But; However (Formal Contrast Conjunction)
JLPT N5ConjunctionFormal
だが is a formal conjunction used at the beginning of a sentence to introduce a statement that contrasts with or opposes what was said in the previous sentence. It functions similarly to "but" or "however" in English. だが is composed of the plain copula だ plus the adversative particle が, giving it an inherently assertive and direct tone. Because of this, だが is most commonly found in written language such as essays, newspaper articles, novels, and formal speeches, and it is rarely used in casual everyday conversation. In comparison, でも and だけど serve similar contrastive functions but belong to casual spoken registers, while しかし is another formal written alternative that is slightly more neutral and versatile than だが. けれども sits between formal and neutral registers. Learners should note that だが always appears at the start of a new sentence (or clause), connecting two separate statements, rather than being embedded mid-sentence like が alone can be.
Functions
#1 Simple contrast between two facts
Structure
Statement A。だが、Statement B。
この店は安い。だが、味はとてもいい。
Here だが introduces a fact that contrasts with or is unexpected given the first statement. The speaker states the restaurant is cheap, which might suggest low quality, but then uses だが to pivot and reveal that the food actually tastes very good. This straightforward contrastive use is the most common function of だが, connecting two sentences where the second one presents surprising or opposing information.This restaurant is cheap. However, the taste is very good.

Common mistakes
A common mistake is using だが in casual conversation, where it sounds stiff and unnatural — learners should use でも or だけど instead when speaking informally. Another frequent error is placing だが in the middle of a sentence to connect two clauses, such as saying 「安いだが、おいしい」; this is incorrect because だが is a sentence-initial conjunction and should begin a new sentence or follow a clear pause, whereas the particle が alone can connect clauses mid-sentence (「安いが、おいしい」). Learners also sometimes confuse だが with ところが, but ところが specifically emphasizes a completely unexpected turn of events, while だが covers general contrast more broadly. Finally, attaching だが after い-adjectives or verbs directly (e.g., 「高いだが」) is a mistake because だ does not follow these forms — in such cases, simply starting the new sentence with だが after a period is the correct approach.
