Keigo in Japanese: a clear guide to honorific language for intermediate learners
You can read keigo. You see お待ちしております at the end of an email, you recognize いらっしゃいませ when you walk into a shop, and you know なさる is the respectful version of する. Then someone asks you to actually write a message to a professor, or you have to answer the phone at a part-time job, and your mind goes blank. The polite Japanese you learned from your textbook, the です・ます you can produce without thinking, suddenly feels like it is not enough.
That gap is where most learners get stuck. Keigo is not a single set of rules you memorize once. It is a system for adjusting how you speak based on who you are talking to and who you are talking about, and the hard part is rarely the vocabulary. It is knowing which form to reach for, and when.
This guide walks through what keigo is, the three forms most learners start with, the official model that goes one level deeper, the social logic (uchi and soto) that decides which form you use, and a practical answer to the question almost nobody addresses: how do you actually learn keigo well enough to use it.
What is keigo?
Keigo (敬語, "respectful language") is the honorific language system in Japanese, a set of grammatical forms and specialized vocabulary used to express respect, humility, or politeness depending on your relationship to the listener and to the people you are talking about. It is woven deep into Japanese culture and Japanese society as a kind of social lubricant: the right keigo signals that you understand your place in a social interaction, and using it well helps establish trust and build relationships.
The Japanese language gives you a sliding scale. Casual speech, the plain dictionary form you use with close friends and family members, sits at one end. The most polite, honorific language sits at the other. Most of daily life happens somewhere in between, and the skill of speaking Japanese well is moving fluidly along that range to convey respect at the right level for each context.
One mechanical point that explains a lot of what follows: casual language uses the plain dictionary form (する, 食べる, 行く), while keigo uses either the polite -masu form or, for many common verbs, an entirely different specialized verb. That single shift, from dictionary form to a more polite form, is the engine of the whole system.
The three types of keigo
The standard classroom model divides keigo into three main types: teineigo, sonkeigo, and kenjougo. Almost every introduction you will read, including this one, starts here because it is the most practical way in.
Teineigo (丁寧語): the polite form
Teineigo is the polite language you already know. It is the です・ます register, the polite speech that uses the -masu suffix on verbs and です on nouns and adjectives. 食べます (tabemasu, "eat"), します (shimasu, "do"), 学生です (gakusei desu, "I am a student"). Even おはようございます (good morning) is teineigo at work, a polite-form greeting you have used since your first week of studying Japanese.
Teineigo is the baseline of polite Japanese, the register you use with strangers, acquaintances, and anyone you are keeping a polite social distance from. If you have finished a beginner textbook, you have teineigo.
A quick clarification, because it trips people up: teineigo is a type of keigo, not a separate thing from it. When someone says "I can't speak keigo," they usually mean they cannot yet produce the next two forms.
Sonkeigo (尊敬語): the respectful form
Sonkeigo is the respectful form that elevates the listener, or whoever you want to show respect to, by raising their actions. You use it when the other party is the subject of the verb: your boss, a client, a teacher, a customer, anyone of high rank or anyone you are honoring.
Some verbs take honorific prefixes or a polite pattern (お + verb stem + になる). Others change into entirely different words. Here are the common verbs you will meet first:
| Plain (dictionary form) | Sonkeigo (respectful form) | Meaning |
|---|---|---|
| する | なさる (nasaru) | to do |
| 食べる / 飲む | 召し上がる (meshiagaru) | to eat / drink |
| 行く / 来る / いる | いらっしゃる (irassharu) | to go / come / be |
| 言う | おっしゃる (ossharu) | to say |
| 見る | ご覧になる (goran ni naru) | to see |
The お + stem + になる pattern is worth its own example: お腰かけになってください (o-kake ni natte kudasai) means "please sit down," a respectful way of inviting someone to take a seat. The grammar is honoring the listener's action, not the speaker's.
Kenjougo (謙譲語): the humble form
Kenjougo is the humble form. Instead of raising the other person, it lowers you, or your in-group, to show respect by contrast. You use it for your own actions when speaking to someone you want to honor.
| Plain (dictionary form) | Kenjougo (humble form) | Meaning |
|---|---|---|
| する | いたす (itasu) | to do |
| 食べる / 飲む | いただく (itadaku) | to eat / drink / receive |
| 行く / 来る | 伺う (ukagau) / 参る (mairu) | to go / come |
| 言う | 申す / 申し上げる (mousu / moushiageru) | to say |
| 見る | 拝見する (haiken suru) | to see |
The humble form of "to do" is itasu, and in real polite speech you will almost always meet it as いたします (itashimasu): お待ちいたします (I will wait), お願いいたします (please [do this for me]), お持ちします (I will carry it). In each case the speaker's own action is humbled. The respect flows to the listener because you have lowered yourself.
The single most common mix-up among learners is using sonkeigo for your own actions, which accidentally elevates yourself, or using kenjougo for the other person, which lowers them. The rule to hold onto: respectful form for their actions, humble form for yours.
The official model: five categories
The three-type model is the right place to start, but it is not the full picture, and this is where most English-language guides stop. In February 2007, the Agency for Cultural Affairs (文化庁) published an official guideline, the 敬語の指針 (Keigo no Shishin), that reorganizes keigo into five categories rather than three.
The guideline splits kenjougo into two, and splits a piece off teineigo:
- 尊敬語 (sonkeigo) — respectful language, raising the other party's actions. Same as above.
- 謙譲語Ⅰ (kenjougo I) — humble language directed at a specific person you are honoring (伺う, 申し上げる, お持ちする).
- 謙譲語Ⅱ / 丁重語 (kenjougo II / teichougo) — "courteous" language that humbles your action in general, without a specific honored target. 参る (to go), 申す (to say), おる (to be) belong here. This is why 明日大阪に参ります works even when no single person is being honored: you are speaking courteously to the listener, not lowering yourself toward a third party.
- 丁寧語 (teineigo) — the です・ます politeness register.
- 美化語 (bikago) — "beautification" language, the honorific words formed with the polite prefix お or ご that simply make speech more refined: お茶 (tea), お水 (water), ご飯 (rice/meal). These do not honor anyone in particular. They just elevate the tone.
You do not need the five-category model to function. But it explains things the three-type model leaves murky, like why 参る and 伺う are both "humble" yet behave differently, and it is the model Japanese speakers are taught when they study keigo formally. If you have ever been confused about 謙譲語, this is usually why.
Uchi and soto: the social logic behind keigo
Here is the part that makes keigo click, and the part that pure verb tables never explain. Which form you choose does not only depend on rank. It depends on group.
Uchi (内, "inside") is your in-group: your company, your team, your family. Soto (外, "outside") is everyone else: clients, other companies, strangers. When you speak to someone in the soto, you humble everyone in your own uchi, including people who outrank you. Keigo, at this level, is really a tool for marking social distance and the Japanese hierarchy of relationships in the moment.
This is why you humble your own boss when talking to a client. Inside the office, your section chief is 部長 and you use sonkeigo about them. But on the phone with a customer, you say 田中は席を外しております (Tanaka is away from their desk), dropping the honorific title and using the humble おる, even though Tanaka is your superior. To the client, your boss is part of your uchi, so your whole in-group lowers itself together.
Once you see keigo as a way of drawing and redrawing the line between in-group and out-group, the verb choices stop feeling arbitrary. You are not just being polite. You are positioning yourself and your group relative to the person in front of you.
When do you have to use keigo, and when is です・ます enough?
A fair question, because the honest answer is that full sonkeigo and kenjougo are not required in most everyday interactions. Teineigo, the です・ます polite form, carries you through the large majority of daily life: shops, casual acquaintances, classmates, most service interactions where you are the customer.
Where the heavier forms become necessary is the formal setting and work: business Japanese, speaking with clients, job hunting, emails to professors, meetings, phone calls on behalf of a company, anything where you are in service to the other party. Even a simple 失礼します (shitsurei shimasu, "excuse me / I'll be going") marks the shift into a more formal register as you enter or leave a room. If you use Japanese professionally in Japan, keigo is not optional. If you are mostly reading and watching content, you will meet keigo constantly in business settings, formal speeches, and customer-facing dialogue, and being able to parse it matters even before you need to produce it.
And one reassurance worth stating plainly: most Japanese people tend to be forgiving of foreigners who get keigo wrong. Native speakers grow up absorbing it by observing adults, and even they make mistakes; baito keigo (the slightly-off keigo of part-time workers) is a whole documented phenomenon. Aim for understanding first, then production. Nobody expects a non-native speaker to use keigo correctly on day one.
How do you actually learn keigo?
Tables are useful for understanding the system. They are close to useless for retention. You will not remember that 拝見する is the humble form of 見る because you read it in a chart. You will remember it because you met it in a real email, looked it up, and then saw it again three more times over the following weeks, across different contexts.
That is the real bottleneck. The set verbs and phrases (伺います, 申し上げます, ご覧ください, お世話になっております) do not stick from a single exposure. They stick from repeated encounters in context, which means the most effective thing you can do is read real Japanese where keigo actually lives, business news, company sites, formal announcements, customer-service writing, and keep the words you meet.
This is the loop immit was built for. immit is a popup Japanese dictionary that runs on any web page: you hover over a word and a popup shows the headword, its reading in furigana, the part of speech, a definition, an example sentence, and audio you can click to hear it. It supports JP-EN, EN-JP, EN-EN and JP-JP monolingual lookup, so you can read a keigo-heavy page without breaking your flow to switch tabs. When you meet a specialized verb like 召し上がる or いらっしゃる, one click saves it into a built-in 8-stage SRS that brings it back for review at spaced intervals until it sticks. There is also a Pocket Dictionary, a small dictionary window you can pin to the page and read alongside your text, with active search and review built in. If you want to try it, you can add the extension (free, no account).
Frequently asked questions
What is keigo in Japanese?
Keigo (敬語) is the honorific language system in Japanese: a set of grammatical forms and specialized vocabulary used to express respect, humility, or politeness depending on your relationship to the listener and the people you are speaking about. It is essential in formal situations and business Japanese, and built into everyday Japanese speech as a way of acknowledging social standing.
What are the three types of keigo?
The three main types are teineigo (丁寧語), the polite です・ます form; sonkeigo (尊敬語), the respectful form that raises the other person's actions; and kenjougo (謙譲語), the humble form that lowers your own actions to show respect.
What is the difference between sonkeigo and kenjougo?
Sonkeigo raises the listener by elevating their actions (なさる, 召し上がる, いらっしゃる), so you use it for what the other person does. Kenjougo lowers you or your in-group (いたす, 伺う, 申し上げる), so you use it for your own actions. The respect lands on the listener either way; the difference is whose action you are describing.
When do you have to use keigo, and when is です・ます enough?
Teineigo (です・ます) is enough for most daily interactions: shops, classmates, casual acquaintances. Full sonkeigo and kenjougo become necessary in formal situations and at work, such as speaking with clients, job hunting, or representing a company on the phone.
Is teineigo the same as keigo?
Teineigo is one type of keigo, not a separate category. It is the polite form (です・ます). Keigo as a whole also includes the respectful (sonkeigo) and humble (kenjougo) forms, plus, in the official model, courteous language and beautification.
What is the uchi/soto rule, and why do you humble your own boss?
Uchi (inside) is your in-group; soto (outside) is everyone else. When you speak to someone in the soto, you humble your entire uchi, including superiors. That is why you drop your boss's honorific title and use humble forms about them when talking to a client: to the outsider, your boss is part of your group.
Do Japanese people expect foreigners to use perfect keigo?
Generally, no. Most Japanese people tend to be forgiving of learners who get keigo wrong, and even native speakers make mistakes with it. Understanding keigo when you read or hear it comes first; producing it well comes with exposure and practice.
How do I actually remember keigo verbs and set phrases?
Repeated exposure in real context, not memorizing tables. Read Japanese where keigo appears (business writing, formal announcements, customer-facing text), look up the set verbs you meet, and review them on a spaced schedule so they come back until they stick. A lookup-and-save loop like immit's turns each encounter into a card you will see again.
