How to say "inspector" in Japanese

Choosing the right word
  • 監察官かんさつかんCommon
    nounAn official whose post is to inspect and supervise, often checking that organizations or staff are acting properly; use it when 'inspector' means the person holding such a post, not the act itself.
  • 監察かんさつCommon
    noun, suru verb, transitive verbChiefly the act of inspection and supervision; its 'inspector' sense points to the office or post rather than to a person, so for an individual inspector 監察官 is the word you want.
  • 監査役かんさやくCommon
    nounThe company officer who audits the directors' execution of their duties — the corporate statutory auditor; 'inspector' here only in this corporate-audit sense, never a general inspector.
  • 監事かんじCommon
    nounA title for the officer in charge of supervising and auditing an organization's affairs, used as a post name in associations and similar bodies; not a general word for an inspector.

Use 監察官 for an official who inspects and supervises, 監察 for the inspection or the post itself, 監査役 for a company's auditing officer, and 監事 for a supervising officer of an association.
