How to say "backing" in Japanese

Choosing the right word
  • 支援しえんCommon
    noun, suru verb, transitive verbThe general-purpose word for backing in the sense of aid or assistance — giving practical help, money, or resources to a person, group, or cause. It describes hands-on support rather than endorsement.
    私わたしたちは支援しえんを訴うったえた。↗
    We made an appeal for support.
  • 支持しじJLPT N1approx.Common
    noun, suru verb, transitive verbBacking in the sense of approval or endorsement: standing behind a person, policy, or organization rather than giving material aid. Choose this for political or public backing.
    我々われわれはこぞって君きみを支持しじする。↗
    We are solidly behind you.
  • noun, suru verb, transitive verbA loanword for backing an initiative, candidate, or the like — standing behind it and lending support when needed. It suggests active commitment rather than mere approval.
  • 後押しあとおしCommon
    noun, suru verb, transitive verbLiterally a push from behind: backing that boosts a person or project along, such as a parent backing a child's plans. It can also refer to the backer.
    もし彼かれの後押あとおしがあったならば、彼女かのじょは市長しちょうに選えらばれていただろう。↗
    With his support, she might have been elected mayor.
  • 援護えんごCommon
    noun, suru verb, transitive verbBacking in the sense of covering or shielding someone while they act — protective support rather than endorsement or aid. For backing a candidate or plan, this is seldom the word you want.
    彼かれを援護えんごするのが義務ぎむだ。↗
    It is incumbent on us to support him.

Choose 支持 for backing as endorsement or approval, 「バックアップ」 for backing an initiative or candidate, 「後押し」 for a boosting, encouraging kind of backing, 支援 for backing as aid, and 援護 for protective backing.
