In Japan, it is common to add 'san' after someone's name.

Gesture & etiquette
When being introduced, listen carefully to how Japanese speakers address each other — the honorifics used reveal relationships and social hierarchy instantly. When unsure, always default to 'san' — it is safe across all contexts except intimate friendship.
Always use 'san' when addressing someone until they explicitly invite you to use their given name or a more casual form. Using given names without permission, or omitting 'san,' signals presumptuous familiarity. 'Sama' (more formal), 'kun' (boys/junior males), and 'chan' (children/close friends) have distinct appropriate uses.
