Gesture & etiquette
A relaxed, warm smile is appropriate for this casual colleague invitation. Keep the tone light and low-pressure — this is workplace rapport-building, not a formal request. If the invitation is declined, accept it graciously without pressing further.
Workplace lunch culture varies by office — some teams have a strong 弁当 (bento lunchbox) culture where colleagues eat at their desks, while others regularly go out. Reading the culture before inviting is important. If the person hesitates, add 「お時間があれば」to give them a polite out.
