Keigo basics: polite, humble, and honorific Japanese without fear

Keigo (敬語) — Japanese honorific language — has a fearsome reputation, and even native speakers get formal training in it when they start their first job. Here's the reassuring truth: the system has only three parts, the truly irregular vocabulary fits in one table, and as a learner you need far less of it, far later, than you probably think. What you do need early is the ability to recognize keigo, because shop staff and station announcements use it at you constantly. This guide gives you the three-part map, the essential irregular verbs, and the workplace phrases worth knowing.

1. The three types of keigo

The direction metaphor solves most confusion: sonkeigo points up at what the respected person does; kenjougo points down at what you do. You never use sonkeigo about yourself, and you never use kenjougo about the customer. Teineigo is neutral and stacks with both — 召し上がります is sonkeigo + teineigo at once. And a key cultural rule: it's about in-group vs out-group (うち/そと), not just rank — when talking to a customer about your own boss, your boss counts as in-group, so you humbly say 田中は参ります ("Tanaka will come"), dropping even the -さん.

2. Good news: you already speak keigo

If you finish sentences with です and ます, you're already using 丁寧語 — the foundation layer of keigo taught from the first page of every textbook, and the register covered by the JLPT N5 and N4 vocabulary. For travel, classroom Japanese, and everyday conversation with strangers, teineigo alone is completely appropriate. Nobody expects sonkeigo from a learner ordering ramen. The next two layers matter when relationships become asymmetric: customers, bosses, professors, job interviews.

3. The regular patterns (before the irregulars)

Most verbs form sonkeigo and kenjougo with simple templates — the irregular table in the next section is the exception list, not the system:

• Sonkeigo template: お + ます-stem + になる → 読む becomes お読みになる ("[the professor] reads"). 社長はもうお帰りになりました。(しゃちょうは もう おかえりに なりました) — "The president has already gone home."
• Sonkeigo shortcut: the passive form doubles as an honorific — 読まれる, 行かれる. Less deferential than お〜になる, very common in offices.
• Kenjougo template: お + ます-stem + する → 持つ becomes お持ちする ("I'll carry [it for you]"). お荷物をお持ちします。(おにもつを おもちします) — "I'll carry your luggage." With Sino-Japanese nouns: ご + noun + する → ご案内します ("I'll show you the way").

4. The essential irregular pairs — one table to memorize

A small set of everyday verbs replace themselves entirely instead of using the templates. These are the highest-frequency words in service and office Japanese, so this one table is the core investment of keigo study:

Notice いらっしゃる covers be, go, and come — one word, three meanings, resolved by context. Also note a small conjugation quirk: いらっしゃる, おっしゃる, なさる, and くださる form their ます-forms with い — いらっしゃいます, おっしゃいます, なさいます (not ×いらっしゃります). You've heard this a thousand times already: いらっしゃいませ, the shop greeting, is just いらっしゃる in imperative-polite clothing.

5. お and ご — the beautifying prefixes

The prefixes お and ご (both written 御 in kanji) add politeness to nouns, usually the listener's things. The split follows word origin:

• お + native Japanese words (kun-yomi): お名前 (おなまえ, your name), お水 (おみず, water), お仕事 (おしごと, your work), お店 (おみせ, shop).
• ご + Sino-Japanese words (on-yomi): ご住所 (ごじゅうしょ, your address), ご家族 (ごかぞく, your family), ご質問 (ごしつもん, your question), ご連絡 (ごれんらく, contact).
• Common exceptions that take お despite being Sino-Japanese: お電話, お料理, お時間, お勉強. And some words carry お/ご almost permanently, with no honorific force left: お茶 (tea), お金 (money), ご飯 (rice/meal).
• Don't beautify your own things when the prefix marks respect: ask for the listener's お名前, but give your own 名前. (Exception: fixed kenjougo formulas like お願い and ご連絡します are correct because they're directed at the other person.)

6. When do beginners actually need keigo?

1. Now (recognition only): understand いらっしゃいませ, 召し上がりますか ("will you eat here?"), ご覧ください ("please look") — clerks and announcements aim sonkeigo at you all day. You reply in plain です/ます; that's the expected exchange.
2. Around JLPT N4–N3: the irregular table above starts appearing in exam questions — grammar sections love 召し上がる vs いただく. Study it alongside the N3 word list.
3. When you work in Japanese: job interviews, customer-facing roles, and business email demand active sonkeigo/kenjougo. This is also the register the JPT tests heavily — see the JPT module and the JLPT vs JPT guide if that's your path.

7. Workplace phrases you'll hear (and need) constantly

8. Common keigo mistakes

• Double keigo (二重敬語): stacking two honorifics on one verb — ×おっしゃられる, ×お召し上がりになられる. One layer is correct: おっしゃる, 召し上がる. (Native speakers slip here too.)
• Honoring yourself: ×私が召し上がります. Your own eating is いただきます — which is exactly why you say いただきます before meals: "I humbly receive."
• ご苦労様です to a superior. It's what bosses say to subordinates. Upward, always use お疲れ様です.
• 了解しました to clients or bosses. Common between peers, but 承知しました / かしこまりました are the safe upward forms.
• Keigo with friends. Using 召し上がりますか over drinks with classmates creates comic distance. Matching the register to the relationship is the skill — plain form with friends is not "rude Japanese", it's correct Japanese.

9. A realistic study plan

Treat the irregular pairs as vocabulary, not grammar: eleven rows, learned like any other words. Add them to your review deck and let spaced repetition do the work; drill the readings — めしあがる, うかがう, はいけんする — the way you'd drill any new verb, checking anything uncertain in the dictionary. Then spend your listening practice in service situations (convenience store videos, restaurant scenes) actively naming what you hear: "that was sonkeigo, aimed at me." Recognition first, production later. A steady daily session plus the word modules will carry the vocabulary side; the politeness instincts follow from exposure.
