こそ「～が・けれど」 means but; although (emphasis). It is a JLPT N1 Japanese grammar pattern used to acknowledge a fact strongly before introducing a contrasting outcome or judgment.
This pattern appears in formal speech, essays, and JLPT N1 reading questions. When you want to concede a point in a way that feels deliberate and emphatic, こそ～が/けれど gives your Japanese a mature, precise edge.
What does こそ「～が・けれど」 mean?
Use こそ「～が・けれど」 when you want to emphasize that a certain condition or fact is true, but the result or next statement does not follow naturally from it.
Natural translations include:
- but; although (emphasis); it is true that … however
The structure puts weight on the first clause. The speaker is saying, “I’m not denying this — but even so, the other thing is the case.” It’s a concession wrapped in emphasis.
How to form こそ「～が・けれど」
The pattern follows this general attachment rule:
The verb is often する (in forms like した, すれ, する), ある, or whichever verb fits the situation. The noun before こそ is the thing being acknowledged.
Some common patterns:
努力こそしたが、結果は出なかった。感謝こそすれ、怒ってはいない。問題こそあるが、解決できる範囲だ。
For i‑adjectives, you cannot attach こそ directly to the adjective itself. Instead, use a construction like ～ことこそ or ～さこそ before the verb:
難しいことこそあるが、不可能ではない。嬉しさこそ感じたが、涙は出なかった。
When is こそ「～が・けれど」 used?
Use こそ～が/けれど in situations like:
- conceding a strong point before a counter‑argument
- expressing a realistic evaluation despite a clear merit or demerit
- softening a complaint by first acknowledging the positive
Tone and register:
- Formal to semi‑formal; often appears in writing, debates, and formal explanations.
- The けれど version leans slightly more conversational than が.
こそ「～が・けれど」 example sentences
After reading each sentence, ask what job こそ～が/けれど is doing: it takes a point you can’t deny and sets up a contrast. That makes its role clearer than any single English word.
Nuance of こそ「～が・けれど」
The key nuance is deliberate concession. The speaker stops to affirm something fully before moving on. This isn’t a simple “but” — it’s an intentional nod. The effect can be persuasive in argument, or soften a complaint by showing you’ve considered the other side.
For example, 努力こそしたが implies “Yes, I truly did make an effort — and yet…” That emotional weight is absent in a plain 努力したが, which would be neutral.
こそ「～が・けれど」 vs こそあれ
Both patterns use こそ to emphasise a concession, but they differ in scope and feel.
こそ～が/けれど:
- Works with any appropriate verb (する, ある, わかる, etc.)
- Slightly less literary, fits both spoken and written Japanese.
- Example:
お金こそあるが、自由な時間がない。
こそあれ:
- A fixed classical pattern using the 已然形 of ある → あれ.
- Implies “there is/are indeed … but”. Highly formal, often in written or formulaic speech.
- Example:
困難こそあれ、諦めるわけにはいかない。
Quick contrast:
問題こそあるが、大丈夫だ。問題こそあれ、進むしかない。If you’re in a casual conversation, こそあるが is more natural. If you want a dignified, slightly stiff tone, こそあれ fits. (See こそあれ for more.)
Common mistakes with こそ「～が・けれど」
A great way to internalise the pattern is to write a sentence with こそ～が, then rewrite it without こそ (only は or が). Observe how the emphasis disappears and the concession feels weaker.

That means learners should be able to:
- recognise it in advanced reading passages
