: it places the main action after an earlier action or event. Whatever finishes first goes in front of あとで, and the main clause follows. It is a sequence link, not a cause or contrast one — it says nothing about why things happen, only about when, loosely stacking one event after another on the timeline.
- 食べたあとで → after eating (comes first: eating)
- 授業のあとで → after class (comes first: class)
Tone and register: neutral, and "later" on its own
あとで sits comfortably in both casual and polite sentences — it carries no particular formality of its own, so the register comes from the verb ending you attach it to (散歩する vs 散歩します). Standing alone, without a preceding clause, あとで shrinks to a plain adverb meaning "later" — the kind you drop into an everyday reminder.
また、あとで電話します。
また、あとで でんわします。
I'll call you later.
あとで on its own just means 'later.'
What goes in front of あとで
This is where learners slip, because あとで is fussy about the shape of what precedes it:
| Connects to | Pattern | Example |
|---|---|---|
| Verb (action) | past (た) form + あとで | 食べたあとで = after eating |
| Noun (event) | noun + の + あとで | 授業のあとで = after class |
| Alone | あとで | あとで = later |
A verb must be in its た-form before あとで — never the dictionary form or the て-form. Remember that this た does not push the sentence into the past; it only marks the "after" relationship. A noun attaches with の: 仕事のあとで ("after work").
It helps to see あとで beside its mirror image, 前に (まえに, "before"). The meaning flips, and so does the verb form: あとで takes the past (た) form, while 前に takes the dictionary (plain present) form.
- 寝る前に歯を磨く = brush teeth before sleeping (前に → dictionary form 寝る).
- 寝たあとで本を読む = read a book after sleeping (あとで → past form 寝た).
There is also 〜てから ("after… and then"), which uses the て-form and stresses that the first action must finish before the next begins. あとで simply places one action after another, while てから highlights the sequence more strongly. For now, just anchor the rule: あとで needs the た-form.
あとで in action
After an action, the verb takes its た-form:
ヤッタンはご飯を食べたあとで散歩します。
ヤッタンは ごはんを たべた あとで さんぽします。
Yattan goes for a walk after eating.
ヤッタンは宿題をしたあとでゲームをします。
ヤッタンは しゅくだいを した あとで ゲームを します。
Yattan plays games after doing his homework.
お風呂に入ったあとで、牛乳を飲みます。
おふろに はいった あとで、ぎゅうにゅうを のみます。
After taking a bath, I drink milk.
入った is the past (た) form of 入る.
After an event, the noun attaches with の:
モチは授業のあとで先生に質問しました。
モチは じゅぎょうの あとで せんせいに しつもんしました。
Mochi asked the teacher a question after class.
Noun + のあとで for an event like 授業 (class).
ヤッタンの弟は学校のあとで公園で遊びます。
ヤッタンの おとうとは がっこうの あとで こうえんで あそびます。
Yattan's little brother plays at the park after school.
食事のあとで、みんなでお茶を飲みました。
しょくじの あとで、みんなで おちゃを のみました。
After the meal, everyone drank tea together.
Watch-outs
- Using the dictionary form before あとで. It must be the past (た) form: 食べるあとで ✗ → 食べたあとで ✓.
- Dropping の after a noun. A noun connects with の: 授業あとで ✗ → 授業のあとで ✓.
- Mixing up 前に and あとで forms. 前に takes the dictionary form (寝る前に); あとで takes the た-form (寝たあとで).
- Thinking た means past tense here. 食べたあとで散歩します is about the present/future — the た-form only signals "after."
The short version
- あとで = after; the earlier action or event comes in front of it.
- Verb → past (た) form + あとで: 食べたあとで.
- Noun → の + あとで: 授業のあとで.
- あとで by itself = "later."
- Opposite is 前に (before), which uses the dictionary form.
Practice it

Frequently asked questions
Why is the verb in the past (た) form before あとで?
The た-form here marks the 'after' relationship, not past tense. 食べたあとで散歩します ('go for a walk after eating') can be about the future — only the dictionary form is wrong before あとで.
How do I use あとで with a noun?
Connect the noun with の: 授業のあとで ('after class'), 仕事のあとで ('after work'). Don't drop the の.
What's the difference between あとで and 前に?
あとで means 'after' and takes the past (た) form: 寝たあとで. 前に means 'before' and takes the dictionary form: 寝る前に. They are mirror images.
Can あとで be used alone?
Yes. By itself, あとで means 'later': あとで電話します ('I'll call later').
Where 〜あとで fits
Don't confuse it with
- 〜てから · N5 — 〜てから links two actions in order: do X first, then Y. Learn the て-form + から pattern, how it differs from 〜たあとで, and why it is not the から that means 'because'.
- The て-form · N5 — The て-form is the gateway to dozens of Japanese grammar patterns. Learn the conjugation rules for every verb group, the famous song trick, and see clear examples.
- 〜から · N5 — から has two everyday jobs: 'because' (giving a reason) and 'from' (a starting point in time or place). Learn how each works, how it differs from ので, with clear examples.
More N5 grammar to explore
Keep going with related patterns at the same level:
- 〜前に — 〜前に means 'before': dictionary-form verb + 前に (寝る前に), noun + の前に (食事の前に), and time + 前に (三年前に). Always use the dictionary form — even for past events.
- 〜けど / 〜けれど — けど, けれど, and けれども all mean 'but/although,' joining two clauses in increasing order of politeness (けど is most casual). Attach after a plain or polite clause-ending, same as が.
- 〜ので — 〜ので gives a reason in a soft, polite way ('because…'). Learn how it attaches, how it differs from から, and why it's the safer choice for explanations and excuses.
