If you study Japanese for even a short time, you will quickly encounter the words 前（まえ） and 後（あと）. At first, they may seem simple: 前まえ means “before” and 後あと means “after.” However, in real Japanese, these two words appear in many different contexts.

Sometimes they refer to time, sometimes to physical position, and sometimes they even mean “ago.” Because of this, learners often feel confused when they see them used in different ways.

Let’s break down the most common uses so you can understand how Japanese speakers actually use 前まえ and 後あと in everyday conversation.

---

1. 前 and 後 for Physical Position

One of the most basic meanings relates to space or position.

前（まえ） means in front, and 後ろ（うしろ） means behind.

Examples:

電車でんしゃの前まえに人ひとがいます。

(There is a person in front of the train.)

車くるまの後うしろに猫ねこがいます。

(There is a cat behind the car.)

👉 Notice that when talking about physical position, Japanese usually uses 後うしろ rather than just 後あと.

2. 前 and 後 for Time Order

Another very common use is talking about the order of events.

In this case:

前まえ = before
後あと = after

Examples:

ご飯はんの前まえに手てを洗あらってください。

(Please wash your hands before the meal.)

授業じゅぎょうの後あとで先生せんせいに質問しつもんしました。

(I asked the teacher a question after the class.)

日本にほんに来くる前まえに、日本語にほんごを少すこし勉強べんきょうしました。

(I studied a little Japanese before coming to Japan.)

ご飯はんを食たべた後あとでコーヒーを飲のみました。

(I drank coffee after eating.)

👉 When using nouns, attach の前まえ／の後あと.
👉 When using verbs, use dictionary form + 前まえ and た-form + 後あと.

3. 前 Meaning “Ago”

Here is where things become interesting. When 前まえ follows a time expression, it means “ago.”

Examples:

三年前さんねんまえに日本にほんに来きました。

(I came to Japan three years ago.)

五分前ごふんまえに電話でんわしました。

(I called five minutes ago.)

👉 This structure is very common when talking about past events.

---

4. 後 Meaning “Later”

When 後ご follows a time expression, it means “later” or “after.”

Examples:

三年後さんねんごに大学だいがくを卒業そつぎょうします。

(I will graduate from university in three years.)

五分後ごふんごに電車でんしゃが来きます。

(The train will arrive in five minutes.)

So remember:

前まえ = ago
後ご/あと = later

---

5. 前 Can Also Mean “Previous”

Another meaning of 前まえ is previous or last.

Examples:

前まえの会社かいしゃ

(my previous company)

前まえのレッスン

(the previous lesson)

👉 This meaning is also very common in everyday conversation.

Quick Summary

前 and 後 may look simple, but they cover several important meanings.

前（まえ）

• in front
• before
• ago
• previous

後（あと・ご）

• after
• later

Final Tip for Learners

A useful way to remember this is to think about direction in time.

• 前 points backward in time → ago
• 後 points forward in time → later

Once you start noticing these patterns, 前 and 後 will feel much more natural in Japanese conversations!
