How to say "arbitration" in Japanese

Choosing the right word
  • 仲裁ちゅうさいCommon
    noun, suru verb, transitive verbThe core word for arbitration: a third party steps in to settle a dispute between two sides, whether a formal arbitral proceeding or an everyday act of intercession in a quarrel.
    彼かれが仲裁ちゅうさいしてその場ばは丸まるく収おさめた。↗
    He intervened and settled the matter peacefully for the time being.
  • 調停ちょうていJLPT N1approx.Common
    suru verb, transitive verb, no-adjectiveLeans toward the conciliation and mediation senses: a third party works to bring the disputing sides to a settlement they can both accept, rather than deciding the outcome for them.
    彼かれは両りょう当事者とうじしゃの間あいだを調停ちょうていした。↗
    He mediated between the two parties.
  • 裁定さいていCommon
    noun, suru verb, transitive verbPrimarily a decision or ruling handed down by an authority; seldom the word you want for arbitration as a process — it fits when the reference is to the award or final decision itself.

仲裁 centers on a third party stepping in to settle a dispute; 調停 stresses conciliation, helping the parties reach agreement; 裁定 names the ruling or award itself rather than the arbitration process.
