How to Say I Agree in Japanese: Sō Desu Ne, Tashika Ni, Sansei Desu

Agreeing sounds simple until you notice how many kinds of agreement there are. You can agree with a feeling (that film was long), with a point someone makes (good point, that's true), with an opinion in a discussion (I have the same view), or with a proposal that a group will decide on (I'm in favour). Japanese has a different natural phrase for each, and using the wrong one can make you sound distant, overly formal or, surprisingly often, unsure. This guide climbs the ladder from casual sō da ne and da yo ne to the respectful ossharu tōri desu, shows how to agree with only part of what someone said, gives you the phrases that work in a meeting, and ends with a brief look at soft disagreement. You will also see why dōi shimasu, the dictionary translation of I agree, is rarely what you want.

Sō desu ne and watashi mo sō omoimasu are the safe everyday choices

Tashika ni agrees with a point; sansei desu supports a proposal

Partial agreement: sō iu kangaekata mo arimasu ne, then your view

Dōi shimasu means consent to terms, not agreement in conversation

I agree in Japanese: the four core phrases

Most agreement in Japanese happens with these four phrases. They go from the gentle everyday nod to a clear position in a decision.

From the everyday nod to a clear vote: four ways to agree in Japanese.
JapaneseRomajiMeaning
そうですね。Sō desu ne.That's right. (polite)
確かに。Tashika ni.True. / Good point.
私もそう思います。Watashi mo sō omoimasu.I think so too.
賛成です。Sansei desu.I'm in favour.

Sō desu ne agrees with a feeling or a comment, tashika ni with a point, watashi mo sō omoimasu with an opinion, and sansei desu with a proposal. Matching the phrase to what you are agreeing with is most of the skill.

Sō desu ne, sō da ne and da yo ne: everyday agreement

Sō desu ne is the first phrase most learners meet, and it really is everywhere. Said briskly with a short ne, it means that's right, I agree. Said slowly with a long, falling nē, it means well, let me think, and often comes before a polite no. Your tone decides which one you meant, so keep it short and bright when you agree.

With friends, the casual forms are sō da ne, sō sō, right, right, and da yo ne, right?, which agrees strongly, as if you had been thinking the same thing. Desu yo ne is the polite version of da yo ne and is great with colleagues. Among young people, honto sore, so true, is common slang; keep it for friends.

JapaneseRomajiMeaning
そうだね。Sō da ne.Yeah, that's right. (casual)
そうそう！Sō sō!Right, right! (casual)
だよね。Da yo ne.I know, right? (casual)
ですよね。Desu yo ne.Exactly, isn't it? (polite)
ほんとそれ。Honto sore.So true. (slang, friends only)

Tashika ni and ossharu tōri: agreeing with a point

Tashika ni (確かに) means certainly or indeed. On its own it says that's a fair point, and it is one of the most natural agreement words for learners because it works at almost any level of politeness. Tashika ni sō desu ne is a little warmer and more polite.

Sono tōri desu, that's exactly it, agrees firmly. Ossharu tōri desu uses the respectful verb ossharu, to say, and means it is just as you say. It is the standard way to agree with a boss, a client or a teacher, but with a friend it sounds stiff or even sarcastic.

Naruhodo, I see, is often used as if it meant I agree, but it really shows understanding. It is a useful listening word; just know that it does not commit you to the other person's view.

JapaneseRomajiMeaning
確かにそうですね。Tashika ni sō desu ne.That's certainly true.
その通りです。Sono tōri desu.That's exactly right.
おっしゃる通りです。Ossharu tōri desu.It's just as you say. (respectful)
なるほど、そういうことですね。Naruhodo, sō iu koto desu ne.I see, so that's what you mean.

Onaji iken desu and sansei desu: opinions and proposals

When people are sharing opinions, watashi mo onaji iken desu, I have the same opinion, is clear and polite. Onaji kangae desu, the same idea, is similar and slightly softer. Both work well in class discussions and meetings.

Sansei (賛成) is for proposals: something that a group will do or decide. Sansei desu means I'm in favour, and its opposite is hantai desu, I'm against it. It sounds odd as a reply to a feeling: if a friend says it's cold today, sansei desu sounds like a vote. Zenmenteki ni sansei desu, I fully support it, and iron wa arimasen, I have no objection, are useful formal versions.

JapaneseRomajiMeaning
私も同じ意見です。Watashi mo onaji iken desu.I have the same opinion.
山田さんの案に賛成です。Yamada-san no an ni sansei desu.I support Mr Yamada's proposal.
全面的に賛成です。Zenmenteki ni sansei desu.I fully support it.
異論はありません。Iron wa arimasen.I have no objection. (formal)

Partial agreement: yes, but

Real discussions are rarely all or nothing. Japanese has graceful ways to agree with part of something and leave room for your own view. Sō iu kangaekata mo arimasu ne, that's one way of looking at it, acknowledges the idea without fully adopting it. ~ to iu ten ni wa sansei desu, I agree on the point of ~, lets you pick the part you support.

The usual structure is agreement first, then tada, however, or demo, but, then your concern. Starting with agreement keeps the conversation friendly. Kimochi wa wakarimasu, I understand how you feel, is useful when you share the emotion but not the conclusion.

JapaneseRomajiMeaning
そういう考え方もありますね。Sō iu kangaekata mo arimasu ne.That's one way of looking at it.
コストの点には賛成です。Kosuto no ten ni wa sansei desu.I agree on the cost point.
ただ、時期は少し心配です。Tada, jiki wa sukoshi shinpai desu.However, I'm a bit worried about the timing.
気持ちはわかります。Kimochi wa wakarimasu.I understand how you feel.
半分は賛成です。Hanbun wa sansei desu.I half agree.

Agreeing in meetings

In a Japanese meeting, agreement is often expressed by naming the person and building on what they said. ~-san no go-iken ni sansei desu, I support ~'s view, is polite and clear. Tsukekuwaeru to, to add to that, lets you agree and contribute at the same time, which sounds more engaged than agreeing alone.

Silence and nodding are common in meetings, but they do not always mean agreement. If you do agree, say so in words, briefly, and give one reason. That makes your support count when the group decides.

A small team meeting around a table with coffee cups, where a South Asian woman raises her hand to support a colleague's idea
In meetings, name the person and add a reason: Tanaka-san no go-iken ni sansei desu, because...
JapaneseRomajiMeaning
田中さんのご意見に賛成です。Tanaka-san no go-iken ni sansei desu.I support Ms Tanaka's view.
私も同じ考えです。理由は二つあります。Watashi mo onaji kangae desu. Riyū wa futatsu arimasu.I think the same. There are two reasons.
付け加えると、予算も足ります。Tsukekuwaeru to, yosan mo tarimasu.To add to that, the budget is enough too.
では、その方向で進めましょう。Dewa, sono hōkō de susumemashō.Then let's go in that direction.

Softly not agreeing (briefly)

Disagreeing politely deserves its own guide, and the speaking practice article on disagreeing politely covers it in depth. The short version: start with partial agreement or a soft filler, then give your view as a suggestion or a question rather than a correction.

JapaneseRomajiMeaning
うーん、どうでしょう。Ūn, dō deshō.Hmm, I'm not sure about that.
少し違う意見なんですが。Sukoshi chigau iken nan desu ga.I have a slightly different view, but...
そうですね。ただ、別の案もあるかもしれません。Sō desu ne. Tada, betsu no an mo aru ka mo shiremasen.True. Though there may be another option.

Mini dialogue and common mistakes

JapaneseRomajiMeaning
来月から会議を朝にしませんか。Raigetsu kara kaigi o asa ni shimasen ka.Colleague: Shall we move meetings to mornings from next month?
賛成です。午後は忙しいですからね。Sansei desu. Gogo wa isogashii desu kara ne.You: I'm in favour. Afternoons are busy, after all.
ですよね。九時はどうですか。Desu yo ne. Ku-ji wa dō desu ka.Colleague: Right? How about nine?
確かに。ただ、月曜日だけは少し遅くしたいです。Tashika ni. Tada, getsuyōbi dake wa sukoshi osoku shitai desu.You: Good idea. Only, I'd like Mondays a bit later.
  • Dōi shimasu for everyday agreement: it means consent to terms. Use sō omoimasu or sansei desu.
  • Sansei desu for a feeling or a comment: it sounds like a vote. Use sō desu ne.
  • A long, falling sō desu nē when you mean yes: it sounds like hesitation.
  • Ossharu tōri desu with friends: too formal, and it can sound sarcastic.
  • Agreeing with only hai: hai often means I'm listening, not I agree.
Key points

A practical way to improve

Practise agreeing at four levels with one statement. Take kono purojekuto wa jikan ga kakarisō desu, this project looks like it will take time, and reply with sō da ne, tashika ni, watashi mo onaji iken desu, and ossharu tōri desu, saying each aloud with the right tone. Then add a reason to each: tashika ni, ninzū mo sukunai desu shi ne. Next, practise partial agreement: agree with one point and raise a concern with tada. Finally, open AI Sensei in Unihongo's immersive 3D classroom, choose the office meeting topic and ask the Sensei to play a colleague proposing a new schedule. Agree with one part, support another with sansei desu, and add one small concern politely. The session report will show which phrases you used and correct any that sounded off.

  1. 1

    Choose one clear goal

    Focus each session on a situation or skill you can actually use.

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

How do you say I agree in Japanese?

In conversation, say sō desu ne, that's right, or watashi mo sō omoimasu, I think so too. With friends, sō da ne or da yo ne. To agree with a proposal, say sansei desu, I'm in favour. To agree with a specific point, tashika ni, that's true, is very natural.

Can I say dōi shimasu for I agree?

Dōi (同意) means consent, as in agreeing to terms and conditions or giving formal approval. Dōi shimasu in a conversation sounds like signing a contract. Use sō omoimasu, onaji iken desu or sansei desu instead, depending on what you are agreeing with.

What is the difference between tashika ni and naruhodo?

Tashika ni means that's true and shows you agree with the point. Naruhodo means I see and shows you understand, without necessarily agreeing. Some people feel naruhodo sounds a little evaluating when said to a superior, so naruhodo desu ne or sō nan desu ne is a softer choice at work.

How do you agree politely with your boss in Japanese?

Ossharu tōri desu, it is just as you say, is the respectful phrase, and watashi mo sō omoimasu is a safe polite option. In a meeting, ~-san no go-iken ni sansei desu, I support Ms ~'s view, is clear and polite. Add a reason or detail so it does not sound automatic.
