Sequencing: 前に vs あとで vs てから – Japanese Cheat Sheet

Japanese has three main ways to express "before" and "after": 前に (mae ni), あとで (ato de), and てから (te kara). They look interchangeable at first, but each has different tense rules and slightly different implications. Getting them wrong sounds unnatural even if you're understood.

Expression	Meaning	Verb form before it	Emphasis
〜前に	before 〜	Dictionary form (always)	Something happens before an event
〜あとで	after 〜	た-form (past plain)	Sequence first this, then that
〜てから	after doing 〜 (then)	て-form	Strong sequential order the second thing follows directly

1. 〜前に "before doing 〜"

Means "before [action]". The verb before 前に is always in dictionary form, even when the main sentence is in the past. This trips up learners don't make it past tense.

寝ねる前に、歯はを磨みがきます。I brush my teeth before going to bed.

食たべる前に、手てを洗あらってください。Please wash your hands before eating.

日本にほんに来くる前に、少すこし勉強べんきょうしました。I studied a little before coming to Japan. (verb stays dictionary form even though sentence is past)

出発しゅっぱつする前に、もう一度いちど確認かくにんしよう。Let's check one more time before departing.

Key rule: The verb before 前に is always dictionary form 食べた前に is wrong. It must be 食べる前に, even when talking about the past.

2. 〜あとで "after 〜" (loose sequence)

Means "after doing 〜". The verb before あとで is in た-form (past plain). The sequence is looser there can be a gap between the two actions. Also works with nouns directly: 食事の後で.

食たべたあとで、散歩さんぽしましょう。Let's take a walk after eating.

仕事しごとが終おわったあとで、電話でんわします。I'll call you after work finishes.

映画えいがを見みたあとで、感想かんそうを話はなしましょう。Let's talk about our impressions after watching the film.

会議かいぎのあとで、資料しりょうを送おくります。I'll send the materials after the meeting. (noun + のあとで)

3. 〜てから "after doing 〜, then immediately..."

Also means "after 〜, then 〜" but with a stronger sense of sequential order. The second action follows as a direct result or immediately after completing the first. You can't swap them. Uses the て-form.

手てを洗あらってから、食たべましょう。Let's eat after washing our hands. (must wash first, then eat)

大学だいがくを卒業そつぎょうしてから、就職しゅうしょくした。After graduating university, I got a job. (direct sequence)

考かんがえてから返事へんじしてください。Please think it over before replying. (literally: after thinking, reply)

日本にほんに来きてから、日本語にほんごが上手うまくなった。Since coming to Japan (after coming to Japan), my Japanese improved. (the two are directly linked)

あとで vs てから the real difference

Both mean "after" but てから implies the second action depends on or directly follows the first. あとで just says "later, after X."

あとで (loose sequence)

食たべたあとで、テレビを見みた。

After eating, I watched TV. (casual things happened in order, but no strong link)

てから (strong sequence)

宿題しゅくだいをしてから、テレビを見みなさい。

Watch TV after you do your homework. (the order is mandatory do homework first, then TV)

Memory trick: 前に = always dictionary form (not past). あとで = た-form (past plain) + loose "after". てから = て-form + strong sequential "then". If the order is mandatory or directly linked, use てから.
