How to say "equality" in Japanese

Choosing the right word
  • 平等びょうどうJLPT N3approx.Common
    na-adjective, no-adjectiveThe general word for equality as a principle: fair, impartial, even treatment of people. It fits talk of equality before the law or in society, stressing fairness rather than a comparison between two parties.
    すべての人間にんげんが平等びょうどうに創つくられているわけではない。↗
    Not all men are created equal.
  • 同等どうとうJLPT N1approx.Common
    na-adjective, no-adjectiveEquality as being on the same level as another: the same rights, rank, or conditions. Use it when stating that one person or thing is equal to another, as in equal treatment.
    1メートルは1ヤードとは完全かんぜんに同等どうとうではない。↗
    A meter is not quite equivalent to a yard.
  • 対等たいとうJLPT N1approx.Common
    no-adjective, na-adjectiveEquality of status between two parties: being on an equal footing or equal terms, with neither side superior. Typical of relationships, negotiations, or partnerships where both sides stand as equals.
    あなたは私と対等たいとうで私より下したでも上うえでもない。↗
    You are my equal; not my inferior or superior.
  • 均一きんいつCommon
    na-adjective, no-adjectiveReally uniformity rather than equality between people: things being made uniform or identical, as in uniform prices or quality. Seldom the word you want for equality in rights or status.
  • 同格どうかくJLPT N2approx.Common
    no-adjective, na-adjectiveEquality specifically in rank or grade: being of the same standing as something else. It fits statements that one thing ranks equal with another, and is narrower than the abstract idea of equality.

Choose 平等 for equality as a principle or impartial treatment; 同等 and 対等 for being equal with another party in rights, rank, or footing; 同格 for equal rank; 均一 is really uniformity, not equality between people.
