Hello, I’m Kodak.
You enter a shop in Japan, and several staff members suddenly call out:
Irasshaimase!
A small nod, a smile, or simply continuing inside is completely natural.
いらっしゃいませ (irasshaimase) is the standard greeting used by staff to welcome customers into a shop, restaurant, hotel, or other service setting.
It is commonly translated as “Welcome!” or “Please come in!”
Customers are not expected to reply. A nod or smile is enough.
In this article, you will learn:
② whether you should respond—and what you can say
③ how to pronounce いらっしゃいませ naturally
④ why Japanese staff say it even after you are already inside
⑤ how the expression developed
⑥ the differences between いらっしゃいませ, いらっしゃい, and ようこそ
⑦ useful example dialogues for shops, restaurants, and hotels
What Does Irasshaimase Mean in Japanese?
Romaji: irasshaimase
Common English translations:
・Welcome!
・Please come in!
・Hello, and welcome.
・May I help you? (depending on the service context)
いらっしゃいませ is a polite customer-service greeting. Staff say it to acknowledge and welcome a person who has entered as a customer.
It does not always match one fixed English sentence. In a department store, it may feel like “Welcome.” In a restaurant, it may function more like “Hello—please come in.” In a shop, it can also carry the feeling of “We have noticed you and are ready to help.”
Today, however, most speakers use it as a fixed customer-service greeting without thinking about the literal grammar.
How Should You Respond to Irasshaimase?
The most important answer is simple:
Natural responses include:
・a small nod
・a smile
・brief eye contact
・quietly continuing into the shop
・answering the staff’s next question
The greeting is part of the staff’s role. A customer who quietly enters is behaving normally.
The Safest Response: A Nod or Smile
If you make eye contact with the staff, a small nod or smile is polite and natural. You do not need to bow deeply or stop walking.
Irasshaimase.
Welcome.
Customer: [smiles or nods]
No spoken reply is necessary.
Can You Say Konnichiwa?
Yes. こんにちは (konnichiwa) is possible, especially in a small shop where the owner greets you directly and the interaction feels personal.
In a large convenience store, supermarket, or department store, however, replying to every いらっしゃいませ with こんにちは may feel unnecessary.
Should You Say Arigatou Gozaimasu?
You can thank the staff later when they help you, hand you an item, or complete the transaction. However, ありがとうございます is not required as an immediate reply to the entrance greeting.
いらっしゃいませ。
⇒ A nod or smile is enough.
After receiving help:
ありがとうございます。
Arigatō gozaimasu.
Thank you very much.
After eating at a restaurant:
ごちそうさまでした。
Gochisōsama deshita.
Thank you for the meal.
At a Restaurant, Respond to the Next Question
Restaurant staff often say いらっしゃいませ and immediately ask how many people are in your group.
Irasshaimase. Nanmei-sama desu ka?
Welcome. How many people?
Customer: 二人です。
Futari desu.
Two people.
一人です — One person.
二人です — Two people.
三人です — Three people.
予約しています — I have a reservation.
How to Pronounce Irasshaimase
Romaji: irasshaimase
Mora breakdown: い・ら・っ・しゃ・い・ま・せ
Number of morae: 7
A beginner-friendly rhythm is:
The spelling can look intimidating, but the phrase becomes easier when you focus on four points.
1. Do Not Pronounce the Small っ as “Tsu”
The small っ does not have its own “tsu” sound. It creates a short hold before しゃ (sha).
i-ra-tsu-sha-i-ma-se
Better image:
i-ra-[brief hold]-sha-i-ma-se
That short beat is important because っ counts as one mora in Japanese rhythm.
2. しゃ Is One Unit: “Sha”
The characters し + small ゃ combine to make しゃ (sha). Do not pronounce them separately as shi-ya.
Not: shi-ya
3. The Japanese R Is a Quick Tap
The ら (ra) sound is made with a quick tongue tap. It is not exactly the English r or l. For a beginner, a light sound between them is close enough.
4. Pronounce Both Vowels in しゃい
しゃい contains しゃ + い. Keep the rhythm moving through both parts instead of swallowing the い.
i ・ ra ・ hold ・ sha ・ i ・ ma ・ se
You may hear the final せ extended, but the basic word is still いらっしゃいませ.
Common Romanization and Spelling Mistakes
Common search spelling: irashaimase
Japanese: いらっしゃいませ
The double ss in irasshaimase represents the small っ. Writing irashaimase is common online, but it does not show the held consonant clearly.
How Is Irasshaimase Written in Japanese?
Katakana for stylistic emphasis: イラッシャイマセ
Romaji: irasshaimase
In normal modern Japanese, the expression is usually written entirely in hiragana. Katakana may appear on signs, advertisements, manga, or designs, but it is not the standard everyday spelling.
For learners, there is no practical reason to force it into kanji.
The Grammar and Origin of Irasshaimase
いらっしゃいませ can be divided into two main parts:
A form derived from the honorific verb いらっしゃる
ませ
The imperative form of the polite auxiliary ます, used here as a polite invitation or encouragement
What Does いらっしゃる Mean?
いらっしゃる (irassharu) is an honorific verb that can mean:
・to go
・to be / to exist
The exact English meaning depends on context.
先生がいらっしゃいました。
Sensei ga irasshaimashita.
The teacher came.
社長はいらっしゃいますか？
Shachō wa irasshaimasu ka?
Is the company president here?
How いらっしゃる Becomes いらっしゃい
The continuative form いらっしゃり underwent a sound change called イ音便 (i-onbin), producing いらっしゃい.
↓
いらっしゃり
↓ sound change
いらっしゃい
What Does ませ Mean?
ませ is the imperative form of the polite auxiliary ます. Here, it does not sound like a harsh command. It politely invites or encourages the customer to come in.
↓
a polite invitation to come
↓
a conventional greeting welcoming a customer
Translating it simply as “Come here!” would sound much more commanding in English than the Japanese expression feels.
Why Do Staff Say Irasshaimase After You Are Already Inside?
This question becomes confusing when you only look at the original grammar:
Today, it also communicates: “We noticed that you arrived as a customer.”
The National Institute for Japanese Language and Linguistics explains that the phrase was used in the Edo period to call potential customers toward attractions and businesses. Through repeated use, it became established as a broad expression of welcome.
In a modern store, いらっしゃいませ can reassure you that:
・they recognize you as a customer
・someone will assist you when available
・you are welcome to browse or wait
This is why a staff member may call いらっしゃいませ from another part of the restaurant even before coming to your table.
How Old Is the Expression Irasshaimase?
Dictionary records include an example of いらっしゃいませ from around 1779 in an Edo-period work. This does not prove that nobody used it earlier, but it shows that the expression was already documented in the eighteenth century.
A polite expression encouraging someone to approach or enter
↓
Used in customer solicitation and welcoming
↓
Repeated as a conventional greeting
↓
Modern customer-service expression: いらっしゃいませ

Can a Customer Say Irasshaimase?
Normally, no. いらっしゃいませ is tied to the role of the person welcoming and serving the customer.
It could be understood as a joke, but it is not the normal customer response.
The expression is strongly associated with the social roles of staff and customer. A worker says it while acting as a representative of the shop or service.
Why Is Irasshaimase Sometimes Shouted?
In some Japanese stores and restaurants, staff use a loud, energetic voice. Several employees may repeat the greeting after one person says it.
This style can:
・create an energetic atmosphere
・signal attentiveness
・help staff members notice new customers
・follow the shop’s service routine
Irasshaimase in Anime, Games, and Japanese Restaurants Abroad
In anime and games, you may hear いらっしゃいませ whenever a character works in a café, restaurant, convenience store, inn, or maid café.
Irasshaimase! Kochira e dōzo.
Welcome! This way, please.
いらっしゃいませ、ご主人様。
Irasshaimase, goshujin-sama.
Welcome, Master.
A stylized maid-café expression rather than ordinary customer service.
Japanese restaurants outside Japan also sometimes use the phrase to create a Japanese atmosphere. The basic meaning remains the same.
For normal pronunciation practice, focus on the seven-mora rhythm and the small っ.

Common Beginner Mistakes
Mistake 1: Saying Irasshaimase Back to the Staff
This reverses the customer and staff roles. Use a nod, smile, or optional こんにちは instead.
Mistake 2: Pronouncing the Small っ as Tsu
Natural rhythm: i-ra-[hold]-sha-i-ma-se
Mistake 3: Dropping One S in Romaji and Pronunciation
The spelling irasshaimase helps show that the consonant before sha is held briefly.
Mistake 4: Treating It Like a Question
いらっしゃいませ does not ask what you want. Wait for an actual question such as 何名様ですか or 何かお探しですか.
Mistake 5: Using It as a General “Welcome to Japan”
For a destination or event, ようこそ is often more suitable.
Welcome to Japan.
お店に入る客へ：いらっしゃいませ。
To a customer entering a shop: Welcome.
