How to say "councillor" in Japanese

• 参事官さんじかんCommon
  nounThe official title for a senior officer in a government ministry or a diplomatic mission; use it when 'councillor' names a specific administrative or embassy post rather than a member of a deliberative council.
• 参事さんじCommon
  nounOn its own this is seldom the word you want for 'councillor': its primary sense is secretary, and it mostly appears inside official titles such as 参事官.
• 評議員ひょうぎいんCommon
  nounA member of a council or board that deliberates on an organization's affairs; this is the natural choice when 'councillor' means someone who sits on such a body, and it also covers 'trustee'.
• 参与さんよCommon
  nounAn advisory post rather than a seat on a council: use it when 'councillor' is close to 'adviser' or 'consultant', someone who gives counsel to an office or organization.

Choose 参事官 for the official government or embassy post, 評議員 for a member of a council or board, 参与 for an advisory role, and treat 参事 as a marginal, mostly title-bound variant.
