How to tell them apart
において is a formal written-style compound particle used for the setting of an event, state, or time, while で is the everyday particle for the location where an action happens. Swapping them is unnatural because において sounds stiff in casual speech and で feels too plain in academic or official contexts. The core test is register: 会議において (formal) vs 会議で (casual/general).
- において/おける Use において/おける when you need a formal, written-style expression for the place or time of an event or state.
- で Use で for everyday statements about where an action takes place or a general contextual setting.

において/おける nioite okeru
In / at / on / during
において marks the place, field, or situation in which something happens or holds true, similar to で or に but more formal and written. It attaches to nouns, and おける is its attributive form used before a noun, as in 子育てにおいて. It often appears in set phrases like 何事においても, meaning in everything.
-
彼女の夫は何事においても自分の好きなようにしたがる。
Her husband wants to have his own way in everything.
-
彼は何事においても自分の思いどおりにしようとする。
He will have his own way in everything.
で de
Marks the location of an action, or the means or method used
The particle で follows a noun to mark the place where an action happens, or the means, tool, or method used to do it, as in イタリア語で (in Italian). It can also mark a role or capacity, like a bit part. It attaches directly after nouns.
-
ほんのちょいやくで人気があるのはすごい！
It's impressive that he's popular with just a bit part!
-
また後でかけ直していただけませんか？
