Tsumori in Japanese: Intentions, Plans and I Thought I Had

Tsumori is a noun that means intention, and it attaches to verbs to say I intend to, I mean to or I plan to. It is one of the first ways learners talk about the future beyond the plain present tense, but it carries more nuance than a simple plan: it is firm, personal and sometimes defensive. The same word also appears in tsumori ja nakatta, I didn't mean to, and in ta tsumori, I thought I had, which are both common in apologies and everyday mix-ups. This guide covers how to form each pattern, how tsumori compares with the volitional ~ou to omou and with yotei, and why asking a superior about their tsumori can sound blunt.

Dictionary form plus tsumori desu states a fairly firm intention

Nai tsumori desu is the natural way to say you intend not to do something

Tsumori ja nakatta means I didn't mean to and softens an apology

Ta tsumori means I thought I had done it, or acting as if you had

What tsumori means

Tsumori, written つもり and usually in kana, is a noun meaning intention or expectation. Like other nouns, it can be modified by a verb in front of it, so iku tsumori is literally the intention to go. Adding desu turns it into a sentence: iku tsumori desu, I intend to go.

The nuance is that the decision is already made in your head. That makes tsumori sound more committed than simply saying ikimasu and more personal than talking about a schedule. It is ideal for goals, resolutions and plans you want to sound serious about.

Because it is about your inner intention, tsumori is mainly used for yourself. For other people, you usually report their intention with tsumori rashii or tsumori mitai, or ask them directly in casual speech.

JapaneseRomajiMeaning
来年、日本に留学するつもりです。Rainen, Nihon ni ryūgaku suru tsumori desu.I intend to study in Japan next year.
今日は早く寝るつもり。Kyō wa hayaku neru tsumori.I'm planning to go to bed early today. (casual)
週末は家でゆっくりするつもりです。Shūmatsu wa ie de yukkuri suru tsumori desu.I'm going to take it easy at home this weekend.
彼は会社を辞めるつもりらしい。Kare wa kaisha o yameru tsumori rashii.Apparently he's planning to quit his job.

Forming tsumori sentences

Tsumori follows the plain dictionary form for positive intentions and the nai form for negative ones. For the past, change desu to deshita, which gives you I had intended to, often implying the plan did not happen.

There are two negatives, and they mean different things. Ikanai tsumori desu, I intend not to go, is the everyday way to state a negative plan. Iku tsumori wa arimasen, I have no intention of going, is much stronger and often sounds like a firm refusal.

Past form + つもりです行ったつもりですI believe I went / as if I wentBelief or pretence
Casual: つもり / つもりだ行くつもりI'm planning to goFriends and family

Tsumori ja nakatta: I didn't mean to

When something you did had an effect you did not intend, tsumori ja nakatta explains that it was not your intention. It is common in apologies, particularly after a comment that came across badly.

On its own, it can sound like an excuse, so pair it with an apology. Sumimasen, sonna tsumori ja nakatta n desu, sorry, I didn't mean it that way, combines both and adds the explanatory n desu.

JapaneseRomajiMeaning
そんなつもりじゃなかったんです。Sonna tsumori ja nakatta n desu.I didn't mean it like that.
怒らせるつもりはなかったんだ。ごめん。Okoraseru tsumori wa nakatta n da. Gomen.I didn't mean to make you angry. Sorry.
傷つけるつもりじゃなかった。Kizutsukeru tsumori ja nakatta.I didn't mean to hurt you.
こんなに遅くなるつもりじゃなかったんですが。Konna ni osoku naru tsumori ja nakatta n desu ga.I didn't intend to be this late...
冗談のつもりだったんです。Jōdan no tsumori datta n desu.I meant it as a joke.

The last example shows that tsumori can also follow a noun with no: jōdan no tsumori, meant as a joke, or shinsetsu no tsumori, meant as a kindness.

Ta tsumori: I thought I had

When tsumori follows the past tense, the meaning changes from intention to belief. Kagi o kaketa tsumori datta, I thought I had locked the door, describes a gap between what you believed and what actually happened. This is extremely common for everyday slips.

The same pattern describes acting as if something were true. Ryokō shita tsumori de chokin suru means saving money as if you had gone on the trip, and wakai tsumori means thinking of yourself as young.

Adjectives and nouns work too: genki na tsumori, thinking you are fine, or senmonka no tsumori, acting like an expert, which is often slightly critical.

JapaneseRomajiMeaning
鍵をかけたつもりだったんですが。Kagi o kaketa tsumori datta n desu ga.I thought I had locked it...
メールを送ったつもりでした。Mēru o okutta tsumori deshita.I was sure I had sent the email.
ちゃんと説明したつもりなんですけど。Chanto setsumei shita tsumori na n desu kedo.I thought I had explained it properly.
旅行に行ったつもりで貯金する。Ryokō ni itta tsumori de chokin suru.I'll save the money as if I'd gone on the trip.
自分ではまだ若いつもりです。Jibun de wa mada wakai tsumori desu.In my own mind I'm still young.

Tsumori vs ~ou to omou vs yotei

Japanese has several ways to talk about future plans, and choosing the right one changes how committed you sound. For the wider picture of talking about the future, it helps to think of these three as a scale from soft idea to fixed arrangement.

~ou to omou, formed with the volitional, means I'm thinking of doing. In the te iru form, ~ou to omotte imasu, it describes an idea you have been considering for a while. It is soft and modest, and it is often the most natural choice in polite conversation about your own plans.

Tsumori is firmer: the decision is made. Yotei is a schedule, something arranged or fixed, often involving other people, dates or bookings. It can also describe official plans that have nothing to do with personal intention, such as a train's scheduled arrival.

FormExampleFeels likeBest for
~ou to omotte imasu転職しようと思っていますI'm thinking of changing jobsIdeas still forming, modest tone
~tsumori desu転職するつもりですI intend to change jobsDecided personal plans
~yotei desu来月転職する予定ですI'm scheduled to change jobs next monthArranged, fixed plans
Plain masu form来月転職しますI'm changing jobs next monthSimple statement of fact

Yotei also works for things outside your control: densha wa jūji ni tsuku yotei desu, the train is due to arrive at ten. Tsumori could never be used there, because a train has no intentions.

Asking about someone's intentions

Asking a friend what they plan to do with tsumori is fine in casual speech: dō suru tsumori? what are you going to do? But with the wrong tone, the same question can sound confrontational, like what exactly do you think you are doing?

In polite speech, especially to someone senior, avoid tsumori desu ka. Ask about yotei instead, with the honorific go- prefix, or use a neutral question. This protects the other person from feeling that you are questioning their judgement.

JapaneseRomajiMeaning
夏休みはどうするつもり?Natsuyasumi wa dō suru tsumori?What are you planning to do over summer break? (casual)
週末のご予定は?Shūmatsu no go-yotei wa?Do you have any plans for the weekend? (polite)
部長は明日いらっしゃいますか。Buchō wa ashita irasshaimasu ka.Will the department manager be in tomorrow? (polite)
一体どういうつもりですか。Ittai dō iu tsumori desu ka.What on earth do you mean by this? (angry)

Common learner mistakes

  • Using the masu form before tsumori: ikimasu tsumori is wrong; use iku tsumori desu.
  • Using tsumori for events you don't control, such as weather or trains. Use yotei or deshō instead.
  • Saying tsumori wa arimasen when you mean a neutral negative plan; ikanai tsumori desu is usually softer.
  • Using tsumori for every plan in a job interview, which can sound rigid. Mix in ~ou to omotte imasu and kangaete imasu.
  • Confusing ta tsumori with a past intention: itta tsumori means I thought I went, while iku tsumori deshita means I had meant to go.
Key points

A practical way to improve

Say three intentions for next month with tsumori desu, one with nai tsumori desu, and one softer version of each using ~ou to omotte imasu. Then describe a small mistake using ta tsumori, such as believing you had locked the door. Finally, ask your AI Sensei in Unihongo's immersive 3D classroom to run the Japanese Job Interview mission and answer the question about your future plans, choosing between tsumori, yotei and ~ou to omotte imasu. Afterwards, check the session report to see whether your choice matched the tone of an interview.

FAQ

Frequently asked questions

What is the difference between tsumori and yotei?

Tsumori is your personal intention, what you have decided in your own mind. Yotei is a schedule or arrangement, often involving other people or fixed times. Raishū Kyōto ni iku tsumori desu is your intention; raishū Kyōto ni iku yotei desu sounds like it is already arranged.

Is tsumori stronger than ~ou to omou?

Usually, yes. Tsumori desu sounds like a decided intention, while ikou to omotte imasu, I'm thinking of going, sounds softer and less fixed. In polite conversation about your own plans, the ~ou to omotte imasu form is often the gentler choice.

Can I ask my boss what they intend with tsumori?

It is best avoided. Dō suru tsumori desu ka can sound like you are questioning their intentions, almost like what do you think you are doing? Ask about plans with go-yotei or a polite question such as dō nasaimasu ka instead.

How do I say I didn't mean to in Japanese?

Say sonna tsumori ja nakatta n desu, I didn't mean it like that, or the more specific verb plus tsumori ja nakatta. Follow it with an apology, because on its own it can sound like you are making an excuse.
