People from other countries sometimes ask me, “Why do Japanese people say ‘sumimasen’ so often?” It’s a fair question. In everyday life here, you’ll hear it constantly — when someone lets you go first, when a stranger helps you with something, when you call a waiter over, when you simply need to ask someone for directions.
Sumimasen is usually translated as “I’m sorry,” so it’s easy to assume that Japanese people are apologizing all the time. But in my experience, that’s not quite what’s happening. Often, the word slips out almost automatically, without any real sense of guilt behind it. I say it constantly myself, and I don’t think I’m sorry nearly as often as it might sound.
In this article, I’ll walk through the situations where sumimasen comes up, why it doesn’t always mean an apology, and something I’ve personally been rethinking about how I use it.
“Sumimasen” Does Not Always Mean “I’m Sorry”
When you first learn Japanese, sumimasen is usually introduced as “I’m sorry” — the equivalent of gomen nasai. And yes, it is used that way. If you’re late, if you’ve caused trouble, if you’ve made a mistake, you’ll hear things like “okurete sumimasen” (sorry for being late).
But in daily conversation, that’s only part of the story. Depending on the situation, sumimasen can carry apology, gratitude, consideration for the other person, a soft request, a way of getting someone’s attention, or a bit of quiet awkwardness about having put someone out.
That’s exactly why it resists a single, clean English translation.
When Do Japanese People Say “Sumimasen”?
Picture a narrow street or a crowded shop aisle. Someone steps aside so you can pass, and you say, “Ah, sumimasen.” This isn’t an admission that they did something wrong by making room for you. It’s closer to “Thank you for thinking of me,” mixed with a little bit of “I’m sorry to have caused you the trouble of moving.”
If someone picks up something you dropped, or carries a bag for you, you might say, “Sumimasen. Arigatou gozaimasu” — literally, “I’m sorry. Thank you.” Said aloud in English, that combination sounds strange. But to many Japanese ears, it doesn’t feel odd at all, because both feelings — gratitude for the help, and a slight sense of having inconvenienced someone — tend to arrive together.
The same thing happens on trains and buses. If someone offers you their seat and says, “Douzo” (please, go ahead), a common reply is “Sumimasen. Arigatou gozaimasu.” A visitor might wonder, “Why are you apologizing?” But it’s rarely really an apology — it’s gratitude layered with a bit of modesty about being the reason someone gave up their seat.
In a restaurant, you’ll hear people call out “Sumimasen!” to get a server’s attention. No apology is intended here at all — it functions almost exactly like “Excuse me!” in English.
Sumimasen also opens requests: “Sumimasen, could you show me this?” “Sumimasen, could you take a photo for me?” “Sumimasen, where’s the station?” In Japanese, leading with sumimasen softens the request. Asking “Please take a photo” outright can sound abrupt, while starting with sumimasen works almost like a cushion, making the exchange feel gentler.
You’ll also hear it when someone needs to pass in front of you — getting off a train, or squeezing by in a tight space. It’s not a heavy admission of wrongdoing so much as a quick “Excuse me, coming through,” paired with an acknowledgment that you’re briefly stepping into someone else’s space.
Why Can “Sumimasen” Mean “Thank You”?
One of the more interesting quirks of sumimasen is that it can express genuine gratitude. If someone gives you a gift, you might hear, “Oh, sumimasen!” — and no, that doesn’t mean “I’m sorry you gave me a gift.”
What’s usually happening is a blend of “Thank you for thinking of me” and a touch of “I feel bad that you went to the trouble.” In this sense, sumimasen can express appreciation for someone’s kindness while also acknowledging the effort it took them.
“Sumimasen” and “Arigatou” Are Not Quite the Same
Both sumimasen and arigatou can express thanks, but they’re not interchangeable. Arigatou is a direct, unclouded expression of gratitude for what someone did. Sumimasen, on the other hand, often carries an added layer — something closer to “I’m grateful, and I also feel a little sorry for the trouble I caused.”
If someone helps you and you say “arigatou,” it reads as straightforward thanks. Say “sumimasen” instead, and it can carry the sense of “Thank you for helping me — and I’m sorry for the bother.” Of course, how strongly that second layer comes through depends on the person and the moment. Still, understanding this distinction makes it a little easier to see why someone might reach for “sumimasen” instead of “arigatou.”
Why I Try to Say “Arigatou” More Often
Lately, I’ve been trying to say “arigatou” more often than “sumimasen.” This is a personal choice, but I also sense a broader shift in how some people here think about it — the idea that saying a plain “thank you” can be better than instinctively apologizing.
Sumimasen is practically a verbal habit for me, so it used to come out reflexively even when someone had simply been kind to me. But I’ve started to notice that when what I actually feel is gratitude, saying “arigatou” outright tends to leave both of us feeling better. There’s something nice about being thanked plainly — it makes you glad you helped. So these days, when I want to express appreciation, I try to reach for “arigatou” first.
There’s another reason I’ve been cutting back on sumimasen: overusing it can wear down its weight. If I say it constantly over small, everyday things, I worry it loses meaning for the moments when I’ve genuinely upset someone and need it to carry real weight.
That doesn’t mean sumimasen should be avoided — when you’ve truly caused trouble or need to apologize, it’s an important word. I’ve just started pausing for a second to ask myself: is this really a moment to apologize, or is it actually a moment to say thank you? Making that small distinction, I think, lets what I actually feel come through more clearly.
“Sumimasen” or “Suimasen”?
If you listen closely to conversations here, you’ll sometimes hear “suimasen” instead of “sumimasen.” Suimasen is a casual contraction that shows up naturally in spoken Japanese.
Generally speaking, sumimasen reads as the more standard, slightly more polite form, while suimasen has a more relaxed, conversational feel — though this isn’t a strict rule, and suimasen isn’t limited to casual settings only.
If you’re learning Japanese, sticking with sumimasen will serve you well in nearly any situation.
Are Japanese People Really Apologizing All the Time?
So, back to the original question: are Japanese people really apologizing constantly?
Not necessarily. In moments where it might look, from the outside, like someone is saying “sorry,” they may not be apologizing at all. Sumimasen can mean “thank you,” “excuse me,” “pardon my passing through,” or “I hate to ask, but…” And sometimes, it’s simply a word that comes out on its own, without much thought behind it.
So if someone says “sumimasen” to you while you’re in Japan, you don’t need to assume every time that they’re apologizing. There’s often something more layered underneath that one small word.
A Japanese Perspective
To me, sumimasen is one of the more fascinating words for understanding how people communicate here. A single phrase can hold apology, gratitude, modesty, consideration, a request, or simply a way of getting someone’s attention — all at once.
Because it’s such a habit for me too, I’ve started paying closer attention to how I use it — asking myself whether I actually want to apologize, or whether what I really mean is thank you, and trying to choose the word that matches what I actually feel.
So the next time someone in Japan says “sumimasen” to you, you don’t have to take it as “I’m sorry.” It might be “thank you.” It might be “excuse me.” Or it might just be a word that came out naturally, without much weight behind it at all.
Noticing what’s underneath that one small word can also tell you something about how people here think about distance, consideration, and each other — which, to me, is part of what makes everyday life here so interesting to pay attention to.
