Meaning

An adverb indicating the speaker's emotive feeling about an extreme state or situation. It means 'after all,' 'at any rate,' or 'the fact is' and provides a compelling reason for the preceding or following statement.

何しろ is used to introduce a reason or circumstance that the speaker considers overwhelming, undeniable, or extreme enough to justify a conclusion. It often conveys a sense of 'you have to understand that...' or 'the thing is...' The speaker uses 何しろ to emphasise that the reason being given is so strong that the outcome is inevitable or fully understandable. It can appear before or after the main clause. Compared to なにせ (a close synonym), 何しろ is slightly more conversational and emotive. It differs from なぜなら, which is a neutral 'because,' in that 何しろ carries emotional weight and a sense of extremity.

Examples

1. 何しろ初めての経験だから、緊張するのは当然だ。 After all, it's my first experience, so it's natural to be nervous.
2. 何しろ人口が多い国だから、どこへ行っても混んでいる。 The fact is, it's a country with a huge population, so it's crowded everywhere you go.
3. 準備が大変だった。何しろ参加者が五百人もいたからだ。 The preparations were tough. After all, there were five hundred participants.
