How to say "soften" in Japanese

Choosing the right word
  • 溶けるとけるJLPT N2approx.Common
    ichidan verb, intransitive verbCovers the physical sense: something melts, thaws, or softens under heat, like ice thawing or butter softening. It is about a substance changing state, not about softening words or feelings.
    氷こおりが溶とけると液体えきたいになる。↗
    When ice melts, it becomes liquid.
  • 和らげるやわらげるJLPT N1approx.Common
    ichidan verb, transitive verbTransitive: you soften something — a tone, an attitude, an impact — or relieve pain. Use it when someone deliberately makes something harsh milder or gentler.
    その薬くすりは彼かれの苦痛くつうを和やわらげた。↗
    The medicine decreased his pain.
  • 和らぐやわらぐCommon
    godan verb, intransitive verbIntransitive counterpart of 和らげる: pain, tension, or a stern attitude softens, calms down, or eases. Use it when describing the softening itself rather than someone performing it.
    彼かれの優やさしい言葉ことばで彼女かのじょの気持きもちが和やわらいだ。↗
    She melted at his kind words.
  • 薄めるうすめるJLPT N2approx.Common
    ichidan verb, transitive verbSoftens in the abstract sense of toning down: a statement, an impression, or an effect is made weaker or less strong. It is about reducing intensity, not making anything physically soft.
  • 解きほぐすときほぐすCommon
    godan verb, transitive verbSoftens by loosening and untangling: relieving stress or tension, relaxing stiffness, or removing doubt. Natural in massage or relaxation contexts rather than for softening objects or words.

Use 「溶ける」 for physical melting or heat-softening, 「和らげる」 and 「和らぐ」 for softening tone, pain, or tension (transitive versus intransitive), 「薄める」 for toning down statements or impressions, and 「解きほぐす」 for loosening stress or dispelling doubt.
