Translation guide
A pretext is a false reason given to hide the real reason for doing something. In Japanese, this is commonly expressed with nouns like 口実 (こうじつ) or 名目 (めいもく), or by using the pattern 〜を口実に (〜をこうじつに). The choice depends on formality and whether the focus is on the excuse itself or the action taken under that excuse.
Expressing that someone uses a stated reason as a cover for their real intention.

口実 (こうじつ) is a neutral term for a pretext or ostensible reason, often planned in advance. 言い訳 (いいわけ) is an excuse made after the fact to justify or defend oneself. Using 言い訳 when you mean a deliberate pretext can sound like you are making a weak excuse.
There is no single Japanese word that covers all uses of 'pretext'. Avoid direct translations like 前置き (which means 'preface' or 'introductory remarks'). Use 口実 or the patterns above depending on context.
