に vs で: Choosing the Right Particle for Places and Actions

Early on, many learners treat に and で as two spellings of the same English word, "at" or "in." Then a test question asks them to fill in a blank, and both options look fine. They are not interchangeable, and there is a reliable way to choose.

The one-line test

Ask what the verb is doing.

If the verb describes existence or arrival at a place (being, going, putting, arriving), the place takes に.
If the verb describes an action happening in a place (eating, studying, buying, playing), the place takes で.

Compare:

私は東京に住んでいます。— I live in Tokyo. (state of being there)
私は東京で働いています。— I work in Tokyo. (an action done there)

に: where something exists or is headed

Existence: ある, いる

机の上に本があります。— There is a book on the desk.
公園に子供がいます。— There are children in the park.

Destination: 行く, 来る, 帰る, 入る

学校に行きます。— I go to school.
部屋に入ってください。— Please enter the room.

For destinations, へ is also possible: 学校へ行きます. The difference is small at this level.

Point of arrival or placement: 着く, 座る, 置く

駅に着きました。— I arrived at the station.
椅子に座ります。— I sit on the chair.
かばんを机の上に置いた。— I put my bag on the desk.

Time

に also marks specific points in time: 七時に起きます, 日曜日に会いましょう.

で: where an action takes place

図書館で勉強します。— I study at the library.
レストランで昼ご飯を食べました。— I ate lunch at a restaurant.
駅で友達に会いました。— I met a friend at the station.

Notice that 会う (to meet) takes で for the place, because meeting is an event that happens somewhere. The person you meet takes に.

で has a second job: means and tools

で also marks the tool, method, or material.

バスで行きます。— I go by bus.
日本語で話してください。— Please speak in Japanese.
ペンで書きます。— I write with a pen.

If the noun before で is not a place, it is almost always a means. This second job explains why で shows up so often.

The tricky cases

Verbs that look like actions but take に

住む (to live) takes に for the place, because it describes where you exist.
泊まる (to stay overnight): ホテルに泊まる.
勤める (to be employed at): 銀行に勤めている.

Verbs that take で even though you are "at" the place

勉強する, 働く, 遊ぶ, 食べる, 買う all take で. They are all actions.

住んでいる vs 働いている

A good memory pair: live = に, work = で. Say it as a chant until it is automatic.

Quick practice

Fill in に or で:

毎朝、公園（　）散歩します。
猫がソファ（　）います。
友達の家（　）泊まりました。
電車（　）会社へ行きます。
図書館（　）本を借りました。

Answers: 1 で, 2 に, 3 に, 4 で (means), 5 で.

How the JLPT tests this

Particle questions are common at N5 and N4. They usually give a short sentence with a blank and four particle options. The trick is to look at the verb first, not the noun. If you are unsure, ask the test above: existence or arrival (に), or an action in a place (で), or a tool/method (で).

When you miss one, put it in a mistake log with the verb and the reason. The verb is the clue you overlooked, and writing it down helps you spot it next time.

Practice with explanations

JLPT Ready's Dojo Practice mode removes time pressure and explains every answer, which is ideal for particle drills where the reason matters more than the answer. You can start free with N5, no card required.
