How to say "indeed" in Japanese

Choosing the right word
  • なるほどJLPT N4approx.Common
    interjection, adverbCovers the 'indeed' of acknowledgment: replying to what someone has just told you with 'I see, so that's right.' It is a conversational response, not a word for strengthening your own statement.
    なるほど彼かれは若わかいが、用よう心深こころふかい。↗
    Indeed he is young, but he is prudent.
  • いかにもJLPT N1approx.Common
    adverbUsed to affirm emphatically that what another person says is true, with wholehearted agreement. Its 'just (like)' sense presents something as the very picture of a quality.
    こんな格好かっこうをしているといかにもスポーツしてそうに見みえるけど、全然ぜんぜんやってないんだよ。↗
    I look for all the world like an athlete in this outfit, but the truth is I don't do any sports at all.
  • 実にじつにJLPT N3approx.Common
    adverbThe adverbial 'indeed/really/truly' that strengthens a statement or quality — 'truly remarkable,' 'indeed moving.' It sits inside the sentence to intensify what you are saying, rather than serving as a reply.
    今日きょうは実じつによい天気てんきだ。↗
    It is truly a nice day today.
  • 千万せんばんCommon
    noun, suffix, adverbChiefly an intensifier meaning 'exceedingly' or 'extremely'; its 'indeed' sense is marginal, so this is seldom the word you want for 'indeed' — reach for it only when 'exceedingly' is what you mean.
  • まったくJLPT N3approx.Common
    adverb, no-adjectiveThe 'indeed' of emphatic agreement; it can stand alone as a reply — 'Quite so.' It also works as an intensifier meaning 'completely,' so it both agrees with a statement and underscores it.
    「彼女かのじょはきれいだね」「まったくだ」↗
    "She is lovely." "So she is."

Choose 「なるほど」 for the 'indeed' that acknowledges what you have just learned, 「いかにも」 or 「まったく」 for emphatic agreement, 「実に」 for the adverbial 'indeed/truly' that intensifies a statement, and treat 千万 as marginal for this meaning.
