How to Say Sorry to Bother You in Japanese: Osoreirimasu and More

English uses one phrase for interrupting, entering and asking a favour. Japanese splits the job, and the right opener makes the rest of your request sound polite before you have even made it.

How to Say Sorry to Bother You in Japanese: Osoreirimasu and More

Sorry to bother you covers several situations in English: getting a stranger's attention, interrupting a busy colleague, knocking on an office door, visiting a home, calling late at night. Japanese has a phrase for each. Osoreirimasu is the polite opener for requests and questions. O-isogashii tokoro sumimasen acknowledges that the person is busy. Shitsurei shimasu is for entering a room, and ojama shimasu for entering a home. This guide sorts them, adds the written versions for emails and chat, and shows the replies you will hear.

Osoreirimasu is the polite opener before a request or question

O-isogashii tokoro sumimasen acknowledges that someone is busy

Shitsurei shimasu is for entering a room; ojama shimasu is for entering a home

Emails and chat have their own set phrases for the same idea

Why there is no single phrase

Japanese politeness often sits at the start of a request, in a cushion phrase that prepares the listener. Which cushion fits depends on what you are doing: interrupting, entering, adding work or intruding at a bad time.

Getting the cushion right matters more than the exact request wording. A plain request after a good opener sounds polite; an elaborate request without one can sound abrupt.

Osoreirimasu: the polite opener

Osoreirimasu is a humble phrase that expresses feeling awkward about troubling someone. It is the natural start to a question or request to a customer, a client or anyone you want to treat formally.

You will hear it constantly from staff, and using it yourself instantly raises the politeness of what follows.

JapaneseRomajiMeaning
恐れ入ります。Osoreirimasu.Excuse me, I'm sorry to trouble you
恐れ入りますが、少々よろしいでしょうか。Osoreirimasu ga, shōshō yoroshii deshō ka.Sorry to bother you, but do you have a moment?
恐れ入りますが、お名前をお伺いしてもよろしいでしょうか。Osoreirimasu ga, o-namae o o-ukagai shite mo yoroshii deshō ka.Excuse me, may I ask your name?
恐れ入りますが、もう一度お願いできますか。Osoreirimasu ga, mō ichido onegai dekimasu ka.I'm sorry, could you say that once more?

When someone is busy

O-isogashii tokoro sumimasen means sorry, at a time when you are busy. It acknowledges the interruption itself, which makes it the right opener with a colleague at their desk or a superior between meetings.

With peers you can shorten it to chotto ii desu ka, and with friends ima daijōbu is enough.

JapaneseRomajiMeaning
お忙しいところすみません。O-isogashii tokoro sumimasen.Sorry to bother you when you're busy
お忙しいところ申し訳ありません。O-isogashii tokoro mōshiwake arimasen.I'm very sorry to interrupt while you're busy
ちょっといいですか。Chotto ii desu ka.Got a minute?: to a colleague
今、大丈夫?Ima, daijōbu?Is now okay?: casual
お時間があるときで大丈夫です。O-jikan ga aru toki de daijōbu desu.Whenever you have time is fine

Entering a room or a home

Entering has its own phrases. At an office door, a teacher's room or a meeting room, knock and say shitsurei shimasu as you go in, and again as you leave.

At someone's home the phrase is ojama shimasu, literally I will be in your way, and ojama shimashita on the way out.

JapaneseRomajiMeaning
失礼します。Shitsurei shimasu.Excuse me: entering or leaving a room
失礼いたします。Shitsurei itashimasu.Excuse me: more formal
お邪魔します。Ojama shimasu.Sorry to intrude: entering a home
お邪魔しました。Ojama shimashita.Thank you for having me: leaving a home

Adding work or calling at a bad time

When your request creates work for someone, otesū desu ga or otesū o okake shimasu ga goes before it. When you are intruding on their time, such as a late call or a weekend message, name the time itself.

JapaneseRomajiMeaning
お手数ですが、ご確認ください。Otesū desu ga, go-kakunin kudasai.Sorry for the trouble, but please check this
ご迷惑をおかけしてすみません。Go-meiwaku o okake shite sumimasen.Sorry for the inconvenience
夜分遅くにすみません。Yabun osoku ni sumimasen.Sorry to call so late at night
お休みのところすみません。O-yasumi no tokoro sumimasen.Sorry to bother you on your day off

Emails and chat

Written Japanese has fixed cushion phrases for the same idea. They sit at the start of the request paragraph, after the opening greeting.

JapaneseRomajiMeaning
お忙しいところ恐縮ですが、O-isogashii tokoro kyōshuku desu ga,I know you are busy, but
突然のご連絡失礼いたします。Totsuzen no go-renraku shitsurei itashimasu.Please excuse this sudden message
お手数をおかけしますが、よろしくお願いいたします。Otesū o okake shimasu ga, yoroshiku onegai itashimasu.Sorry for the trouble, and thank you in advance

Making the opener a habit

The opener has to come out before you think about the request, which only happens with repetition in realistic moments. Unihongo's roleplay missions give you several: Call Work About a Train Delay starts with interrupting a busy morning, and Win Support Before the Meeting asks you to approach colleagues who have their own work.

After each conversation, the corrections in the session report can show where a request came out without a cushion, which is an error native speakers notice quickly.

  • Stranger or customer: osoreirimasu ga.
  • Busy colleague or superior: o-isogashii tokoro sumimasen.
  • Entering a room: shitsurei shimasu.
  • Entering a home: ojama shimasu.
  • Creating work: otesū desu ga.

A practical way to improve

Pick three real moments from your week, such as asking a colleague a question, calling a shop and knocking on a meeting room, and say the right opener for each aloud before the request itself. Then ask your AI Sensei in Unihongo's 3D classroom to play a busy manager, and practise opening with o-isogashii tokoro sumimasen before asking for a minute.

  1. 1

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

Is sumimasen enough to say sorry to bother you?

Often, yes. Sumimasen works to get attention and to open a small request. Osoreirimasu and o-isogashii tokoro sumimasen add politeness when the person is a customer, a superior or clearly busy.

What is the difference between shitsurei shimasu and ojama shimasu?

Shitsurei shimasu is used when entering an office, a classroom or a meeting room. Ojama shimasu is used when entering someone's home, and ojama shimashita when leaving it.

What does otesū desu ga mean?

Sorry for the trouble, but: it goes before a request that will create work for the other person, such as checking a document or filling in a form. It is common in business emails.

How do I apologise for calling late at night?

Yabun osoku ni sumimasen, or more formally yabun osoku ni shitsurei itashimasu, before stating your business.
