How to Say Before and After in Japanese with While and During

Talking about time in Japanese can feel very polite and organized… until you try to say “after lunch,” “before I go,” “while studying,” and “during the meeting” in one sentence. Suddenly your brain is wearing mismatched socks.

Good news: Japanese time words are wonderfully logical once you learn the patterns. The big stars today are 前 mae meaning “before,” 後 ato meaning “after,” 間 aida meaning “during/while,” and ながら nagara meaning “while doing.”

There are a few tiny grammar switches, because Japanese enjoys making learners earn their snacks. But once you know which form to use, these expressions become extremely useful for everyday Japanese.

The Big Four Time Words

Start with these core words. They do most of the heavy lifting when you want to talk about what happens before, after, while, or during something.

Yak wisdom: 前 mae looks backward in time, 後 ato looks forward after something, and 間 aida stands awkwardly in the middle holding a calendar.

How To Say Before In Japanese

To say “before,” use 前に mae ni. The particle に ni points to the time when something happens.

The form changes depending on whether the word before it is a noun or a verb. Tiny grammar goblin, manageable size.

Pattern	Rōmaji	Meaning	Example	Example Rōmaji	Translation
名詞の前に	meishi no mae ni	before a noun/event	授業の前にコーヒーを買います。	Jugyō no mae ni kōhī o kaimasu.	I buy coffee before class.
動詞辞書形前に	dōshi jisho-kei mae ni	before doing a verb	日本へ行く前に、少し日本語を勉強します。	Nihon e iku mae ni, sukoshi Nihongo o benkyō shimasu.	Before going to Japan, I study a little Japanese.
朝ご飯の前に	asagohan no mae ni	before breakfast	朝ご飯の前に散歩します。	Asagohan no mae ni sanpo shimasu.	I take a walk before breakfast.
寝る前に	neru mae ni	before sleeping	寝る前に本を読みます。	Neru mae ni hon o yomimasu.	I read a book before sleeping.

Notice this important bit: before a noun, Japanese uses の no: 仕事の前に shigoto no mae ni, “before work.” Before a verb, use the plain dictionary form: 食べる前に taberu mae ni, “before eating.”

How To Say After In Japanese

To say “after,” use 後で ato de. The particle で de often marks the point or setting where the next action happens.

With nouns, use の後で no ato de. With verbs, use the past plain form, also called the た形 ta-kei, before 後で ato de.

Pattern	Rōmaji	Meaning	Example	Example Rōmaji	Translation
名詞の後で	meishi no ato de	after a noun/event	学校の後でアルバイトに行きます。	Gakkō no ato de arubaito ni ikimasu.	I go to my part-time job after school.
動詞た形後で	dōshi ta-kei ato de	after doing a verb	晩ご飯を食べた後で、映画を見ました。	Bangohan o tabeta ato de, eiga o mimashita.	After eating dinner, I watched a movie.
仕事の後で	shigoto no ato de	after work	仕事の後でジムへ行きます。	Shigoto no ato de jimu e ikimasu.	I go to the gym after work.
シャワーを浴びた後で	shawā o abita ato de	after taking a shower	シャワーを浴びた後で、すぐ寝ました。	Shawā o abita ato de, sugu nemashita.	After taking a shower, I went to sleep right away.

One useful shortcut: 後で ato de by itself can mean “later.”

Key Phrase	Rōmaji	Meaning	Example	Example Rōmaji	Translation
後で	ato de	later	後で電話します。	Ato de denwa shimasu.	I will call later.
また後で	mata ato de	see you later; later again	また後で話しましょう。	Mata ato de hanashimashō.	Let’s talk again later.
少し後で	sukoshi ato de	a little later	少し後でメールを送ります。	Sukoshi ato de mēru o okurimasu.	I will send an email a little later.
その後で	sono ato de	after that	買い物をしました。その後で、家に帰りました。	Kaimono o shimashita. Sono ato de, ie ni kaerimashita.	I went shopping. After that, I went home.

Before And After Side By Side

Here is the clean comparison. If you remember only one thing, remember this: before a verb uses dictionary form, but after a verb uses past plain form.

English Idea	Japanese Pattern	Rōmaji	Example	Example Rōmaji	Translation

How To Say While And During In Japanese

English uses “while” and “during” in a few different ways. Japanese splits these ideas into several useful patterns: 間 aida, 間に aida ni, ながら nagara, 中 chū, and うちに uchi ni.

Yes, that looks like a lot. No, you do not need to panic dramatically near a houseplant.

Using 間 Aida For During A Whole Period

Use 間 aida when something continues during the same period. It often means “for the whole time” or “while.”

Key Phrase	Rōmaji	Meaning	Example	Example Rōmaji	Translation
休みの間	yasumi no aida	during the break	休みの間、ずっと家にいました。	Yasumi no aida, zutto ie ni imashita.	During the break, I stayed home the whole time.
授業の間	jugyō no aida	during class	授業の間、静かにしてください。	Jugyō no aida, shizuka ni shite kudasai.	Please be quiet during class.
旅行の間	ryokō no aida	during the trip	旅行の間、たくさん写真を撮りました。	Ryokō no aida, takusan shashin o torimashita.	During the trip, I took many photos.
待っている間	matte iru aida	while waiting	待っている間、本を読んでいました。	Matte iru aida, hon o yonde imashita.	While waiting, I was reading a book.

Using 間に Aida Ni For Something That Happens During A Window

Use 間に aida ni when an action happens at some point during a time window. It does not necessarily continue the whole time.

Key Phrase	Rōmaji	Meaning	Example	Example Rōmaji	Translation
留守の間に	rusu no aida ni	while someone is away	留守の間に荷物が届きました。	Rusu no aida ni nimotsu ga todokimashita.	A package arrived while I was away.
寝ている間に	nete iru aida ni	while sleeping	寝ている間に雨が降りました。	Nete iru aida ni ame ga furimashita.	It rained while I was sleeping.
若い間に	wakai aida ni	while young	若い間にいろいろな経験をしたいです。	Wakai aida ni iroiro na keiken o shitai desu.	I want to have many experiences while I am young.
日本にいる間に	Nihon ni iru aida ni	while in Japan	日本にいる間に京都へ行きたいです。	Nihon ni iru aida ni Kyōto e ikitai desu.	I want to go to Kyoto while I am in Japan.

The tiny difference is powerful: 間 aida often describes something continuing through the period. 間に aida ni often describes something happening within the period.

Using ながら Nagara For Two Actions At The Same Time

Use ながら nagara when the same person does two actions at the same time. Attach it to the verb stem, the part before ます masu.

Key Phrase	Rōmaji	Meaning	Example	Example Rōmaji	Translation
食べながら	tabe nagara	while eating	テレビを見ながらご飯を食べます。	Terebi o mi nagara gohan o tabemasu.	I eat while watching TV.
歩きながら	aruki nagara	while walking	歩きながら電話しないでください。	Aruki nagara denwa shinai de kudasai.	Please do not talk on the phone while walking.
聞きながら	kiki nagara	while listening	音楽を聞きながら料理します。	Ongaku o kiki nagara ryōri shimasu.	I cook while listening to music.
考えながら	kangae nagara	while thinking	考えながらゆっくり話しました。	Kangae nagara yukkuri hanashimashita.	I spoke slowly while thinking.

Important: ながら nagara usually needs the same subject. If one person is sleeping and another person is cleaning, use 間に aida ni, not ながら nagara.

Using 中 Chū For In The Middle Of Something

中 chū means “in the middle of” or “during.” It is common with events, activities, and status words. You will see it on signs too, which is handy and mildly bossy.

Key Phrase	Rōmaji	Meaning	Example	Example Rōmaji	Translation
会議中	kaigi chū	during a meeting; in a meeting	会議中なので、後で電話します。	Kaigi chū na node, ato de denwa shimasu.	I am in a meeting, so I will call later.
勉強中	benkyō chū	studying; in the middle of study	今、勉強中です。	Ima, benkyō chū desu.	I am studying now.
食事中	shokuji chū	during a meal	食事中に大きな声で話さないでください。	Shokuji chū ni ōkina koe de hanasanai de kudasai.	Please do not speak loudly during the meal.
工事中	kōji chū	under construction	この道は工事中です。	Kono michi wa kōji chū desu.	This road is under construction.

Mini Practice

Try choosing the best Japanese phrase. The answers are right below, so no dramatic scrolling required.

English Prompt	Best Japanese	Rōmaji	Translation
Before drinking coffee	コーヒーを飲む前に	Kōhī o nomu mae ni	Before drinking coffee
After drinking coffee	コーヒーを飲んだ後で	Kōhī o nonda ato de	After drinking coffee
While listening to music	音楽を聞きながら	Ongaku o kiki nagara	While listening to music
During the meeting	会議中	Kaigi chū	During the meeting
While I am in Japan	日本にいる間に	Nihon ni iru aida ni	While I am in Japan
Before the test	テストの前に	Tesuto no mae ni	Before the test

Now put them into full sentences. For example: コーヒーを飲む前に、水を飲みます。 Kōhī o nomu mae ni, mizu o nomimasu. “Before drinking coffee, I drink water.” Very responsible. Almost suspiciously responsible.

Yak Takeaway

For “before,” use 前に mae ni: 行く前に iku mae ni, “before going.” For “after,” use 後で ato de: 行った後で itta ato de, “after going.” For “while” and “during,” choose the flavor you need: 間 aida for a whole period, 間に aida ni for something inside a time window, ながら nagara for two actions at once, and 中 chū for being in the middle of something.

Japanese time expressions look fussy at first, but they are really just small building blocks. Stack them calmly, and suddenly you can explain your whole day in Japanese: before coffee, after work, during meetings, while pretending not to check your phone. Progress.
