Japanese Keigo: Complete Guide to Honorific Language

Keigo (敬語 — literally “respectful language”) is the system of honorific speech that permeates formal Japanese. It is not a layer you add on top of Japanese; it is a completely different vocabulary and set of verb forms that replace casual equivalents depending on who you are speaking to and what you are speaking about.

Most learners encounter keigo for the first time at JLPT N4 or N3 level. Full business-level keigo — where mistakes genuinely cause awkwardness or offence — is an N2 concern. This guide covers everything you need: the three types, the 10 most important verb pairs, the most common mistakes, and a practical framework for when to use which form.

Why keigo matters

Japan has a highly contextualised social hierarchy expressed through language. Using casual speech with a customer is not merely impolite — it signals a fundamental lack of professional competence. Using the wrong keigo form (humble form when you should use respectful form, for example) is similarly jarring for a Japanese interlocutor.

Keigo is not optional for professional Japanese. It is mandatory for:

The three types of keigo

1. 尊敬語 (Sonkeigo — Respectful speech)

Sonkeigo elevates the actions and status of the person you are speaking to or about. When you use 尊敬語, you are linguistically raising the other person's actions. It is used for customers, clients, bosses, teachers, or anyone socially above you.

部長はもうお帰りになりましたか?Has the department manager already gone home? (お帰りになる = respectful form of 帰る)
先生はいらっしゃいますか?Is the teacher here? (いらっしゃる = respectful form of いる/いく/くる)

2. 謙譲語 (Kenjougo — Humble speech)

Kenjougo lowers the speaker's own actions and status, showing humility. When you use 謙譲語, you are linguistically lowering yourself and your actions to elevate the other person by contrast. It is used for your own actions when speaking to social superiors.

私がご説明いたします。I will explain. (いたす = humble form of する)
明日伺います。I will visit tomorrow. (伺う = humble form of いく/くる/聞く when directed at a superior)

3. 丁寧語 (Teineigo — Polite speech)

Teineigo is the standard polite register — the ます/です form you learned early in Japanese study. It is not about raising or lowering social status; it is simply a neutral formal register used in most professional and public contexts. Most learners use this without realising it is technically part of keigo.

今日は天気がいいですね。The weather is good today, isn't it? (です — polite form)

10 essential keigo verb pairs

These are the irregular keigo verbs that cannot be derived from regular rules. They must be memorised. They are tested at N3, N2, and N1.

Plain form尊敬語 (for others)謙譲語 (for yourself)丁寧語
する (to do)なさるいたすします
いる (to be/exist)いらっしゃるおるいます
いく (to go)いらっしゃる / おいでになるまいるいきます
くる (to come)いらっしゃる / おいでになるまいるきます
いう (to say)おっしゃるもうす / もうしあげるいいます
もらう (to receive)いただくもらいます
あげる (to give)さしあげるあげます
くれる (to give [to me])くださるくれます
食べる/飲む (to eat/drink)めしあがるいただく食べます/飲みます
知っている (to know)ご存知だ存じる知っています

Regular keigo formation (お/ご + verb stem + になる)

For verbs not in the irregular list above, you can often form 尊敬語 with the pattern お/ご + verb stem + になる:

お読みになる (to read — respectful)読む (to read) → お読みになる. Used for someone else reading: 部長がお読みになった (the manager read it)
ご連絡ください (please contact us)連絡する → ご連絡. Sino-Japanese words (ご + noun) follow this pattern.

For 謙譲語, the regular pattern is お/ご + verb stem + する/いたす:

お持ちします (I will carry it — humble)持つ → お持ちします. Appropriate when doing something for a customer or superior.

Common keigo mistakes

Mistake 1: Using 尊敬語 for your own actions

Wrong

私はいらっしゃいます。

Right

私はおります。

いらっしゃる is 尊敬語 — it elevates the other person. Using it for yourself is the most common and most serious keigo error.

Mistake 2: Double respectful speech

Wrong

部長がおっしゃられました。

Right

部長がおっしゃいました。

おっしゃる is already 尊敬語 for 言う. Adding られる (another respectful marker) is double-respectful — grammatically incorrect and sounds unnatural.

Mistake 3: Using いただく for giving (not receiving)

Wrong

お客様にカタログをいただきます。

Right

お客様にカタログをお渡しします / さしあげます。

いただく is the humble form of もらう (receive). When giving something to a customer, use さしあげる (humble give) or お渡しする.

Mistake 4: Mixing registers in the same sentence

Wrong

部長が来る予定はいらっしゃいますか?

Right

部長がいらっしゃる予定はありますか?/ 部長はいらっしゃいますか?

Respectful forms must be consistent throughout the clause referring to the person being respected. Mixing plain and respectful forms in the same clause sounds incoherent.

Frequently asked questions

What is keigo in Japanese?

Keigo (敬語) is the system of honorific language in Japanese. It has three types: 尊敬語 (respectful speech about others), 謙譲語 (humble speech about yourself), and 丁寧語 (standard polite speech).

Keigo is required in business settings, formal emails, customer service, meetings, and with social superiors (teachers, bosses, clients).
