Mae ni, Ato de and Te kara: Before and After in Japanese

Describing what happens before or after something else is one of the first things you need for telling a story, explaining a routine or giving instructions. Japanese uses mae ni for before, ato de for after, and te kara for first this, then that. The rule learners most often break is the tense of the verb in front: mae ni always takes the dictionary form, even about the past, and ato de always takes the past form, even about the future. This guide covers those rules, nouns and time words, te kara for since, and how to choose between ato de and te kara.

Mae ni always follows the dictionary form, whatever the tense of the sentence

Ato de always follows the ta form, even when talking about the future

Te kara stresses order: do this first, then that

Te kara also means since, as in since I came to Japan

Three patterns for putting events in order

Each pattern links two actions and fixes the form of the verb that comes before it. Get the form right and the rest of the sentence behaves normally: the final verb carries the tense and politeness of the whole sentence.

JapaneseRomajiMeaning
寝る前に歯を磨きます。Neru mae ni ha o migakimasu.I brush my teeth before I go to bed.
食べた後で、散歩します。Tabeta ato de, sanpo shimasu.I go for a walk after I eat.
手を洗ってから、食べます。Te o aratte kara, tabemasu.I wash my hands and then eat.

Mae ni stays in the dictionary form

The verb before mae ni is always the non-past dictionary form, because at the time described the action had not yet happened. The tense of the whole sentence comes from the final verb.

This is where learners translate from English and produce tabeta mae ni. The fix is to remember that mae ni never looks backwards.

JapaneseRomajiMeaning
日本に来る前に、ひらがなを勉強しました。Nihon ni kuru mae ni, hiragana o benkyō shimashita.I studied hiragana before I came to Japan.
出かける前に、電話してください。Dekakeru mae ni, denwa shite kudasai.Please call me before you go out.
会議が始まる前に、資料を読んでおきます。Kaigi ga hajimaru mae ni, shiryō o yonde okimasu.I will read the documents before the meeting starts.
忘れる前に、メモします。Wasureru mae ni, memo shimasu.I will make a note before I forget.

Ato de stays in the past form

The mirror rule applies to ato de. The verb before it is always the ta form, because the first action is complete by the time the second one happens. That stays true even when the whole sentence is about the future.

JapaneseRomajiMeaning
仕事が終わった後で、ジムに行きます。Shigoto ga owatta ato de, jimu ni ikimasu.I will go to the gym after work finishes.
映画を見た後で、ご飯を食べました。Eiga o mita ato de, gohan o tabemashita.We had dinner after watching the film.
説明を聞いた後で、質問してください。Setsumei o kiita ato de, shitsumon shite kudasai.Please ask questions after you have heard the explanation.

Nouns, time words and ago

With nouns, both patterns take no: shokuji no mae ni, before the meal, and jugyō no ato de, after class. This is often the simplest way to say it in conversation, because you do not need a verb at all.

With a length of time, mae means ago and ato or go means later. Mikka mae is three days ago; sannen mae ni is three years ago.

JapaneseRomajiMeaning
食事の前に、薬を飲んでください。Shokuji no mae ni, kusuri o nonde kudasai.Please take the medicine before meals.
授業の後で、先生に質問しました。Jugyō no ato de, sensei ni shitsumon shimashita.I asked the teacher a question after class.
三年前に日本に来ました。Sannen mae ni Nihon ni kimashita.I came to Japan three years ago.
一時間後にまた来ます。Ichijikan go ni mata kimasu.I will come back in an hour.

Te kara: first this, then that

Te kara joins two actions and stresses that the first must be finished before the second begins. It often carries a sense of the right order or a condition: do this first, and only then do that.

It is the natural pattern for instructions, recipes, advice and household rules.

JapaneseRomajiMeaning
靴を脱いでから、上がってください。Kutsu o nuide kara, agatte kudasai.Please take off your shoes before coming in.
よく考えてから、答えます。Yoku kangaete kara, kotaemasu.I will think carefully before answering.
宿題をしてから、遊びなさい。Shukudai o shite kara, asobinasai.Do your homework first, then play.
確認してから、お返事します。Kakunin shite kara, ohenji shimasu.I will reply once I have checked.

In the first example, English naturally says before. Japanese often phrases the same instruction with te kara, stating the first action as complete.

Te kara for since

Te kara has a second use that ato de cannot replace: since, measuring time from a starting point. The pattern usually ends with a length of time or a change that has happened since then.

This is the phrase you need when people ask how long you have been in Japan or studying Japanese.

JapaneseRomajiMeaning
日本に来てから、三年になります。Nihon ni kite kara, sannen ni narimasu.It has been three years since I came to Japan.
日本語を勉強し始めてから、一年です。Nihongo o benkyō shihajimete kara, ichinen desu.It has been a year since I started studying Japanese.
引っ越してから、よく眠れるようになりました。Hikkoshite kara, yoku nemureru yō ni narimashita.I have been sleeping well since I moved.

Choosing between ato de and te kara

In many sentences both are correct and the difference is emphasis. Ato de answers when: the second action happens after the first. Te kara answers in what order: the first must be finished before the second.

When there is a gap in time or the two actions are loosely connected, ato de is more natural. When the order matters, or the first action is a condition, te kara fits better. For since, only te kara works.

JapaneseRomajiMeaning
じゃあ、後で電話します。Jā, ato de denwa shimasu.Okay, I will call you later.
昼ご飯を食べてから、出かけましょう。Hirugohan o tabete kara, dekakemashō.Let us head out once we have had lunch.
  • Loose sequence with time in between: ato de.
  • Deliberate order or a condition: te kara.
  • Instructions and advice: usually te kara.
  • Since a point in time: te kara only.
  • Later, with no first action named: ato de on its own.
Key points

A practical way to improve

Describe your evening routine in five sentences, using mae ni twice, ato de twice and te kara once. Then retell yesterday in the past tense and check that the verb before mae ni did not change. Telling your AI Sensei about your daily routine in Unihongo's 3D classroom is a good test, because sequence words appear in almost every sentence of that conversation.

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

Why is it taberu mae ni even when I am talking about the past?

Because at the moment before eating, the eating had not happened yet. Japanese sets the tense of the clause relative to the main event, not to now. Nemashita, taberu mae ni is correct; tabeta mae ni is a common learner error.

Can I say taberu ato de?

No. After describes something that has already happened relative to the next action, so it always takes the ta form: tabeta ato de. This is true even for future plans, as in tabeta ato de, eiga o mimasu.

What is the difference between ato de and te kara?

Ato de places the second action at some point after the first. Te kara stresses that the first action must be completed before the second starts, often as a condition or a deliberate order. Te kara also means since, which ato de cannot.

Is ato de the same as ato ni?

They are close. Ato de focuses on when the second action happens and is the common spoken choice for a single action. Ato ni can emphasise the order of things and appears more in writing. For everyday conversation, ato de is the safe choice.
