How to say "organizer" in Japanese

• 幹事かんじCommon
  noun, suru verb, intransitive verbCovers 'organizer' in the sense of the person in charge of making arrangements for a gathering — the one who coordinates attendees and handles the details. Typical contexts include parties, reunions, and other group events.
  私、幹事かんじをやるのが初はじめてだから要領ようりょうが悪わるいかもしれません。↗

  This is the first time I've worked as a coordinator, so I may not have the hang of it yet.
• オルグCommon
  nounAn abbreviated loanword for 'organizer'. It is not the word for someone arranging a party or event; it suggests a person who rallies people for a movement, so it seldom fits an event's organizer.

For the organizer of a party, gathering, or event — the person who makes the arrangements — use 幹事; 「オルグ」 is an abbreviated loanword for someone who organizes people for a movement, and seldom fits that sense.
