  nounA person who runs an operation or group of workers and answers for it — the 'controller' sense here is a boss or overseer, not a device or a financial officer.
• 監事かんじCommon
  nounAn officer of an organization charged with auditing its accounts; it matches the financial 'controller, comptroller' sense and is the title of a post, not a general word for controlling.
