Choosing the right word
  • 予測よそくJLPT N3approx.Common
    noun, suru verb, transitive verbPrediction in the sense of estimating a concrete outcome or figure from available information; the analytical word for predicting results or numbers, as opposed to a subjective guess.
    何なんが起おこるか予測よそくできない。↗
    We cannot predict what will happen.
  • 予想よそうJLPT N1approx.Common
    suru verb, transitive verb, no-adjectiveThe general word for expecting or anticipating what will happen before it does: anticipating results, forming expectations, making a guess about an outcome. It covers both 'expectation' and 'prediction' and fits most ordinary contexts.
    あなたはどんな結果けっかを予想よそうしていますか。↗
    What results do you anticipate?
  • 予言よげんCommon
    noun, suru verb, transitive verbProphecy and foretelling: declaring what the future holds, often with a fateful or oracular nuance. For ordinary predictions of outcomes it is seldom the word you want.
    君きみの予言よげんが当あたったよ。↗
    Your prophecy has come true.
  • 予報よほうJLPT N3approx.Common
    noun, suru verb, transitive verbEssentially 'forecast': a prediction of conditions to come, above all the weather. For other senses of 'prediction' it is seldom the word you want.
    今夜こんやの予報よほうは雨あめである。↗
    Rain is forecast for this evening.
  • 思惑おもわくCommon
    nounReally 'expectation' or 'speculation': what someone privately anticipates or has in mind, often about markets or others' moves. As a rendering of 'prediction' it is marginal — reach for it only in that sense.

Use 予測 for an analytical estimate of an outcome or figure, 予想 for general expectations and guesses, 予言 for prophecy, 予報 for forecasts such as the weather, and 思惑 for a person's private expectation.
