一点確認させていただいてもよろしいでしょうか。 — Would it be alright if I clarified one point? (Workplace · Meeting, Formal to Superior, JLPT N2)

Gesture & etiquette

Raise your hand slightly or make brief, respectful eye contact with the presenter to signal you wish to speak. Keep an open, non-challenging posture — lean slightly forward, avoid crossing arms.

This softened question form is the correct way to raise a query or mild concern in a Japanese business meeting. Never bluntly say 'That's wrong' — frame disagreements as requests for clarification to preserve face (mentsu) for all parties.
