How to say "simplicity" in Japanese

Choosing the right word
  • 質実しつじつCommon
    na-adjective, nounSimplicity as plainness and lack of ostentation, in lifestyle, dress, or character. It suggests sober, unadorned moderation rather than mere ease, and is the natural choice for describing a simple, frugal way of life.
  • 簡かん
    nounSimplicity in the sense of compactness or brevity — something free of excess or elaboration. Because the gloss pairs it with brevity, it suits contexts where simple means concise or stripped down rather than plain in manner.
  • nounA loanword glossing only 'simplicity'. Given its lower commonness, it is seldom the word you want in ordinary Japanese; it tends to appear where the English term itself is kept, as in technical or stylish borrowed usage.
  • 単純性たんじゅんせい
    nounSimplicity as a property of being uncomplicated — the sense used in technical, mathematical, or scientific discussion, where one speaks of the simplicity of a system, structure, or explanation. Not the word for plain living.
  • 朴直ぼくちょく
    na-adjective, nounSimplicity bound up with honesty and naivete: an artless, unrefined but sincere character. It describes people or their manner rather than designs or systems, and its naivete nuance makes it a poor fit for neutral 'simplicity'.

Choose 質実 for plain, unadorned simplicity of living or style; 簡 for brevity-tinged simplicity; 単純性 for technical or logical simplicity; 朴直 for naive honesty; 「シンプリシティー」 is a rare loanword gloss.
