An Introduction to Japanese Keigo

Last Updated on 12.08.2022 by Coto Japanese Language School

The word keigo (敬語) is written with the kanji that means “to respect” (敬) or “to admire” and the kanji for “language” (語). Japanese society has always cared for hierarchy to the point that honorific speech seems to be a whole other language. If you’re planning to build a fulfilling career in Japan, knowing business Japanese will help you stand out during your job search.

Whatever the reason you are studying Japanese, we believe you were having fun. You enjoyed writing your first hiragana and katakana. Gradually, you were able to express yourself and hold a steady casual conversation in Japanese. Or, at least, that was at the beginning.

As you reach for the intermediate step, the fun fades away and you are shaking your head with despair as you try to understand Japanese honorific speech.

So in this article, we’re guiding you through all the nooks and crannies of Japanese keigo — from the viewpoint of a non-native. We’ll discuss the honorific forms, humble forms, conjugations and phrases.

Introduction to Japanese Keigo

Do you know that Japan had a caste system in the past? Until the Meiji restoration, people in different castes would not speak the same Japanese as a form of respect for social ranks. Despite the disappearance of the caste system, honorific speech is still used to mark the degree of intimacy or social standing between people.

To use keigo is to show your consideration and respect for a person older than you or someone with a higher social standing. Age isn’t the only factor. It can be based on a different position or experience in a company, like your senpai (someone who’s more senior). Your speech will differ accordingly to the person in front of you: a friend, a colleague, a chief or a client; and to whom you a referring to yourself, your friend, colleague or client.

But don’t believe keigo speech is easier for native speakers, too. Japanese kids learn keigo the hard way, as they enter junior high school and are confronted with the Japanese hierarchy. Suddenly, they have to mark the difference between 先輩 (elder students) and 後輩 (junior students).

If the thought of learning a whole new style of speaking Japanese sounds scary then you are not alone. Memorizing keigo is a challenge for even Japanese people so it’s good to know that we’re all in the same position. Very often, Japanese people will not learn keigo in school, but during intensive training sessions before they start their first job.

The Concept of Uchi and Soto

To better understand respectful speech, take a peek into the Japanese concept of uchi and soto, or “in-out” (内-外). The idea might seem simple: uchi (内) literally means “inside”, while soto (外) means “outside”. But both words aren’t just about the physical position. They’re used to describe social distance too.

The concept of uchi and soto shapes Japan’s culture. In sociology and social psychology, there is the concept of “in-group” and “out-group”, and the Japanese society takes this matter more seriously — so seriously, in fact, that it plays a significant role in its language.

Basically, an in-group is the social group that you identify as a member of. Out-group, on the other hand, is a group that doesn’t fall into the in-group.

In Japanese, 内 means home. As a concept, uchi (内) reflects in-group and refers to all the people you know inside a specific social circle: your family, your company and your club. For example, inside the 内, family members may drop the title.

In Japanese, soto (外) is the culture’s equivalent to out-group. As a concept, 外 refers to all the people who are not inside your specific social circle. For example, another company’s employee or team rival.

So why are these concepts important in Japanese keigo? Japan, like many Eastern countries that tend to be collectivists, follows the rough idea that conformity in society is more important — the opposite of more individualistic views of Western culture.

In other words, being part of a group is an important element in Japan. Japanese speech differs depending on the social context of what you define as your in-group at the moment.

In-group can go as small as your family and span to a country. Think of the concept of “us” and “them”. This dynamic concept affects social interactions and is reflected in the Japanese language. So keep in mind that you will not use honorific words when speaking about insiders (people from your social circles) to outsiders.

Japanese Keigo for Beginners

Before you actually dive into keigo, you will probably learn the polite verb forms, otherwise known as teinei (丁寧/ていねい). This consists of the stem of a verb and what is called the ~ます form. For example, the verb “to see”, る, becomes ます.

Keigo covers both humble form, kenjougo (謙譲語), and polite form, sonkeigo (尊敬語), with various levels of vocabulary and expressions. This written Japanese offers even more complexity.

When you start to have a good command of Japanese, you will realize that politeness in Japanese is of great importance when dealing with elders or working in a professional environment. You will learn to adjust your speech depending on whether you have a certain intimacy with someone or to emphasize the social rank disparity if you are in a higher position.

But what if you want to show even more respect to someone? After all, humility is a big part of Japanese culture, in work or social life. Take a look at the table below to see three different levels of “politeness”.

Omiyage o moratta
Omiyage o moraimashita
Omiyage o itadakimashita.

One of our students joked that a good rule of thumb is this: the longer the sentence become, the more polite and formal it is. We don’t know if it’s entirely true, but that’s the pattern we see.

Now, you’re most likely to use the casual Japanese form with your in-group — who you have an equal or casual relationship with. This can be your classmates who you know very well, your close friends, siblings or even parents.

Going up a notch, the formal form is typically used for someone who has more social distance from you: your teachers, coworkers or strangers.

You use the utmost polite Japanese keigo to someone you deem sits on a much higher social hierarch. This demographic falls to people like your managers, boss and, yes, customers or clients.

But remember the “in-group” and “out-group” concepts again? Japanese people, especially women, have a tendency to use keigo even to a stranger, so don’t be surprised if they talk to you in a very humble and honorific language.

Basic Rules of Keigo

Now that we’ve gotten over who we can use keigo and the concept of uchi and soto, we can deal with the real keigo rules. The Japanese language is actually divided into three groups: the polite style, the humble style and the honorific style.

When using keigo, some words can be substituted for a more respectful version. For example, the word あした (tomorrow) and ひと (person) will become あす and かた respectively. This form of speech is called Aratamatta iikata (改まった言い方): formal speech.

The second thing to know is that Japanese honorific prefixes o or go can be added to certain nouns and verbs. The easiest examples is certainly tea, cha which becomes “o-cha” and family, 家族, which becomes ご家族. 

The adjunction of honorifics after names is also a part of the respectful speech. The polite さん, like Tanaka-san (田中さん) becomes Tanaka-sama (田中様).

1. Polite Keigo: Teineigo (丁寧語)

The polite style is the easiest form of keigo ruled by regular grammar with a structure similar to casual speech. Thus, it is the first form of keigo taught to Japanese language learners. So when you are using です and ます instead of the dictionary form, a considerate and formal tone of Japanese, you are already using keigo.

As a reminder, the copula です comes after nouns, adjectives, and adverbs, generally, at the end of a sentence while the suffix ます is added at the end of a verb.

I am going to buy a book.本を買いに行く
Hono kaini iku.
Hono kaini ikimasu.
The phone is broken.携帯(けいたい)が壊(こわ)れた。
Keitaiga kowareta.
Keitaiga kowaremashita.
What is this?これは何だ
Korewa nan da.
Kochirawa nandesuka.

Honorific Keigo: Sonkeigo (尊敬語)

This style is to show respect to someone of higher position, like a superior or a customer, when speaking to them. You should never use 尊敬語 form to refer to yourself. The usage of 尊敬語 is difficult to understand, and characterized by lengthy polite sentences. Whereby, common verbs will change for more polite ones and some will even change into a respectful form.

Sumimasen, tanaka-sensei wa imasuka
Sumimasen, tanaka-sensei wa irasshaimasuka
How was the interview?面接はどうでしたか。
Mensetsu wa dou deshitaka
Mensetsu wa ikaga deshitaka

Humble Keigo: 謙譲語

In the table above, you will find the honorific and humble styles’ special set expressions, along with the polite and casual speech forms.

The following humble set-expressions おります, 参ります, いたします, いただきます, もうします, 存じでおります are part of a third category called 丁重語. This courteous form of keigo is not often referred to and is used when your action does not directly involve the listener, but most likely the person you are talking to is someone to whom you want to be very polite.

I am Sakura. 私はさくらです。
Watashi wa sakura desu.
Watashi wa sakura to moushimasu.
The phone is broken.携帯(けいたい)が壊(こわ)れた。
Keitaiga kowareta.
Keitaiga kowaremashita.
I read the bookこの本を読みました。
Kono hon o yomimashita.
Kochira no hon haitokushimashita.

When referring to yourself, you should be humble. When referring to someone in your inner circle, you should humble them too — because the concept of “in-group” stipulates that they’re part of you too.

The kenjougo (謙譲語) is used to lower your social status when speaking about yourself. It should be used when you are speaking to someone of higher social rank when describing the actions of you or someone of your circle. Like for 尊敬語, the 謙譲語 substitutes verbs with other forms. Nouns may also change: the word 人, previously mentioned, will become 者.

This is particularly important in the Japanese work environment. When you’re speaking directly to your manager, you will probably address them in honorific form — because they’re socially higher than you. Easy, right?

Now, what about when you’re talking to your company’s clients, and suddenly need to mention your managers? To refer to them directly, do you use the humble or honorific form?

The answer is humble form. This is because in that moment, your manager is part of your in-group (uchi) and the client is your soto. An important thing to know is that you “raise” people from your out-group while you lower the peope in your in-group, regardless of the individual’s status from the beginning.

Japanese Keigo Conjugation

For both honorific and humble styles, as seen previously, certain verbs have set expressions. For the verbs without such set expressions, they obey keigo conjugations. The first rule is the adjunction of the polite prefix “o” to the stem of the verb.

We often focus on verbs construction and the social relations between a speaker and a listener, but keigo covers more than set expressions and situational examples. In particular, Japanese language uses honorific prefixes. Most of you might know that the Japanese honorific prefixes お (o) or ご (go) can be added to some nouns and verbs.

When used with a noun, it is preceded by either お (o) or ご (go), but is limited to only nouns which indicate actions (suru verbs). For verb, erase the ます and add になる.

EnglishHonorific Form
Verbお + Verb ます (stem form) + になる
Nounお/ご + Noun + になる



You can essentially add お (o) or ご (go) to any nouns to transform it into honorific form, but be careful. Adding too many prefixes will make your sentences sound awkward — we don’t want you trying tohard, and there are other ways to talk in keigo without putting お before every object.

However, you’ll most likely encounter these words without realizing that they are nouns with honorific prefixes.

EnglishHonorific JapaneseRomaji

For the humble style, the construction of the verb will be as follows: お/ご + stem of the verb + する. You have certainly heard it before in お+願い+します(“please”).

The honorific style can also be expressed with what is called the “easy keigo” with verbs used in the passive form れる or られる. Although said to be easier, this form of keigo can be confused with the passive voice and should be used with care.

29 Useful Japanese Keigo Phrases for Work

The first step is understanding that some kanji readings and some words are different depending on if you are casual or polite. The easiest example is the word “tomorrow”. You’ll learn 明日 is read あした but, as you progress in your Japanese studies, you’ll quickly encounter the reading あす.

When Should I Use Japanese Keigo?

Well, respectful language should be used toward older people, toward distinguished people, and in the workplace. Of course, exceptions exist and that is why keigo is as difficult for native speakers as for learners.

The respectful language can be strictly applied in one company or more loose in another. Foreigners often get slack from the Japanese as they do not expect a non-native to master this speech.

The difficulty also resides in the unknown: a gathering of people you do not know and here you are at loss, not knowing who is eminent, who has your age and who is younger. In some contexts, casual speech is preferred as an ice breaker while Keigo would be considered too distant.

Speaking Keigo As a Foreigner in Japan

While native speakers are expected to use proper keigo (and if they do not, they are seen as unprofessional and will be frowned upon), the same is not always true for non-native speakers. Foreigners are often forgiven for their misuse of keigo and are excused for not having a good command of that high level of Japanese.

That being said, you should do your best to try and learn Japanese keigo. And the best way to master the Japanese honorific is to learn slowly but surely all the ins and out’s of respectful speech.

Keigo is also widely used in the workplace. Check out our business Japanese courses and send us an inquiry if you want to know more about Japanese keigo .
