How to say "diplomat" in Japanese

• 外交官がいこうかんCommon
  nounThe usual word for a diplomat as a profession: someone who represents their country at an embassy or foreign ministry. For the occupation or official role, this is the word you want.
  その会議かいぎには１５０人にんの外交官がいこうかんがきた。↗

  The conference drew 150 diplomats.
• 外交使節がいこうしせつ
  nounAn envoy or official mission sent by a government for a specific diplomatic purpose; it denotes the envoy or delegation dispatched, not a career, so it is seldom the word for the profession.
• ディプロマット
  nounA katakana loanword for 'diplomat'; it is less common, and 外交官 remains the word you will normally want. Recognizable, but seldom the natural choice when you need the word in Japanese.
• 外交家がいこうか
  nounA person skilled in diplomacy, or figuratively someone diplomatic — tactful and adept at handling people. It centers on personal ability rather than official position, so it does not simply mean a professional diplomat.

Choose 外交官 for a diplomat as a profession or official role; 外交使節 for an envoy or mission dispatched on official business; 外交家 for a person skilled or tactful in diplomacy; 「ディプロマット」 is a less common loanword alternative.
