Sorry in Japanese: Gomen, Sumimasen and How to Apologize Properly

How to say sorry in Japanese

The short answer to how to say sorry in Japanese is that it depends on who you are talking to and how serious the situation is. There is a casual layer for friends and family, a polite everyday layer for strangers and coworkers, and a formal layer for the workplace, customers, and real mistakes. Pick the wrong layer and you will not cause a disaster, but you will sound slightly off, either too stiff with a friend or far too casual with your boss.

Here is the map in one glance. With people you are close to, you say ごめん (gomen) or the slightly fuller ごめんなさい (gomen nasai). In ordinary polite situations, and any time you would say excuse me in English, you reach for すみません (sumimasen). When something is genuinely your fault in a formal setting, you use 申し訳ありません (moushiwake arimasen), which carries real weight. And there is a small family of set phrases like 失礼します (shitsurei shimasu) that handle specific moments, such as leaving a room or squeezing past someone.

If you only remember one word from this whole guide, make it sumimasen. It is the most useful apology word in the language because it does double duty as sorry and as excuse me, and it sits at a polite level that almost never sounds wrong with strangers. A traveler who knows nothing but sumimasen can bump into someone, call a waiter, ask a question, and thank a stranger for their trouble, all with the same word. Everything else in this guide adds precision on top of that foundation.

One more thing to understand before the details: in Japanese, apologizing is not only about admitting fault. A light sumimasen often works as social glue, a way of acknowledging that you have taken a moment of someone's time or attention. That is why you will hear apology words far more often than you would hear sorry in an English conversation. Keeping that in mind will stop the frequent apologizing from feeling strange and help you use it the way native speakers do.

Gomen and gomen nasai, the casual apology

ごめんなさい (gomen nasai) is the direct, personal way to say I am sorry, and its shorter form ごめん (gomen) is the casual version you use with people you are close to. Where sumimasen is polite and a little neutral, gomen nasai is warmer and more heartfelt. It is the phrase you say to a friend, a partner, a sibling, or a parent when you have done something wrong and you mean it.

The two forms differ mainly in politeness. ごめん (gomen) on its own is short and casual, the equivalent of a quick sorry between friends. Adding なさい (nasai) makes it more complete and a touch more polite, closer to I am sorry said properly. You can also soften gomen with the particle ね (ne) to make ごめんね (gomen ne), which sounds gentle and friendly, the kind of thing you say for a small slip like being a few minutes late to meet a friend.

The important limit to remember is that gomen and gomen nasai are casual. They belong with people you know well, and they can sound too familiar or even a little childish if you use them with a stranger, a customer, or your manager. A child saying gomen nasai to a parent is perfectly natural. An employee saying gomen nasai to a client for a serious error would sound out of place, because the situation calls for the heavier, more formal apology we cover later. Match the phrase to the relationship, not just the size of the mistake.

To make gomen stronger among friends, you can put an intensifier in front of it. 本当にごめん (hontou ni gomen) means I am really sorry and carries more feeling, good for when you have genuinely let a friend down rather than just bumped their elbow. The pattern is the same one you use across the language: keep the core word, and add a word like hontou ni, meaning really or truly, to raise the intensity.

Sumimasen, the everyday workhorse

すみません (sumimasen) is the single most useful word in this guide, because it stretches across three jobs at once: sorry, excuse me, and even a soft thank you for someone's trouble. It sits at a polite, neutral level that works with strangers, shop staff, coworkers, and most people you do not know well, which is exactly the range where new learners feel least sure of themselves. Learn to say it comfortably and you have covered the bulk of everyday situations.

As an apology, sumimasen handles small to medium slips politely. You step on someone's foot on a crowded train, you say sumimasen. You are a little late to a meeting with someone you are not close to, sumimasen. It admits a minor fault and shows courtesy without the heavy weight of a formal apology, which would sound like overkill for something small.

As excuse me, sumimasen is how you get attention or make your way through. In a restaurant, sumimasen is the normal way to call a server over, and here it means nothing more than excuse me, over here. In a crowd, you say it to ask people to let you pass. To stop a stranger and ask directions, you open with sumimasen to politely get their attention before your question. In all of these, no real apology is involved, just a polite acknowledgment that you are interrupting or taking a moment of their time.

Sumimasen also has a past form, すみませんでした (sumimasen deshita), which you use to apologize for something you already did. If you were late and are now apologizing after the fact, sumimasen deshita fits, because the deshita marks it as past. This small change matters: sumimasen is for the moment or for something ongoing, while sumimasen deshita closes the book on something that has already happened.

Because sumimasen covers so much, it is worth practicing until it comes out without thinking. It is the apology equivalent of a swiss army knife, and travelers in particular can get remarkably far on it alone. If you are still building your base of everyday phrases, our guide to Japanese greetings pairs naturally with this one, since greetings and sumimasen together cover most of the small polite exchanges of a normal day.

Moushiwake arimasen, the formal apology

When an apology has to carry real weight, Japanese moves up to 申し訳ありません (moushiwake arimasen). This is the phrase for the workplace, for customers, and for genuine mistakes that a casual gomen or a light sumimasen could not cover. It is noticeably more formal, and it signals that you are taking the situation seriously.

The literal meaning explains the force of it. The core word 申し訳 (moushiwake) means excuse or justification, so the whole phrase says, in effect, there is no excuse. You are not just saying sorry, you are stating that nothing can justify what happened, which is a much stronger and more humble stance than a simple apology. That is why it lands as sincere and serious in the settings where it belongs.

There is an even more formal version, 申し訳ございません (moushiwake gozaimasen), which swaps in the humble verb gozaimasen for arimasen. This is the register of customer service, official announcements, and formal business apologies. If you hear a station attendant apologize for a delayed train or a shop clerk apologize for a problem, this is very often the phrase they use. As a learner you may not need to produce it often, but you should recognize it, because it is everywhere in public and professional Japanese.

To make a formal apology fuller, speakers often add a phrase describing what they are sorry for, or precede it with a word like 本当に (hontou ni), meaning truly. Something like hontou ni moushiwake arimasen deshita, truly, there was no excuse for what happened, is a complete and heartfelt formal apology for a past mistake. The deshita again marks it as past, closing off something that has already occurred. In formal settings, this kind of apology is almost always paired with a bow, which we come to shortly.

Shitsurei shimasu and other set phrases

Beyond the three main apologies, Japanese has a handful of set phrases that handle specific polite moments, and the most useful is 失礼します (shitsurei shimasu). The core word 失礼 (shitsurei) means rudeness or discourtesy, so the phrase literally says I am about to be rude, and it works as a polite excuse me for a specific act rather than a general apology.

You use shitsurei shimasu at the moment of a small, unavoidable imposition. Entering someone's office or a meeting room, you say it as you step in, acknowledging that you are intruding on their space. Leaving before others, especially at work, you say it on your way out, meaning excuse me for leaving. Squeezing past someone in a tight space, hanging up a phone call, or reaching across someone at a table can all be softened with shitsurei shimasu. It is the polite marker for those little intrusions that dot a normal day.

Like sumimasen, it has a past form, 失礼しました (shitsurei shimashita), which you say after the fact for a small rudeness you have already committed. If you bumped a colleague, gave a wrong answer, or interrupted at the wrong moment, shitsurei shimashita apologizes for that specific slip in a polite, businesslike way. The pattern mirrors sumimasen and sumimasen deshita: the plain form for the moment, the past form for something done.

Two more useful set expressions round this out. お詫び申し上げます is very formal and beyond most learners, but the noun お詫び (owabi), meaning apology, is worth recognizing because you will see it in formal written apologies and public notices. And the verb 謝る (ayamaru), meaning to apologize, is the word you use to talk about apologizing itself, as in I need to apologize, rather than a phrase you say to someone directly. Knowing these helps you understand apologies you read and hear, even the ones you would not produce yourself.

Casual expressions and quick sorries

Among close friends, Japanese has even lighter ways to say sorry that fall below gomen, and they are worth knowing so casual speech does not throw you. The most common is 悪い (warui), literally bad, used the way English speakers say my bad. You can soften it to 悪いね (warui ne), which lands as sorry about that or my bad, said lightly to a friend for a small thing like forgetting to reply to a message.

These casual forms carry a clear warning label: they are only for friends and people your own age or younger that you are relaxed with. Warui to a stranger, a customer, or anyone senior would sound rude and far too blunt, because it drops all the politeness that sumimasen carries. Think of it the way you would think about saying my bad in English. Fine with a friend, wrong in a job interview.

You will also hear gomen shortened and stretched in casual speech, with fillers and particles that soften or intensify it. ごめんね (gomen ne) is gentle and friendly. Repeating it, as in gomen gomen, sounds like a quick, light sorry sorry when you have made a small slip and want to smooth it over without much fuss. None of these belong in formal situations, but they are a big part of how friends actually talk, so recognizing them will make casual conversation feel far less confusing.

A good rule for the casual layer: use it only after you have a feel for the relationship. When you are unsure how close you are with someone, default up to sumimasen, which is polite enough to be safe and casual enough not to sound cold. As you get more comfortable and hear how the people around you speak, the lighter forms will start to feel natural in the right company. If you want more of this everyday vocabulary, our roundup of common Japanese words is a good next stop.

The culture of apology and bowing

To use these phrases well, it helps to understand that apologizing in Japan carries a different social weight than in many Western cultures. Apologizing first is widely seen as considerate and mature, a sign that you are aware of the people around you and willing to take responsibility for smoothing a situation. It is not necessarily an admission of deep guilt. Often it is a small social courtesy, a way of oiling the gears of an interaction.

This is why a light sumimasen shows up so often, and why it can mean thank you for your trouble as much as it means sorry. If someone holds a door, picks up something you dropped, or goes out of their way for you, a sumimasen acknowledges the effort they spent on your behalf. In English you would say thank you; in Japanese, an apology-shaped phrase does the same warm work, because it centers the other person's trouble rather than your own gratitude. Once you see this, the constant apologizing stops feeling odd and starts to look like ordinary politeness.

The bow is the physical half of an apology, and the two go together. For a light, everyday sumimasen, a small nod of the head is enough, the kind you barely think about. For a sincere apology to a friend or a polite one to a coworker, a fuller bow from the waist, held for a moment, matches the words. For a serious, formal apology, the bow goes deeper and is held longer, and the deeper and longer it is, the more remorse it signals. A formal moushiwake arimasen without any bow at all would feel incomplete to a Japanese listener, like the words are missing their body.

You do not need to master the exact angles as a learner, and no one expects a foreigner to bow perfectly. What matters is knowing that the bow exists and roughly scaling it: a nod for small things, a proper bend for serious ones. Even a modest bow paired with the right words reads as respectful and sincere, and it shows you understand that in Japanese, an apology is something you do with your whole body, not just your mouth. This layer of culture is one of the things that makes the language rewarding to learn; our guide on how to learn Japanese goes further into fitting the language and its customs together.

Casual vs formal: which to use when

The whole system becomes easy once you stop thinking about the size of the mistake and start thinking about two things together: who you are talking to, and how serious the situation is. Those two dials, relationship and seriousness, decide which phrase fits. A small mistake with a friend and a small mistake with a customer call for completely different words, even though the mistake is the same.

Start with the relationship, because it sets the floor. With close friends and family, you can use the casual layer, gomen and even warui. With strangers, shop staff, and coworkers you are not close to, you default to the polite layer, sumimasen. With customers, senior figures, and anyone in a formal role, you move to the formal layer, moushiwake arimasen. If you get only this part right and ignore everything else, you will already sound appropriate most of the time.

Then adjust for seriousness within that relationship. Among friends, a tiny slip gets a light gomen ne, while genuinely letting someone down gets a heartfelt hontou ni gomen. At work, a minor interruption gets shitsurei shimasu, while a real error that affected someone gets moushiwake arimasen with a proper bow. The relationship picks the layer, and the seriousness picks how strong a phrase you use within it.

When the two dials point in different directions, let the relationship win and lean polite. If you are unsure whether you are close enough with someone to use gomen, use sumimasen instead, because being slightly too polite almost never causes a problem, while being too casual can. This safe-default habit is the same one that serves you across all of spoken Japanese, and it takes the pressure off having to judge every situation perfectly in the moment.

How to reply when someone apologizes

Knowing how to accept an apology is just as important as knowing how to give one, and the replies are short and easy to learn. The most useful is 大丈夫です (daijoubu desu), meaning it is okay or I am fine, which reassures the other person that no harm was done. Among friends you can drop the desu and just say 大丈夫 (daijoubu), which lands as it is fine, no worries.

Another warm, common reply is 気にしないで (ki ni shinaide), meaning do not worry about it or never mind. It gently tells the person to let it go, and it pairs well with daijoubu, as in daijoubu, ki ni shinaide, it is okay, do not worry about it. In a more polite setting you can lengthen it to ki ni shinaide kudasai, please do not worry about it, which softens it for someone being formal with you.

To wave off a light apology, especially the sumimasen that really means thank you for your trouble, you can simply say いいえ (iie), meaning no or not at all. It plays the role of the English no worries or not at all, brushing aside the need for any apology. Said with a small smile or a little wave of the hand, iie is a graceful way to tell someone there was nothing to be sorry for in the first place.

As always, match your reply to the level of the apology. A friend who says gomen ne gets a relaxed daijoubu. A coworker who offers a polite sumimasen gets an iie or a daijoubu desu. Someone giving a formal apology deserves a softer, more careful reply, and in many formal situations the graceful move is to accept warmly and downplay the fault rather than dwell on it. Getting the reply right shows the same social awareness that choosing the right apology does, and native speakers notice it.

Worked examples for real situations

Rules are easier to trust once you see them play out, so here are common situations with the phrase that fits each one and why. Read the Japanese aloud as you go, because saying these is what moves them from something you understand into something you can actually produce.

You step on someone's foot on the train. Say すみません (sumimasen) with a small nod. It is a stranger and a minor accident, so the polite everyday apology is exactly right, and gomen would be too casual with someone you do not know.

You are ten minutes late to meet a close friend. Say ごめんね (gomen ne) or, if you feel bad about it, 本当にごめん (hontou ni gomen). The casual layer fits a friend, and the intensifier scales it to how sorry you feel.

You want to call a server in a restaurant. Say すみません (sumimasen), maybe with a slightly raised hand. Here it is not an apology at all but a polite excuse me to get attention, and it is the standard way to do it.

You are entering your manager's office. Say 失礼します (shitsurei shimasu) as you step in. It politely marks that you are intruding on their space, which is the exact job this phrase does.

You made a mistake at work that affected a client. Say 申し訳ありません (moushiwake arimasen) with a proper bow, or in past form for something already done. The setting is formal and the fault is real, so only the heavy apology fits.

A friend apologizes for forgetting to bring something. Reply 大丈夫 (daijoubu) or 気にしないで (ki ni shinaide). You are reassuring a friend, so the warm, casual reply is the natural one.

A stranger says sumimasen while letting you pass. Reply いいえ (iie) with a small nod. Their sumimasen is really a thank you for your trouble, so you wave it off with a graceful not at all.

Notice how the same accident can call for different words depending on who is involved, and how the same word, sumimasen, does apology and excuse me work in different moments. That flexibility is the whole reason it is worth over-practicing sumimasen first, then adding the casual and formal layers around it as your ear for situations improves. If you want a broader base of everyday Japanese to slot these into, the Japanese alphabet guide and our piece on how long it takes to learn Japanese both help you see where phrases like these fit in the larger picture.

Quick reference table

Here is everything in one place. Keep this handy while the phrases are still new, and lean on the last column, which tells you the level and the moment each phrase belongs to.

A final note on the table: the phrases in the middle rows, sumimasen and its relatives, are the ones to drill first, because they cover the widest range of situations. The casual forms at the top and the formal forms in the center are refinements you add as you get a feel for who you are speaking with. Practice the everyday layer until it is automatic, and the rest slots in around it. For counting, times, and the other small building blocks that fill out real conversations, our guide on telling time in Japanese is a useful companion.

How SPAIKING helps you apologize with confidence

Reading about gomen and sumimasen is the easy part. The hard part is producing the right one, at the right politeness level, in the half second a real situation gives you. You can know the whole table cold and still freeze when you actually step on someone's foot, because knowing a phrase and being able to say it under pressure are two different skills. That gap between recognizing an apology and producing it live is exactly what SPAIKING is built to close.

With SPAIKING, you have a spoken conversation with an AI partner that talks back, so you can rehearse these apologies in realistic situations before you ever need them. You practice calling a server with sumimasen, apologizing to a friend with gomen ne, giving a formal moushiwake arimasen, and answering a stranger's apology with daijoubu, all out loud, as many times as you like. Because the AI responds in real time, you get the two-way pressure a phrasebook can never give you: a reply you did not script, that you have to understand and answer on the spot.

The parts that make it fit learning apologies in particular:

• It is judgment-free. You can fumble sumimasen ten times and the AI just keeps going, which is what finally gets nervous learners to say these words out loud instead of only reading them.
• It corrects you in real time. Your own ear forgives your own pronunciation, so you miss it. Live correction tells you when your sumimasen or your moushiwake arimasen is off and helps you fix it in the moment.
• It is always available. No waiting for a language partner. When you want to drill the difference between gomen and sumimasen until it is automatic, you can do it right now, in a spare five minutes.
• It builds the situational reflex. By practicing whole scenarios, not isolated words, you train yourself to reach for the right politeness level automatically, which is the whole game with Japanese apologies.

Think of this guide as the map and SPAIKING as the practice ground. The phrases here tell you what to say and when; speaking them out loud with a partner that answers back is what turns them into words you can actually produce when a real moment arrives. You can start on the pricing page and begin turning gomen and sumimasen from things you recognize into things you can say without thinking.
