Use つもりです for a decision you’ve made in your own head, 予定です once it’s actually arranged with a date or booking, and つもりでした when that plan changed or fell through.
This guide is for N5-N4 learners who keep mixing up つもり and 予定. After reading, you will know exactly which one to pick, and why native speakers switch between them mid-sentence.
Quick summary: つもりです is a private decision, 予定です is a booked plan, and つもりでした means the plan didn’t happen as intended.
| Form | What’s really being said | How fixed is it? |
|---|---|---|
| 〜つもりです | A decision you’ve made for yourself | Not necessarily arranged with anyone else yet |
| 〜予定です | Something already set on a schedule | Usually has a date, booking, or agreement attached |
| 〜つもりでした | A decision you had — until things changed | Signals the plan didn’t happen as intended |

Why つもりです Doesn’t Mean What “I Will” Means in English
The English “I Will” Hides Three Different Japanese Ideas
In English, “I will” does a lot of jobs at once. It can predict the weather, make a promise, or state a personal plan.
Because one word covers all three, learners reach for “I will” or “I’m planning to” in almost every situation. Japanese doesn’t work that way.
つもりです marks a decision you made for yourself. It’s not a guess about the future, and it’s not a fact you’ve arranged with anyone else.
つもり is like a sticky note only you can see — it states what you’ve decided, but nothing outside your own head has confirmed it. 予定 is like an entry already written in ink in a shared calendar, with a date, booking, or agreement attached.
This picture breaks down at one point. Telling someone your つもり doesn’t turn it into 予定.
Sharing the decision isn’t what changes it. 予定 leans on something outside your own head — a date, a booking, or an agreement with someone else — while つもり stays inside it.
The One-Question Test: つもりです or 予定です?
Ask Yourself: Is It Fixed on a Schedule, or Just Fixed in My Head?
Ask yourself: “Could I already tell someone exactly when or where this happens, because it’s arranged?” If yes, use 予定です. If it’s still just what you’ve personally decided, with nothing booked yet, use つもりです.
Say you want to visit Osaka someday. No tickets, no dates, just an idea. That’s 大阪に行くつもりです.
Now say you’ve bought the train ticket for next Friday. Someone could ask “what time do you leave?” and you’d have a real answer. That’s 大阪に行く予定です.
つもりです for Decisions Nobody Else Has Confirmed Yet
Your Own Resolve, Not Anyone Else’s Calendar
つもり works fine for vague or far-off goals. There’s no set date, no booking, just your own resolve.
It’s especially common when you explain your reasoning. For example, when you’re turning down an invitation, つもり tells people why, without needing any outside proof.
Japanese: 週に三回、ジムに通うつもりです。
Romaji: Shuu ni sankai, jimu ni kayou tsumori desu.
English: I’m planning to go to the gym three times a week.
Why: A personal resolve with no fixed schedule attached yet — pure つもり.
Japanese: 今夜は誘ってくれてありがとう。でも、今日は早めに寝るつもりなんだ。
Romaji: Kon’ya wa sasotte kurete arigatou. Demo, kyou wa hayame ni neru tsumori nanda.
English: Thanks for inviting me tonight. But I’m planning to go to bed early today.
Why: つもり explains a private decision used as the reason for declining — nothing arranged, just your own call.
予定です for Anything Already on the Calendar
Once It’s Booked, Agreed, or Arranged, It’s 予定, Not つもり
予定 shows the plan is tied to something real outside your head. That could be a reservation, a ticket, an appointment, or an agreement with another person.
Switching from つもり to 予定 mid-conversation is completely natural. It’s how native speakers show a plan just became real.
Japanese: 来週、もう一泊する予定です。もう予約も入れました。
Romaji: Raishuu, mou ippaku suru yotei desu. Mou yoyaku mo iremashita.
English: I’m scheduled to stay one more night next week. I’ve already made the reservation.
Why: 予定 shows a plan backed by a real booking, not just a personal intention.
つもりでした: When Your Plan Didn’t Happen
Why the Past Tense Changes Everything
つもりでした doesn’t just mean “I intended to.” It usually signals the plan changed, or fell through completely.
English speakers often forget to shift the tense. That leaves the sentence sounding like the plan is still happening, which confuses the listener.
今日は早く帰るつもりです。でも、仕事が終わらなくて残業しました。
今日は早く帰るつもりでした。でも、仕事が終わらなくて残業したんです。
English naturally shifts the intention to past tense when reporting a failure, as in “I was going to leave early.” Learners often keep the present-tense つもりです they learned first, and forget to change it.
Common Mistake:来週、友達と京都に旅行するつもりです。（もう新幹線のチケットも買った）This keeps つもり even after a ticket is already bought. Once a ticket, reservation, or date is attached, switch to 予定: 来週、友達と京都に旅行する予定です。もう新幹線のチケットも買いました。
Frequently Asked Questions about つもりです
Can I use つもりです for a firm decision, even without a booking?
Yes. つもりです can sound very firm, even without any booking attached. Firmness and outside confirmation are two separate things in Japanese.
Is 予定です more polite than つもりです?
Not really. Both are equally polite in the ます/です form. The difference is about whether the plan is arranged, not about politeness level.
What happens if I use つもりです after already booking something?
It’s not a grave error, but it sounds a little off to a native ear. Once a ticket or reservation exists, 予定です fits the situation better.
Quick Quiz: つもりです, 予定です, or つもりでした?
Fill in the blank with the correct form. Check your answers below once you’re done.
- 来月、大阪に出張する＿＿＿。もうホテルも予約しました。
- いつか日本に住む＿＿＿。まだ何も決めていません。
- 今朝、早く起きる＿＿＿。でも目覚まし時計が鳴らなくて、遅刻しました。
1. 予定です – A hotel reservation is already made, so the plan is fixed on a schedule.
2. つもりです – Nothing is decided yet beyond a personal wish, so this stays in your head.
3. つもりでした – The plan to wake up early failed, so the past tense shows it fell through.
Summary: Keep the Sticky Note and the Calendar Separate
- つもりです marks a decision made in your own head, with nothing booked yet.
- 予定です marks a plan attached to a real date, ticket, or agreement.
- つもりでした signals a plan that changed or didn’t happen as intended.
- Telling someone your つもり doesn’t turn it into 予定 — only a real detail does that.
Once you’re comfortable switching between these three forms, you’re ready to look at how Japanese handles plans that depend on someone else’s decision, not just your own.
