〜じゃないか
〜じゃないか means isn't it; don't you think. It is a JLPT N4 grammar point. 「〜じゃないか」 is used to confirm something with the listener or to state a realization with some force. It is more conversational and casual than 「ではないか」. Depending on context, it can mean "isn't it?" or "see, it is...".
Japanese sources describe it as 「確認・驚き・強い気づき」.
