予約 vs. 申し込み: What Is the Difference in Japanese?

Introduction

Japanese learners often confuse 予約 (yoyaku / reservation or booking) and 申し込み (mōshikomi / application or registration).

Both words describe something you do before using a service or joining an activity. However, their purposes are different.

Do you want to secure a seat, room, or time slot? Or do you want to officially express your intention to participate or use a service?

Once you understand this difference, choosing the correct word becomes much easier.

The Difference in One Sentence

予約 (yoyaku) means securing a seat, room, time slot, product, or service in advance.

申し込み (mōshikomi) means officially requesting to participate in an event, take an examination, or use a service.

An easy way to remember the difference is:

予約 means “save it for me.”
申し込み means “I would like to participate or use it.”

Understanding 予約

予約 Means Securing Something in Advance

予約 (yoyaku / reservation or booking) is used when you arrange in advance to secure something you plan to use later.

Common things you can reserve include:

• A restaurant table
• A hotel room
• A doctor’s appointment
• A time slot at a hair salon
• A seat on a train or airplane
• A product that has not yet been released

The central idea behind 予約 is that a place, time, product, or service is being kept available for you.

For example, when you reserve a restaurant, a table is set aside for you. When you make a hospital appointment, a particular time is allocated for your visit.

That is why 予約 is strongly connected with specific places, times, seats, rooms, and services.

Understanding 申し込み

申し込み Means Applying or Registering

申し込み (mōshikomi / application or registration) refers to expressing your intention to participate in an activity or use a service and then completing the required procedure.

Common examples include:

• Registering for a seminar
• Applying to take the JLPT
• Enrolling in a Japanese course
• Signing up for an online service
• Applying for a credit card
• Entering a campaign or competition

The verb form is 申し込む (mōshikomu / to apply or register).

Unlike a reservation, an application does not always guarantee acceptance.

For example, an event may select participants by lottery after applications close. A credit card company may review your application before approving it.

The main idea behind 申し込み is:

You express your wish and begin an official procedure.

When to Use Each Word

Use 予約 for Restaurants, Hotels, Hospitals, and Salons

In daily life, 予約 is frequently used when you need to secure a particular place or time.

Common expressions include:

• レストランを予約する
  Reserve a restaurant table.

• ホテルの部屋を予約する
  Reserve a hotel room.

• 病院の診察を予約する
  Make a doctor’s appointment.

• 美容院を予約する
  Book an appointment at a hair salon.

• 飛行機の座席を予約する
  Reserve an airplane seat.

When the important question is “At what time?” or “Which seat or room?”, 予約 is usually the correct choice.

Use 申し込み for Events, Examinations, and Services

Use 申し込み when you complete a procedure to participate in something or begin using a service.

Common expressions include:

• セミナーに申し込む
  Register for a seminar.

• 試験に申し込む
  Apply to take an examination.

• 日本語講座に申し込む
  Enroll in a Japanese course.

• ツアーに申し込む
  Sign up for a tour.

• 新しいサービスに申し込む
  Apply for a new service.

When you are telling an organization, “I would like to participate” or “I would like to use this service,” 申し込み is the natural choice.

How They Are Used in Business

In business situations, 申し込み is common when discussing contracts, registrations, or the beginning of a service.

• 新しい料金プランに申し込む。
  Apply for a new pricing plan.

• オンラインサービスの利用を申し込む。
  Apply to use an online service.

• 研修への参加を申し込む。
  Register to participate in a training program.

• 資料の送付を申し込む。
  Request that informational materials be sent.

By contrast, 予約 is used when securing a meeting room, appointment time, or accommodation.

• 会議室を予約する。
  Reserve a meeting room.

• 面談の時間を予約する。
  Book a time for an interview or consultation.

• 出張先のホテルを予約する。
  Reserve a hotel for a business trip.

Examples with 予約

Example 1

来週の金曜日に、駅前のレストランを予約しました。
I reserved a restaurant near the station for next Friday.

This sentence means that a table has been secured in advance for Friday.

Example 2

明日の午前10時に、病院の診察を予約しています。
I have a doctor’s appointment tomorrow at 10:00 a.m.

A specific time has been arranged for the speaker to see a doctor.

Example 3

旅行の前に、ホテルと飛行機を予約しておきましょう。
Let’s reserve the hotel and flights before the trip.

The speaker suggests securing the room and airplane seats in advance.

The pattern ～ておく (te oku) expresses doing something in preparation for the future.

Example 4

人気の商品なので、発売前に予約しました。
Because it is a popular product, I pre-ordered it before its release.

Here, 予約 means ensuring that one unit of the product will be kept for the buyer.

Example 5

美容院を予約したいのですが、土曜日の午後は空いていますか。
I would like to book an appointment at the hair salon. Do you have any openings on Saturday afternoon?

The speaker wants to choose and secure an available time.

Examples with 申し込み

Example 1

来月の日本語能力試験に申し込みました。
I registered for next month’s Japanese-Language Proficiency Test.

The speaker completed the procedure required to take the examination.

Example 2

会社の研修に参加したい人は、金曜日までに申し込んでください。
Anyone who wants to participate in the company training should register by Friday.

The participants must express their intention to join and complete the required registration.

Example 3

インターネットで日本語講座に申し込みました。
I enrolled in a Japanese course online.

The speaker provided the necessary information and completed the enrollment procedure.

Example 4

このサービスは、ウェブサイトから申し込むことができます。
You can apply for this service through the website.

The sentence explains how to begin the application or registration process.

Example 5

定員を超えた場合は、申し込んだ人の中から抽選で参加者を決めます。
If the number of applicants exceeds the limit, participants will be selected by lottery.

This example shows an important feature of 申し込み: applying does not always mean that participation is guaranteed.

When Both 申し込み and 予約 Are Necessary

Some services require both an application and a reservation.

Imagine that you want to attend a trial lesson at a Japanese language school.

First, you submit an application to participate. After your application is accepted, you choose and reserve a specific lesson time.

The process may look like this:

• Express your wish to participate
• Submit an application
• Select an available date and time
• Reserve the time slot

In Japanese:

体験授業に申し込んだ後で、授業の日時を予約しました。
After applying for the trial lesson, I reserved the date and time of the class.

In this sentence, 申し込む refers to the participation procedure, while 予約する refers to securing a specific date and time.

The same distinction can appear with online services. You may first apply for membership and then reserve a consultation or lesson.

Common Mistakes

Mistake 1: レストランに申し込む

Unnatural:

レストランに申し込みました。
I applied to the restaurant.

This sounds unnatural when you simply want to eat at the restaurant. Normally, you are not applying for permission to participate. You are securing a table.

Natural:

レストランを予約しました。
I reserved a restaurant table.

However, if the restaurant is organizing a special event or cooking class, 申し込む may be correct.

レストランの料理教室に申し込みました。
I registered for the restaurant’s cooking class.

Here, you are applying to participate in an event rather than reserving a table.

Mistake 2: JLPTを予約する

Usually unnatural:

JLPTを予約しました。
I reserved the JLPT.

Applicants do not normally choose and secure a personal seat or time slot. They complete an official registration procedure.

Natural:

JLPTに申し込みました。
I registered for the JLPT.

However, some examinations allow candidates to choose a specific test time. In that situation, both words may appear at different stages.

• 試験に申し込む。
  Apply to take the examination.

• 試験の日時を予約する。
  Reserve the examination date and time.

Mistake 3: Assuming 申し込み Means Acceptance

申し込み does not necessarily mean that your participation or use of a service has been approved.

For example:

• イベントに申し込む
  Apply for the event.

• 抽選結果を待つ
  Wait for the lottery results.

• 当選したら参加が決まる
  Your participation is confirmed if you are selected.

A reservation, on the other hand, usually indicates that a seat, room, or time has been secured.

Still, depending on the business, a reservation request may require final confirmation. Always check whether the reservation has been officially confirmed.

How to Choose the Correct Answer on the JLPT

In JLPT vocabulary and reading questions, look carefully at what the person is trying to secure or request.

Choose 予約 When You See Seats, Rooms, or Times

The following words often appear with 予約:

• 席: seat
• 部屋: room
• 座席: passenger seat
• 時間: time
• 診察: medical consultation
• 面談: interview or consultation
• 宿泊: accommodation
• レストラン: restaurant
• 美容院: hair salon

Example:

週末は混雑するので、ホテルを早めに（　　　）ほうがいい。
Hotels are crowded on weekends, so it is better to ______ one early.

The speaker wants to secure a hotel room. Therefore, the correct answer is:

予約した
reserved

Choose 申し込み When You See Participation or Registration

The following words often appear with 申し込み:

• 参加: participation
• 受験: taking an examination
• 受講: taking a course
• 入会: joining an organization
• 利用: use of a service
• 契約: contract
• 登録: registration
• 応募: application or entry
• 手続き: procedure

Example:

日本語スピーチ大会に参加する人は、今月末までに（　　　）ください。
Anyone participating in the Japanese speech contest should ______ by the end of this month.

The sentence describes a registration procedure for participating in the contest. Therefore, the correct answer is:

申し込んで
apply or register

Pay Attention to Particles

予約する often takes the particle を because the speaker is securing a particular object, place, or service.

• ホテルを予約する
  Reserve a hotel.

• レストランを予約する
  Reserve a restaurant table.

• 診察を予約する
  Make a medical appointment.

申し込む often takes the particle に when referring to the event, course, or examination the person wishes to join.

• 試験に申し込む
  Register for an examination.

• 講座に申し込む
  Enroll in a course.

• イベントに申し込む
  Register for an event.

However, を is also possible in expressions such as:

• サービスを申し込む
  Apply for a service.

• 参加を申し込む
  Request to participate.

Do not choose your answer based only on the particle. Always check the meaning of the entire sentence.

A Simple Decision Rule

When you are unsure, ask yourself these questions:

• Am I securing a seat, room, product, or time? Choose 予約.
• Am I officially expressing my wish to participate or use something? Choose 申し込み.
• Is a specific date, place, or time being fixed? 予約 is likely.
• Is there an application form, registration procedure, or approval process? 申し込み is likely.

In other words:

予約 = securing something
申し込み = requesting participation or use

Summary

予約 (yoyaku) and 申し込み (mōshikomi) both describe actions taken in advance, but they have different purposes.

• 予約 means securing a seat, room, time, product, or service.
• 申し込み means officially requesting to participate in an activity or use a service.
• Use 予約 for restaurants, hotels, hospitals, salons, seats, and appointments.
• Use 申し込み for examinations, courses, events, memberships, and services.
• Some situations require both: first you apply, and then you reserve a specific time.

Understanding distinctions like this will help you choose more natural expressions in conversations, business situations, and JLPT questions.
