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, time, or field in which something happens or holds true, similar to in, at, or on. It attaches to a noun, as in 日本において, and における is the form used when the phrase modifies another noun, as in 日本における研究. It is formal and common in writing, news, and academic contexts, where で or に would sound too casual.

で de
Marks the location of an action, or the means or method used
で follows a noun to show where an action takes place, as in ボストンで買った, or what means is used to do something, as in バスで学校に行きます. It attaches directly to the noun without any change to the noun itself. Be careful not to confuse it with に, which marks the place where something exists or the destination of movement rather than the place of an action.
