Gesture & etiquette
Bow immediately upon approach, maintaining composure. Guide the visitor to a waiting area. Prepare tea or water as a courtesy. Return promptly and keep the visitor updated on the wait time.
In Japanese business culture, unannounced visits are unusual — they signal urgency. The phrase begins with appreciation rather than surprise, and immediately offers action ('I'll call them right away'). Offer the visitor a seat and water or tea while they wait.
