敬語
けいご
keigo
= honorific / polite speech
敬語 (keigo) is Japanese’s built-in system of grammatical respect — a layered set of verb forms, vocabulary substitutions, and sentence endings that signal the speaker’s relationship to the listener or the person being discussed. Unlike adding “please” in English, keigo rewires entire sentence structures depending on whether you are elevating someone else or humbling yourself.
Keigo divides into three distinct registers that learners must treat separately:
尊敬語 (sonkeigo) — honorific language — raises the actions and status of the person you are speaking to or about. The verb 食べる (taberu, to eat) becomes 召し上がる (meshiagaru), used only for superiors, never for yourself.
謙譲語 (kenjōgo) — humble language — lowers your own actions to show deference. The same concept of eating, when referring to yourself in a formal context, becomes いただく (itadaku). You use kenjōgo to describe your own behavior, not others’.
丁寧語 (teineigo) — polite language — is the foundational register built around the です/ます (desu/masu) verb endings. It is neutral and does not elevate or humble anyone; it simply marks the speech as formal and appropriate for non-intimate settings such as shops, offices, or new acquaintances.
Mixing registers incorrectly — for example, using sonkeigo to describe your own actions — is one of the most common and conspicuous errors non-native speakers make.
The hardest part of keigo for learners is not memorizing the forms — it is knowing which direction to apply them. A common mistake is saying ご覧になってください (go-ran ni natte kudasai) to ask a colleague to look at something, when the humble いただけますか (itadakemasu ka) or a plain お願いします (onegaishimasu) would be more appropriate depending on rank. Remember: sonkeigo goes UP toward others; kenjōgo comes DOWN from yourself.
Another frequent error is over-using keigo with close colleagues or friends, which can sound cold or sarcastic. Japanese workplace culture expects keigo with clients and seniors but teineigo or even plain form (タメ口, tameguchi) among peers of equal standing. Reading the room — called 空気を読む (kuuki wo yomu) — is as important as knowing the grammar itself.
敬語 is written with two kanji that directly state its function. 敬 (kei) means “respect” or “reverence”; its left component 攴 (puku, to strike lightly) historically depicted a ritual act of deference, while the right side 苟 reinforces the idea of earnest care. 語 (go) means “language” or “speech,” composed of 言 (gen/koto, words) on the left and 吾 (go, I/self) on the right — together suggesting “one’s own words.” The compound 敬語 therefore literally reads as “respectful speech,” encoding its purpose into the very characters used to write it.

Keigo is inseparable from Japan’s concept of social hierarchy, known as 上下関係 (jōge kankei) — the vertical ordering of relationships by age, rank, tenure, and context. Mastery of keigo is considered a marker of professional readiness: graduating students entering the workforce are routinely enrolled in keigo training before their first day, and the inability to switch registers fluently is seen as a lack of social maturity rather than merely a language gap.
The boundaries of keigo shift with industry and region. High-end department stores and traditional ryokan inns use an especially elevated hospitality register called 接客敬語 (sekkyaku keigo) — service honorifics — that even native speakers from other professional backgrounds sometimes find unfamiliar. Phrases like いらっしゃいませ (irasshaimase, welcome) and よろしかったでしょうか (yoroshikatta deshō ka, was everything all right?) are hallmarks of this register and are studied as a distinct professional skill in Japanese service training curricula.
For non-native learners, the expectation around keigo is more forgiving in casual or tourist settings, but the gap becomes significant in professional contexts. Learners who invest in keigo — even imperfectly — signal genuine respect for Japanese social norms, which is often met with visible appreciation by Japanese colleagues and clients.
