“すみません: Sumimasen”: A Common Japanese Expression for Apologies, Thanks, and More

As Japanese learners, what words do you find yourself using often? Is it “ありがとう: Arigato” or “こんにちは: Konnichiwa”? One of the words Japanese people use most often in daily conversations is probably “すみません: Sumimasen.”

Some learners may wonder why the expression “Sumimasen” can convey so many different meanings, as it is used in various situations. For example, it can be used when calling a store employee, thanking someone who has given directions, or apologizing after accidentally bumping into someone.

In fact, the phrase “Sumimasen” is not only used for apologies. It carries a deeper sense of consideration for others and the feeling of being sorry. This article explains three main uses of this phrase—apologizing, expressing gratitude, and getting someone’s attention—along with examples.

“Sumimasen” originates from the verb “済む (sumu),” which means “to finish” or “to be settled.” The expression “sumi-masen” literally conveys the idea that something is “not finished” or “cannot be settled with this alone,” expressing the feeling that “this is not enough” or “I am sorry.”

Therefore, “Sumimasen” carries more than just an apology. It includes feelings such as:

・ having caused inconvenience to someone
・ having made someone go through extra effort
・ having placed a burden on someone

This is why Japanese people may use “Sumimasen” in situations where English speakers might simply say “Thank you.” In addition, since “Sumimasen” is a polite expression, it can be used in a wide range of situations, including when speaking with someone for the first time or in business settings.

The most basic use of “Sumimasen” is as an apology. It is used when someone has caused inconvenience to another person or made a mistake.

This is used in situations such as:

・ when being late
・ when forgetting a promise or an arrangement
・ when making a mistake or being wrong
・ when accidentally stepping on someone’s foot

In these situations, “Sumimasen” is used in the same way as “Gomen nasai,” which means “I’m sorry.” While “Gomen nasai” can be used casually as “Gomen,” “Sumimasen” carries a more polite nuance.

Speakers choose different expressions depending on the situation and their relationship with the other person. For example, friends may say “Gomen!”, teachers may be addressed with “Sumimasen,” and customers may be spoken to with “Moushiwake arimasen.”

“Sumimasen” can also be used to express gratitude, which may surprise some foreign learners. For example, when someone helps carry their luggage, Japanese people often say “Sumimasen” in addition to “Arigatou gozaimasu.” But why use an apology when expressing thanks?

This is because Japanese people often feel a sense of apology when someone spends their time and effort helping them. As a result, the expression carries both gratitude and a sense of apology.

In this way, “Sumimasen” is used in situations such as:

・ when receiving help from someone
・ when making someone wait
・ when someone goes out of their way to come for them
・ when someone offers their seat

In these situations, it is perfectly natural to say “Arigatou gozaimasu.” However, it is not unusual for native speakers to say “Sumimasen” together with “Arigatou gozaimasu,” especially when someone has taken their time or made an extra effort to help. In this way, Japanese people often use “Sumimasen” to express consideration and thoughtfulness toward others.

“Sumimasen” can also be used to get someone’s attention. This usage is similar to the English expression “Excuse me.”

Here are some common situations where “Sumimasen” is used to get someone’s attention:

When calling a store employee:
Sumimasen. Chūmon o onegaishimasu.
 — Excuse me. I’d like to place my order.

When asking for directions:
Sumimasen. Eki wa dochira desu ka?
 — Excuse me. Which way is the station?

When getting off a train:
Sumimasen. Orimasu.
 — Excuse me. I’m getting off.

When passing through a crowded area:
Sumimasen. Tōrimasu.
 — Excuse me. Coming through.

“Sumimasen” used in the situations introduced above carries a sense of consideration, conveying the feeling that the speaker may be taking up someone’s time, causing inconvenience, or asking for extra effort. In Japan, approaching strangers and asking for help can be considered a burden because it requires their time. Therefore, it is natural for Japanese people to begin with “Sumimasen.”

The phrase “Sumimasen” is a very useful expression; however, it does not mean that it can be used in every situation.

For example, when giving a formal apology to a supervisor or a customer after making a mistake, “Mōshiwake gozaimasen” is more appropriate than “Sumimasen.” Although “Sumimasen” sounds polite, it carries a slightly casual nuance, making more formal expressions necessary in situations that require a higher level of politeness.

On the other hand, when apologizing to a friend, “Gomen” or “Gomen ne” may sound more natural, even though these expressions are relatively casual. Using “Sumimasen” with someone close may create a sense of distance or make the other person feel uncomfortable. 

Furthermore, when someone lets others go ahead or when asking someone in front to move in order to get off a train, “Sumimasen” is the most natural expression to use. On the other hand, when entering or leaving a meeting room, “Shitsurei shimasu” is generally used and is more appropriate. In this way, although “Sumimasen” and “Shitsurei shimasu” are similar expressions, the situations in which they are used are slightly different.

Japanese native speakers naturally choose between these expressions depending on the situation and their relationship with others. At first, it may seem challenging, but by encountering “Sumimasen” in TV shows, anime, and real-life conversations while paying attention to how it is used, learners will gradually begin to notice the differences.

In Japanese, there are many expressions with different meanings and nuances, like “Sumimasen,” which was introduced in this article. “Sumimasen” is often translated as “I’m sorry” in textbooks; however, in real-life conversations, it is also commonly used to mean “thank you” or “excuse me.” By mastering these different uses, communication with native speakers can become smoother and more natural.
