Welcome in Japanese: ようこそ, いらっしゃいませ — and "you''re welcome" is a different word

"Welcome" in Japanese is ようこそ when you greet someone arriving somewhere, いらっしゃいませ when you are shop staff, and どういたしまして only for "you're welcome" — English uses one word for all of these, and Japanese uses at least four.

That is why a dictionary lookup for "welcome" is so unhelpful. It hands you a list, and none of the entries tell you who is allowed to say what to whom. The good news is that the choice is nearly always decided by one question: who are you, and where are you standing?

The basics

What is the basic way to say "welcome" in Japanese?

ようこそ. It is the word for greeting someone who has just arrived at your place, your country, your event, or your group. You add the place with へ, and you get the classic pattern 〜へようこそ.

日本にほんへようこそ。 — Welcome to Japan. (the standard greeting for a visitor, on signs and in speeches) ようこそ、私わたしの家いえへ。 — Welcome to my home. (friendly, the host speaking) チームへようこそ。 — Welcome to the team. (a new colleague joins)

Notice that ようこそ is spoken by the host. A tourist does not say 日本にほんへようこそ to a local. It is one-directional: the person who "owns" the place welcomes the person who arrived.

Anime loves it. Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e (Classroom of the Elite) has ようこそ right in the title, and the Kemono Friends opening song is titled ようこそジャパリパークへ — "welcome to Japari Park." When you hear a character throw their arms open and say it, that is the whole meaning.

What do shop staff say when you walk in?

いらっしゃいませ. It is the shop-and-restaurant welcome, said by staff to customers the moment you step in.

いらっしゃいませ。 — Welcome. (shop or restaurant staff to a customer, polite) いらっしゃいませ、何名なんめい様さまですか。 — Welcome, how many people? (restaurant, the standard second line)

The single most useful fact for a learner: you do not answer it. Nobody expects a "hello" back. A small nod or eye contact is plenty, and in a busy convenience store you will hear it shouted over your shoulder from three directions while the staff keep working. It is a signal that you were noticed, not a question waiting for a reply.

The word itself is an honorific verb, いらっしゃる (to come / to be, respectful), plus the polite command ending ませ — roughly "please come in, honored guest." That is also why it belongs to the same family of customer-service language covered in でございます and service keigo.

What is the difference between いらっしゃいませ and いらっしゃい?

Drop the ませ and you get the casual, warmer version. いらっしゃい is what a host says to someone arriving at the house, and what a ramen-shop owner or izakaya cook says to customers at a small, friendly counter.

いらっしゃい!上あがって、上あがって。 — Welcome! Come on in, come in. (a host at the front door, casual) いらっしゃい!空あいてる席せきにどうぞ。 — Welcome! Sit anywhere that's free. (small ramen shop, gruff and friendly)

The reply from a guest at someone's home is not "welcome back" and not "you're welcome" — it is お邪魔じゃまします, which has its own explanation in visiting a Japanese home with おじゃまします.

What do you say to someone who comes back home?

おかえり (or the polite おかえりなさい). That is the "welcome back" of Japanese, and it is the partner of ただいま. It only works when the person really is returning to a place that is theirs — home, the office, a shared room.

おかえり! — Welcome back! (casual, family or roommate) おかえりなさい。 — Welcome back. (polite)

There is a full breakdown of the pair in ただいま and おかえり. The short version: if the person is arriving somewhere new, use ようこそ. If they are returning somewhere familiar, use おかえり.

Beyond the basics

How is "you're welcome" different?

It is a completely different English word that happens to be spelled the same. "You're welcome" as a reply to "thank you" is どういたしまして in Japanese. It has nothing to do with ようこそ.

ありがとうございます。— どういたしまして。 — Thank you. — You're welcome. (textbook exchange)

But here is the honest part that textbooks skip: real speakers use どういたしまして much less than English speakers use "you're welcome." It sounds a little formal and can even come across as slightly proud, like "yes, I did you a favor." Most people reply with something lighter:

いえいえ。 — Oh, no, no. (casual, the most common reply) とんでもないです。 — Not at all. (polite, humble) 大丈夫だいじょうぶですよ。 — It's fine. (friendly, everyday)

Use どういたしまして when you are practicing, or when someone thanks you very formally. Use いえいえ when you want to sound like a person. If the thank-you side of the exchange is shaky, how to say thank you in Japanese covers the other half.

What about "you're welcome to..." or "welcome in"?

Japanese uses どうぞ instead. When English says "you're welcome to take one" or "welcome, come in," the Japanese speaker offers with どうぞ and a gesture.

どうぞ、お入はいりください。 — Please, come in. (polite, holding the door) ご自由じゆうにどうぞ。 — Help yourself. (free samples, brochures on a table)

You do not need a "welcome" word at all. どうぞ carries the whole invitation.

How do you welcome someone to a group, and what is a welcome party?

Two words: 歓迎かんげいする (to welcome, to receive warmly) and 歓迎会かんげいかい (a welcome party). These are the heavier, organized kind of welcome.

新入社員しんにゅうしゃいんを歓迎かんげいします。 — We welcome the new employees. (formal, written or spoken at an event) 来週らいしゅう、新人しんじんの歓迎会かんげいかいがあります。 — Next week there is a welcome party for the newcomers. (everyday, workplace or club)

歓迎会かんげいかい is a real institution in Japanese workplaces and clubs: a dinner or drinks, usually at an izakaya, held when someone joins. If you start a new job or club, expect one. The typical line from the newcomer is まだ慣なれていませんが、よろしくお願ねがいします — a modest "I'm still new, please look after me," not a big speech.

What does "welcome" map to, at a glance?

English "welcome" Japanese Who says it
Welcome to (a place) 〜へようこそ The host, to a new arrival
Welcome (shop, polite) いらっしゃいませ Staff to a customer
Welcome (casual, at home or small shop) いらっしゃい Host, owner, cook
Welcome back おかえり / おかえりなさい Someone at home, to a person returning
You're welcome (reply to thanks) どういたしまして / いえいえ The person who was thanked
You're welcome to... / help yourself どうぞ Anyone offering
Welcome someone to a group 歓迎かんげいする / 歓迎会かんげいかい The group or company

Common mistakes

  • Saying ようこそ when you are the visitor. It is the host's word. Tell the host お邪魔じゃまします, or at a shop just nod.
  • Answering いらっしゃいませ with "hello" or "thank you." You can, and nothing bad happens, but it is not expected. A nod is the natural response.
  • Using どういたしまして every single time someone thanks you. Correct, but stiff. いえいえ and 大丈夫だいじょうぶですよ are what you actually hear.
  • Using ようこそ for someone coming home. A family member returning is おかえり. ようこそ would sound like you are treating them as a guest in their own house.
  • Using いらっしゃいませ as a greeting to friends. It is customer-service language and only fits the person behind the counter. A friend at the door gets いらっしゃい.

Practice

Build each answer before opening it. Questions 5 and 6 are a pair — same English word, different Japanese.

1. You run a small guesthouse, and a guest walks in. Say "Welcome to Japan."

Show answer

日本にほんへようこそ — ようこそ is the host's welcome, and へ marks the place.

2. You work at a store, and a customer enters. What do you say?

Show answer

いらっしゃいませ — the polite customer-service welcome, said by staff, and the customer does not have to reply.

3. A ramen-shop owner greets you with a gruff, friendly welcome. Which form is it?

Show answer

いらっしゃい — the casual form without ませ, the warmer one for small shops and homes.

4. A roommate walks in after work. Which do you say: ようこそ or おかえり?

Show answer

おかえり — they are returning to a place that is theirs. ようこそ would treat them as a first-time guest.

5. A friend says ありがとう. Give a polite textbook reply meaning "You're welcome."

Show answer

どういたしまして — the standard "you're welcome," a separate word from ようこそ.

6. Same situation, but you want to sound like a native speaker in daily life. What is a lighter reply?

Show answer

いえいえ — or 大丈夫だいじょうぶですよ. どういたしまして is correct but sounds formal, so people usually choose these.

7. You are the visitor at a friend's front door and the host says いらっしゃい. What do you say back?

Show answer

お邪魔じゃまします — the guest's line when entering someone's home. You do not answer a welcome with a welcome.

8. You want to say "help yourself" over a plate of free samples.

Show answer

ご自由じゆうにどうぞ — どうぞ carries the offer, so no "welcome" word is needed.

9. What is a 歓迎会かんげいかい?

Show answer

A welcome party for a new member of a company or club, typically a dinner or drinks.

10. Why is a tourist saying 日本にほんへようこそ to a local a mistake?

Show answer

ようこそ belongs to the host. The person who owns the place welcomes the person who arrived, never the other way around.

A trial lesson is a good place to greet a guest with ようこそ, play shop staff with いらっしゃいませ, and answer a thank-you with どういたしまして.

FAQ

Do I have to say something back when a shop says いらっしゃいませ? No. A nod or a quick glance is enough, and most customers say nothing at all.

Is いらっしゃいませ the same as ようこそ? They overlap in meaning, but they are used in different places. いらっしゃいませ is for shop and restaurant staff greeting customers. ようこそ is for a host greeting a guest at a place or event, and usually names the place: 〜へようこそ.

Is どういたしまして rude? It is not rude, but it can sound a bit stiff or self-important in casual talk. いえいえ is the everyday reply.

Can I say おかえり to a guest? Only if they have effectively become part of the household. A first-time visitor gets いらっしゃい or ようこそ; someone who lives there gets おかえり.

What do I say to welcome someone to a party? いらっしゃい is natural for a casual party at your home, and ようこそ works if you want a warmer, slightly more formal announcement.

I've taught on italki as a Top 1% teacher and watched over 1,500 anime, so most of the example sentences on this blog come from lines I've actually heard students ask about — including this one, since learners are often surprised that "welcome" is really four different words.
