How to directly address a deputy director in conversation, using their title or name with honorifics.
In Japanese, you often address someone by their title plus さん, or simply by their last name + さん if the context is clear. Using the title directly (e.g., 副所長) can sound too formal or impersonal in direct address.
副所長さん、お電話です。
Deputy Director, you have a phone call.
田中副部長、ちょっとよろしいですか。
Deputy Director Tanaka, do you have a moment?
If the person's role is already known, simply using their last name with さん is natural and polite.
山田さん、会議の準備はできましたか。
Mr. Yamada, are the preparations for the meeting ready?
How to talk about a deputy director when they are not present, using appropriate honorific language.
When referring to someone by their title and name, use の to connect them. This is polite and clear.
副所長の山田さんがお見えになりました。
Deputy Director Yamada has arrived.
In more formal written contexts or when listing names, the title can follow the name directly without の.
山田副所長は本日不在です。
Deputy Director Yamada is absent today.
The English word 'deputy' does not have a single direct equivalent in Japanese. The prefix 副 (fuku) is used, but the second part of the title depends on the specific organization or role. Using 副 alone is incorrect.
Always check the specific Japanese title for the organization. For example, a deputy director in a company department is 副部長, while in a research institute it is 副所長. When in doubt, ask or use a more general term like 次長 (assistant director) if appropriate.
