Learning how to express agreement is essential when engaging in conversations, both formal and informal, in any language. In Japanese, conveying your agreement gives a sense of understanding and respect to the person you are speaking with. Whether you’re discussing topics among friends, colleagues, or acquaintances, this guide will provide you with various ways to express agreement in Japanese, covering both formal and informal contexts. So let’s dive right in!

1. Formal Ways to Say “I Agree with You” in Japanese

When expressing agreement in formal situations, it’s crucial to use polite language to show respect. Here are some phrases you can employ:

1.1 The Basic Phrase:

One common way to agree formally in Japanese is using the phrase “そうですね” (sou desu ne). This simple expression conveys agreement and understanding. “Sou” means “that’s right” or “so,” while “ne” is a particle that emphasizes agreement.


Person A: 今日は本当に暑いですね。(Kyou wa hontou ni atsui desu ne.)
Person B: そうですね。(Sou desu ne.)
Person A: It’s really hot today, isn’t it?
Person B: That’s right.

1.2 Emphasizing Agreement:

If you want to show a stronger level of agreement or emphasize your understanding, you can use the following phrases:

  • “まったくです” (mattaku desu): This phrase means “exactly” or “that’s absolutely right” and conveys a strong agreement with the person’s statement.
  • “賛成です” (sanshoudesu): In this phrase, “賛成” (sanshou) means “agree” or “approval,” while “です” (desu) is a polite copula. Using this expression shows your formal agreement.
  • “その通りです” (sono toori desu): This phrase translates to “that’s correct” or “just as you said.” It implies complete agreement and understanding.


Person A: 私たちは早めにプロジェクトを終わらせるべきです。(Watashitachi wa hayame ni purojekuto o owaraseru beki desu.)
Person B: 賛成です。このまま頑張りましょう。(Sanshoudesu. Kono mama ganbarimashou.)
Person A: We should finish the project early.
Person B: I agree. Let’s continue working hard like this.

2. Informal Ways to Say “I Agree with You” in Japanese

In casual conversations, among friends or in laid-back settings, it’s suitable to use less formal expressions to convey agreement. Here are some phrases you can use:

2.1 The Basic Phrase:

To express agreement informally, you can use the phrase “そうだね” (sou da ne). This phrase is similar to the formal counterpart but uses the casual copula “だ” (da) instead of “です” (desu).


Person A: 今日の映画、面白かったね。(Kyou no eiga, omoshirokatta ne.)
Person B: そうだね。(Sou da ne.)
Person A: Today’s movie was interesting, right?
Person B: Yeah, that’s right.

2.2 Light Agreement:

When you want to express agreement in a more casual and playful manner, you can incorporate the following expressions into your conversations:

  • “まじで” (maji de): Meaning “seriously” or “for real,” this casual phrase demonstrates agreement in a more enthusiastic tone.
  • “その通りだよ” (sono toori da yo): This informal phrase is the casual version of the formal expression mentioned earlier. It means “that’s right” or “just as you said.”
  • “そう思うよ” (sou omou yo): Translated as “I think so” or “I feel the same way,” this phrase expresses agreement in a relaxed manner.


Person A: このレストランの料理、美味しいよね。(Kono resutoran no ryouri, oishii yo ne.)
Person B: まじで!また来たいな。(Maji de! Mata kitai na.)
Person A: The food at this restaurant is delicious, isn’t it?
Person B: Seriously! I want to come again.
