Japanese Keigo Explained:
Types, Examples & Baito Keigo

You have heard it before. You walk into a convenience store in Japan and the staff say something that sounds far more elaborate than a simple greeting has any right to be. Then you try to politely ask a question and the words come out wrong — not grammatically wrong, just wrong for the room. That gap is keigo.

The system has a reputation for being impenetrable, and that reputation is mostly earned. But it is learnable in stages. Beginners can stop at recognition. Intermediate learners can master the core verb swaps. Advanced learners spend years calibrating the density. This guide covers all three stages — plus a dedicated section on baito keigo, the grammatically dubious phrases you hear at every family restaurant chain in Japan, which have their own search volume and their own interesting story. If you are working on your spoken output alongside the written forms, the guide to speaking Japanese is a useful companion.

Keigo at a Glance

What Is Keigo? (敬語)

敬語けいご (keigo) — the kanji break down as 敬けい (respect) and 語ご (language). So: respectful language. But calling it "polite Japanese" undersells the structure. Keigo is not just adding a please or a sorry. It is a distinct vocabulary layer with its own verb forms, its own prefixes, and its own internal logic about whose actions are being described and who is in the room.

Standard Japanese (and most languages) has one word for "to go." Keigo has three: 行く (iku) for plain speech, いらっしゃる (irassharu) when the person going is someone you respect, and 参る (mairu) when you are the one going and you want to signal humility. Same concept, three different words depending on the social geometry of the situation.

Uchi and Soto: The Rule That Confuses Everyone

Before covering the three types, one concept unlocks the entire system: 内うち (uchi) and 外そと (soto).

Uchi is your in-group: your company, your team, your family. Soto is anyone outside that group: clients, other companies, strangers. The rule is straightforward — when you speak to someone in the soto, you humble everyone in your uchi, regardless of their actual rank.

This is why, when a receptionist tells a client "the president is out of the office," they say 社長しゃちょうの田中はただいま外出がいしゅつしております — using humble language for the president, despite the president being higher ranked than the receptionist. To the client, the president is uchi, and uchi gets humbled. Using sonkeigo for your own boss in front of a client is one of the most common keigo errors at N3 level.

丁寧語ていねいご (Teineigo): Where Everyone Starts

If you have studied any Japanese, you already use teineigo. It is the polite register built on two endings: です (desu) after nouns and adjectives, and ます (masu) after verb stems. It does not elevate or humble anyone — it simply signals to the listener that you are treating this as a formal enough situation to speak politely.

Teineigo is what you use with classmates you have just met, with shop staff when you are the customer, and in most public service situations. It is the baseline of adult Japanese outside of close friendships.

尊敬語そんけいご (Sonkeigo): Elevating Their Actions

Sonkeigo is used when describing what a respected person does. A customer orders. Your boss decides. A teacher speaks. The action belongs to someone above you in the current social context, and sonkeigo marks that relationship.

The most common pattern is replacing a standard verb with its sonkeigo equivalent. These are not guessable from the plain form — they are a separate vocabulary set that you memorize. If you need a refresher on how Japanese verbs conjugate in the first place, the Japanese verb conjugation guide covers the foundations before keigo complicates things.

謙譲語けんじょうご (Kenjougo): Lowering Your Own Actions

Kenjougo is the counterpart to sonkeigo. Where sonkeigo elevates the other person's actions, kenjougo lowers yours. It is how you signal, through verb choice, that you understand the social direction: they are above, you are below, and you are acting toward them.

The kenjougo logic also governs your in-group when speaking to outsiders. When you tell a client "our president will go," you use 参まいります (mairimasu) — the humble form — not いらっしゃる. Your president is still in your uchi relative to the client.

Which Keigo Type to Use: The Decision Guide

Most errors come down to one question: whose action is this? Run through these three checks before speaking in any business or formal situation.

High-Frequency Keigo: The Phrases You Will Actually Use

You do not need to memorize every verb in the chart above to function in Japan. About 80% of real keigo use comes from a short list of high-frequency phrases tied to specific situations. Here is where they appear. Restaurant and shop settings are where beginners encounter sonkeigo most — our Japanese restaurant phrases guide covers the ordering side from the customer's perspective.

The Gradient of Requests

Most learners stop at 〜てください (te-kudasai) because it is polite enough for everyday situations. In business settings, though, even grammatically correct direct requests can read as abrupt. Japanese business communication prefers indirection as the request gets higher-stakes.

The pattern is consistent: the more formal the request, the less it sounds like a request and the more it sounds like an expression of the speaker's personal feelings.

Cushion Words (クッション言葉くっしょんことば)

Correct grammar can still land badly if it is too direct. Cushion words are the softeners that sit at the start of a sentence to prepare the listener for a request or refusal. Omitting them in business settings is one of the subtle markers that identifies someone as not yet comfortable in formal Japanese — the keigo grammar is right, but the sentence opener gives it away.

Baito Keigo (バイトけいご): The Keigo That Isn't Really Keigo

Spend a week in Japan and you will hear this. You go to a family restaurant, order something, and the server says something like 「1000円になります」 — "It will become 1,000 yen." Which is odd, because the price is not transforming. It already is 1,000 yen. Or you get: 「ご注文の方、以上でよろしかったでしょうか」 — "Was your order this?" — using past tense to ask about an order you just placed. If you are heading to Japan and want to know what to expect on the other side of the counter, the Japanese travel phrases guide covers what you actually need to say as a customer.

This is baito keigo (バイトけいご) — literally "part-time job honorifics." The term became common in the early 2000s as chain restaurants and convenience stores standardized their customer service through employee manuals. The manuals were attempting to teach keigo to staff with no prior training, and the result was a set of phrases that feel polite but are grammatically wrong by traditional standards.

Baito keigo is not a recognized formal category in the Japanese grammar system. Linguists sometimes call it マニュアル敬語 (manyuaru keigo — manual keigo). Most Japanese adults recognize it as an error. Most also accept it without reacting, because it appears everywhere and its intent is clear enough. You will not offend anyone by using it. But if you understand why it is wrong, you understand a useful piece of the real keigo system.

Advanced Keigo: Calibration, Density, and Written vs. Spoken

At N2 and above, the core grammar is mostly handled. The challenge shifts from "which verb form" to "how much keigo." Too little reads as rude or unprofessional. Too much is its own problem — excessive keigo creates distance and, in some contexts, reads as passive-aggressive. The goal is calibration, not maximum formality. If you are preparing for the N3 grammar exam, the keigo patterns in this section are among the most frequently tested items.

Keigo Density by Relationship

Spoken vs. Written Keigo

This one catches N3 learners who have learned to speak but not write formal Japanese. Several common spoken keigo words become wrong or childish in written form. Business emails have their own register that diverges from what you would say on the phone.

The させていただく Controversy

させていただく (sase-te-itadaku) — causative + humble receive — means "I receive permission to do..." The pattern has become a kind of keigo all-purpose softener. You will hear it constantly. Most grammarians say it is overused.
