はともかく

はともかく is used when you want to acknowledge something as true or less important, but you want to shift focus to something more relevant or important in the current context. It signals that the speaker is setting aside the mentioned matter and not letting it affect the main point. It can soften criticism or reframe a situation. Note that it is more commonly used in casual to neutral formal speech; in very formal writing you might replace it with 脇に置く or さて, depending on context. The phrase typically appears before the main point you want to discuss, connected with the rest of the sentence as the thing you’re prioritizing or evaluating.
