Why does Japanese need four different words for “appointment”? In English I just say “I have plans” for almost everything!
Rei
That is a great question! Japanese draws a clear line between securing a slot at a place (予約), having something on your calendar (予定), making a personal commitment to another person (約束), and arranging a formal business meeting (アポイント). Once you see each word’s territory, you will never mix them up again.
## What Does 予約 Mean? 予約（よやく）means a **reservation or booking** — the act of securing a specific time slot, seat, room, or service in advance. The core idea of 予約 is that you are claiming something. You are telling a restaurant, hotel, hospital, or service provider: “Hold that spot for me.” Without 予約, you might not get in at all. **Common 予約 expressions:** – 予約を入れる（よやくをいれる）— to make a reservation (lit. “to put in a reservation”)
– 予約を取る（よやくをとる）— to secure/get a reservation
– 予約をキャンセルする — to cancel a reservation
– 予約を変更する（よやくをへんこうする）— to change/modify a reservation
– 予約確認メール（よやくかくにんメール）— reservation confirmation email **Example sentences:** レストランの予約を入れました。
*I made a restaurant reservation.* ホテルを予約しましたか？
*Did you book a hotel?* 病院（びょういん）の予約が午後2時です。
*My doctor’s appointment is at 2 p.m.* (Note: hospital bookings in Japanese are also 予約, not アポイント.) 美容院（びよういん）の予約をキャンセルしてもいいですか？
*Is it okay if I cancel my hair salon reservation?* **Compound words using 予約:** – 予約席（よやくせき）— reserved seat
– 予約制（よやくせい）— reservation-only system
– 事前予約（じぜんよやく）— advance booking
– 満席（まんせき）— fully booked (no more reservations accepted) The key thing to remember: 予約 always involves a service provider or venue. You are reserving a resource — a table, a room, a time slot with a doctor — not simply planning to do something. ## What Does 予定 Mean? 予定（よてい）means a **plan or schedule** — something you intend to do or something already on your calendar. Unlike 予約, 予定 does not require anyone else to be involved. You can have a 予定 that is entirely solo. “I plan to study on Saturday” is a 予定. “I plan to go to the gym” is a 予定. It simply means something is on your agenda. **Common 予定 expressions:** – 予定がある（よていがある）— to have plans / to be busy (lit. “there is a plan”)
– 予定を入れる（よていをいれる）— to schedule something / to put something in your calendar
– 予定を変更する（よていをへんこうする）— to change plans
– 今日の予定（きょうのよてい）— today’s schedule / plans for today
– 予定通り（よていどおり）— as planned / according to schedule **Example sentences:** 今日は予定があります。
*I have plans today.* (Could be solo; no other person implied.) 来週の予定を教えてもらえますか？
*Could you tell me your schedule for next week?* 旅行の予定を立てました（たてました）。
*I made travel plans.* 会議（かいぎ）の予定が変わりました。
*The meeting schedule has changed.* 予定通りに進んでいます。
*Things are progressing as planned.* **Compound words using 予定:** – 予定表（よていひょう）— schedule sheet / planner
– 予定日（よていび）— scheduled date / due date
– 未定（みてい）— undecided / not yet scheduled One nuance worth noting: when a Japanese person says 予定があります as a polite refusal, it is equivalent to the English “I have plans.” It is intentionally vague — they are not obligated to explain what the plan is. ## What Does 約束 Mean? 約束（やくそく）means a **promise or mutual arrangement between two or more people**. This is the word that most closely captures the interpersonal weight of “I promised to meet someone.” 約束 is not just a calendar entry — it is a commitment to another person. Breaking a 約束 carries real social weight in Japanese culture. **Common 約束 expressions:** – 約束をする（やくそくをする）— to make a promise / to arrange to meet
– 約束がある（やくそくがある）— to have an arrangement with someone
– 約束を守る（やくそくをまもる）— to keep a promise
– 約束を破る（やくそくをやぶる）— to break a promise
– 約束の時間（やくそくのじかん）— the agreed time / the promised time **Example sentences:** 友達と約束があります。
*I have plans with a friend.* (Implies a mutual arrangement — there is another person involved.) 彼は約束を守らなかった。
*He did not keep his promise.* 明日の3時に会う約束をしました。
*We arranged to meet at 3 o’clock tomorrow.* 子供（こども）に約束したから、守らないといけない。
*I promised my child, so I have to keep it.* いつも約束を破る人は信用（しんよう）できない。
*You cannot trust a person who always breaks promises.* **Compound words using 約束:** – 口約束（くちやくそく）— verbal promise (lit. “mouth promise”)
– 取り決め（とりきめ）— agreement / arrangement (more formal synonym) The key distinction: 約束 is always between people. You cannot make a 約束 with a restaurant. You make a 予約 with a restaurant and a 約束 with a friend to go there together.
Yuka
So if I say 友達と予定があります and 友達と約束があります — aren’t both saying “I have plans with a friend”? What is the real difference?
Rei
Both sentences work, but the nuance is slightly different. 予定があります simply says something is on your schedule — it is a neutral, factual statement. 約束があります says you specifically made a commitment to meet that person — there is a mutual agreement involved. In casual speech, both are used naturally, but 約束 carries a stronger sense of “I promised them I would be there.”
## What Does アポイント Mean? アポイント is a loanword from English “appointment,” but in Japanese it is used **exclusively in business contexts** — specifically for arranging a formal meeting with a client, business partner, or external party. In everyday Japanese, アポイント (often shortened to just アポ) is the word you use when a salesperson calls a company, when you schedule a meeting with a client, or when you arrange an interview. It does not sound natural when used between friends. **Full forms and variants:**
– アポイント — the standard business shorthand
– アポ — the casual shortened form, still business-specific
– アポイントメント — the fuller loanword form, used in formal writing **Common アポイント expressions:** – アポを取る — to arrange a business appointment (the most common expression)
– アポなし — without a prior appointment (e.g., アポなしで訪問する — to visit without an appointment)
– アポをリスケする — to reschedule an appointment (business slang; リスケ = reschedule)
– 取引先（とりひきさき）とのアポイント — an appointment with a client / business partner **Example sentences:** 明日、取引先とのアポがあります。
*I have an appointment with a client tomorrow.* アポなしでの訪問はご遠慮ください。
*Please refrain from visiting without a prior appointment.* アポを取るために電話しました。
*I called to arrange an appointment.* 担当者（たんとうしゃ）とアポイントを入れてもいいですか？
*May I schedule an appointment with the person in charge?* ⚠️ Using アポ with friends sounds unnatural and overly corporate. If you want to say “let’s make plans to hang out,” use 約束 or 予定. Reserve アポ/アポイント for business and formal contexts only. **Compound words and related business terms:** – アポ取り（アポとり）— the act of setting up appointments (a key task in Japanese sales jobs)
– 商談（しょうだん）— business negotiation / sales meeting
– 打ち合わせ（うちあわせ）— informal work meeting / briefing ## 予約 vs 予定: Securing a Slot vs Having a Plan The confusion between these two is common for beginners because both can translate as “booking” in English. The key difference: **予約 secures a resource at a venue; 予定 is simply an entry on your own calendar.** Think of it this way: when you make a 予約, someone on the other end of the transaction holds something for you. When you have a 予定, you are the only one who knows about it. | | 予約 | 予定 |
|—|—|—|
| Involves another party holding something for you | ✅ Yes | ❌ No |
| Can be solo | ❌ No | ✅ Yes |
| Used for restaurants, hotels, hospitals | ✅ Yes | ❌ No |
| Used for general calendar entries | ❌ No | ✅ Yes | An important relationship between these two words: **a 予約 becomes part of your 予定**. Once you book a restaurant, that booking (予約) appears on your schedule (予定). Both words can be true at the same time, but they describe different aspects. **Natural examples showing the difference:** レストランを予約した。その日は予定がある。
*I made a restaurant reservation. I have plans on that day.* 土曜日の予定は？ — レストランの予約が入ってる。
*What are your plans for Saturday? — I have a restaurant reservation.* **Common mistake:** Saying 予定を取る for “making a reservation.” 取る (to take/get) collocates with 予約 — 予約を取る is natural. For 予定, you use 予定を立てる (to make plans) or 予定を入れる (to schedule something). ## 予定 vs 約束: Personal Schedule vs Interpersonal Promise Both 予定 and 約束 can be translated as “plans” in English, which is why learners often use them interchangeably. The distinction is all about whether another person is involved in a **mutual commitment**. – 予定 = something on your calendar. Could be solo. No obligation to another person implied.
– 約束 = a commitment made to another person. Both parties agreed. Breaking it is socially significant. **Compare these pairs:** 今日は予定があります。
*I have plans today.* (Could be anything — errands, study, going for a walk alone.) 今日は友達と約束があります。
*I have plans with a friend today.* (Implies a mutual commitment — they are expecting you.) — 土曜日は何か予定ある？
*Do you have anything going on Saturday?* (Casual, asking about your schedule.) 土曜日に会う約束してたよね？
*We had plans to meet on Saturday, right?* (Reminder of a mutual commitment.) **When both could work — and when only one is correct:** Meeting a friend → both 予定がある and 約束がある work, but 約束がある emphasizes the commitment more strongly. Solo study session → only 予定がある is correct. You cannot make a 約束 with yourself. Saying you will definitely do something for someone → 約束する is required. 予定する sounds clinical and impersonal. ## 予約 vs アポイント: Service Booking vs Business Meeting Both 予約 and アポイント involve arranging a time with another party — so what is the difference? The difference is **the nature of the transaction and who you are meeting**. – 予約 = you are securing a service, a room, a table, or a time slot. The other party is a venue, a service provider, or a business you are paying.
– アポイント = you are arranging a formal meeting with a business contact. Both parties are equal participants in the meeting. **The rule of thumb:** If you are a customer booking a service, use 予約. If you are a business professional arranging a meeting with another professional, use アポイント. | Situation | Correct Word | Example |
|—|—|—|
| Booking a restaurant table | 予約 | レストランの予約を取る |
| Reserving a hotel room | 予約 | ホテルを予約する |
| Scheduling a doctor visit | 予約 | 病院の予約を入れる |
| Booking a hair salon | 予約 | 美容院を予約する |
| Meeting a business client | アポイント | 取引先とのアポを取る |
| Job interview scheduling | アポイント | 面接（めんせつ）のアポイントを入れる | **Common mistake:** Using アポイント for all types of “appointments.” In Japan, visiting a doctor or dentist is a 予約, not an アポイント — even though English speakers call both an “appointment.” アポイント is reserved for the corporate world. ## Appointment Words by Situation Here is a complete reference for which word to use depending on what you are trying to say: | Situation | Word to Use | Example Phrase |
|—|—|—|
| Restaurant reservation | 予約（よやく）| レストランを予約する |
| Hotel booking | 予約（よやく）| ホテルを予約する |
| Doctor / hospital appointment | 予約（よやく）| 病院の予約を取る |
| Hair salon booking | 予約（よやく）| 美容院の予約を入れる |
| Train / flight seat reservation | 予約（よやく）| 新幹線（しんかんせん）を予約する |
| Casual meetup with a friend | 約束（やくそく）| 友達と会う約束をする |
| Solo plan or personal schedule item | 予定（よてい）| 予定を入れる |
| Group plan (mentioned to others) | 予定（よてい）| 週末（しゅうまつ）の予定がある |
| Business meeting with a client | アポイント | 取引先のアポを取る |
| Meeting with an external consultant | アポイント | コンサルタントとアポを入れる |
| Online consultation (business) | アポイント | オンラインでアポイントを取る |
| Online consultation (medical) | 予約 | オンライン診療（しんりょう）の予約をする | Note: Medical consultations — even online ones — use 予約, not アポイント, because you are booking a service from a provider, not arranging a peer meeting. ## Changing, Canceling, and Confirming Plans Knowing how to change or cancel a plan is just as important as making one. Each of the four words has its own natural verb phrases for adjustments: **予約 (reservation):** 予約を変更したいのですが。
*I would like to change my reservation.* 予約をキャンセルしてもいいですか？
*May I cancel my reservation?* 予約の確認メールをお送りします。
*We will send you a reservation confirmation email.* **予定 (plan/schedule):** 予定を変更しました。
*I changed my plans.* 予定が入ってしまいました。
*Something came up on my schedule.* (A common, polite way to say you are newly unavailable.) 予定通りに行きます。
*I will go as planned.* **約束 (promise/arrangement):** 約束を延期（えんき）してもいいですか？
*Would it be okay to postpone our plans?* 約束を守れなくてごめんなさい。
*I am sorry I could not keep my promise.* また約束しましょう。
*Let us make plans again.* **アポイント (business appointment):** アポをリスケしてもいいでしょうか？
*Would it be possible to reschedule our appointment?* (リスケ = reschedule, business slang) アポイントの変更をお願いしたいのですが。
*I would like to request a change to our appointment.* 明日のアポを確認させてください。
*Let me confirm tomorrow’s appointment.*
Yuka
What is the most natural and polite way to tell a friend you need to reschedule your plans? I do not want to sound too stiff.
Rei
With a friend, a natural and warm phrasing is: 急で悪いんだけど、約束の日を変えてもいい？ (I know this is sudden, but is it okay to change the day we planned?) Or more casually: ちょっと予定が入っちゃって、延期できる？ (Something came up — can we postpone?) Avoid リスケ with friends — it is very corporate-sounding and can come across as cold.
## Common Mistakes English Speakers Make **Mistake 1: Translating every “appointment” as アポイント** In English, “appointment” covers doctors, dentists, meetings, and more. In Japanese, アポイント is only for business. Medical visits use 予約. Hair salon visits use 予約. アポイント at a clinic would sound strange to a Japanese receptionist. ❌ 歯医者（はいしゃ）のアポイントを取りました。
✅ 歯医者の予約を取りました。
*I made a dentist appointment.* **Mistake 2: Saying レストランの約束 instead of レストランの予約** This is the error mentioned at the start of this article. Restaurants get 予約, not 約束. 約束 is between people; 予約 is with a venue. ❌ 友達とレストランの約束をした。
✅ 友達とレストランの予約をした。
*I made a restaurant reservation with my friend.* **Mistake 3: Using 約束 for solo plans** 約束 requires another person. If you are simply blocking out time for yourself, use 予定. ❌ 土曜日に図書館（としょかん）で勉強する約束があります。
✅ 土曜日に図書館で勉強する予定があります。
*I plan to study at the library on Saturday.* **Mistake 4: Using アポ with friends** アポ sounds corporate. Among friends, it signals that you are treating the relationship like a business transaction. ❌ 週末に友達とアポがあります。
✅ 週末に友達と約束があります。
*I have plans with a friend on the weekend.* **Mistake 5: Confusing 予定があります and 予約があります** Both can be natural, but they mean different things. 予約があります specifically means “I have a reservation somewhere.” 予定があります means “I have something scheduled.” Using 予約があります when you just mean “I’m busy” sounds odd — as if you are implying you have booked a specific venue. ❌ 今日は予約があるから行けない。(when you just mean you’re busy)
✅ 今日は予定があるから行けない。
*I can’t go today because I have plans.* ## Decision Rule: Which Schedule Word Should You Use? “`
Are you securing a seat, room, service slot, or time with a venue?
YES → 予約（よやく）
Example: restaurant, hotel, hospital, hair salon, shinkansen seat NO → Is this a commitment you made to another specific person?
YES → 約束（やくそく）
Example: “I promised my friend I would meet them” NO → Is this a formal business meeting with a client or external party?
YES → アポイント（アポ）
Example: sales call, client visit, job interview NO → 予定（よてい）
Example: your own schedule, personal plans, general “I have plans”
“` A shortcut to remember:
– **Venue holds something for you** → 予約
– **You promised another person** → 約束
– **Corporate / external business meeting** → アポイント
– **Everything else on your calendar** → 予定 ## Quick Quiz Test yourself with these five questions. Choose the correct word from the options given. **Question 1:** You are calling a popular ramen restaurant to book a table for two this Friday. You say: a) 約束を取りたいのですが。
b) 予約を取りたいのですが。
c) アポイントを取りたいのですが。 **Answer: b) 予約を取りたいのですが。** — You are booking a service at a venue, so 予約 is correct. — **Question 2:** Your colleague mentions they are free on Thursday. You say: “I have a client meeting Thursday afternoon.” Which word fills the blank? 木曜日の午後は取引先との___があります。 a) 予定
b) 約束
c) アポイント **Answer: c) アポイント** — A meeting with a client (取引先) is exactly the domain of アポイント. — **Question 3:** Your Japanese friend asks what you are doing this weekend. You say: “I have plans with a friend on Saturday.” Which is the most natural sentence? a) 土曜日は友達と予約があります。
b) 土曜日は友達と約束があります。
c) 土曜日は友達とアポがあります。 **Answer: b) 土曜日は友達と約束があります。** — A personal arrangement with a friend is 約束. Using アポ with a friend sounds corporate; using 予約 implies you reserved a table at some venue. — **Question 4:** You already had something scheduled and need to tell a colleague you cannot join their meeting. You say: “Sorry, I have plans at that time.” Which word completes this most naturally? その時間はすでに___があります。すみません。 a) 予約
b) アポイント
c) 予定 **Answer: c) 予定** — You are referring to an existing calendar entry in general terms. 予定があります is the standard, neutral way to say “I have something scheduled.” — **Question 5:** Your dentist’s receptionist calls to confirm your upcoming visit. She says: 明日の___の確認のお電話です。 a) アポイント
b) 予約
c) 約束 **Answer: b) 予約** — Medical visits, including dental appointments, are always 予約 in Japanese, not アポイント. — How did you do? If you got all five right, you have a solid grasp of all four words. If any caught you off guard, go back and re-read the section for that word — the situation tables and common mistakes sections are especially helpful for locking in the distinctions.
