に vs で: Which One?使い分け
に and で both mark locations, but they serve different functions. に marks where something EXISTS or the DESTINATION of movement. で marks where an ACTION takes place. This distinction is the #1 source of particle errors for Japanese learners.

The fundamental rule
Ask one question: Is it existence/destination, or is it an activity? If you can answer with "something is THERE" or "going THERE," use に. If you can answer with "doing something THERE," use で. 公園にいる (am in the park — existence). 公園で遊ぶ (play in the park — action). This single distinction covers 90% of cases.
Rule 1: に with existence verbs
いる, ある, 住む, 泊まる — these describe being/existing somewhere: 東京に住んでいる (live in Tokyo), ホテルに泊まる (stay at a hotel), 机の上に本がある (there's a book on the desk). All take に because the verb describes existing, not acting.
Rule 2: で with action verbs
食べる, 働く, 勉強する, 遊ぶ, 買う — these are actions performed at a location: カフェで勉強する (study at a cafe), 会社で働く (work at the company), スーパーで買い物する (shop at the supermarket). で provides the stage where the action unfolds.
Rule 3: に for destinations
Motion verbs (行く, 来る, 帰る, 着く) take に for the destination: 学校に行く (go to school), 家に帰る (go home). で does not mark destinations — it only marks where you perform an action after arriving.
Rule 4: Tricky verbs that change meaning
Some verbs can take either particle with different meanings. 椅子に座る (sit down ON the chair — destination of your body) vs カフェで座る (sit AT the cafe — the cafe is where the sitting activity occurs). 黒板に書く (write ON the blackboard — target surface) vs 教室で書く (write IN the classroom — location of writing activity).
The surface/target rule
When something contacts or attaches to a surface, use に: 壁に絵を掛ける (hang a picture on the wall), ノートに書く (write in a notebook). The surface is the target/destination, not the activity location.
Rule 5: で for events and gatherings
Events use で because they involve activities: パーティーで会った (met at a party), 会議で決まった (was decided at the meeting), 試合で勝った (won in the match). The event is the context for the action.
Rule 6: Edge cases and exceptions
働く always uses で (会社で働く), even though you could argue you "exist" at work. The action trumps existence. 入る takes に (部屋に入る) because it’s a destination verb. 並ぶ can take に (列に並ぶ = line up in a line — target) or で (店で並ぶ = line up at a store — location). Context determines which particle is correct.

Common mistakes
東京で住んでいます。
東京に住んでいます。
住む is an existence verb (you exist/reside somewhere). Use に, not で.
学校に勉強する。
学校で勉強する。
勉強する is an action. The place where you perform an action takes で. に would only work as a destination (学校に行く).
ベッドで寝ている (meaning "lying on the bed")
ベッドに寝ている (lying on the bed) / ベッドで寝ている (sleeping in the bedroom area)
Both can work but differ. に emphasizes the target surface (on the bed). で emphasizes the location of the activity. For "lying on the bed," に is more natural.
Frequently asked questions
Is there a single trick to always get に vs で right?
Yes: ask "Is the verb about BEING there or DOING there?" Being = に. Doing = で. For verbs like 住む (live), 泊まる (stay), いる/ある (exist), use に. For everything else (working, eating, playing, studying), use で.
What about 座る (sit)?
椅子に座る = sit ON the chair (に marks what you sit on — the target). 部屋で座る = sit in the room (で marks where the sitting happens). The target/surface gets に; the general area gets で.
Does 働く use に or で?
Always で: 会社で働く (work at the company). Even though you "exist" at work, 働く is an action verb. The action-context rule wins.
