Introduction: The Linguistic Architecture of Respect
Keigo (敬語 / polite/honorific language) is the formal register of Japanese that is used in professional contexts, with strangers, with elders, and in any situation requiring explicit expression of social respect. It is not merely a matter of adding "please" or using formal vocabulary — keigo involves a completely different set of verb forms, vocabulary items, and grammatical structures that transform the way actions, states, and relationships are expressed.
Japanese children learn basic keigo in school; full proficiency typically develops through early professional experience. Foreign Japanese learners who achieve conversational fluency often describe keigo as the point at which Japanese becomes genuinely difficult — not because the concept is hard but because the required vocabulary and form-changes are extensive and culturally specific.
The Three Levels
Keigo formally divides into three systems:
Teineigo (丁寧語 / Polite Language)
The most basic level — the suffix です (desu) and the verb form 〜ます (masu) that is taught to foreign learners as "polite Japanese." Appropriate for most formal and semi-formal contexts between relative equals.
- Example: The verb "to eat" (食べる / taberu) becomes 食べます (tabemasu) in teineigo.
Sonkeigo (尊敬語 / Respectful Language)
Used to elevate the actions of the person you are speaking to (or about) — when referring to what a senior person, customer, or respected figure does, specific elevated verb forms and vocabulary replace the standard.
- Standard: 食べる (taberu / to eat) → Sonkeigo: 召し上がる (meshiagaru) Standard: 言う (iu / to say) → Sonkeigo: おっしゃる (ossharu) Standard: 来る (kuru / to come) → Sonkeigo: いらっしゃる (irassharu)
Kenjōgo (謙譲語 / Humble Language)
Used to lower your own position (or your in-group's position) when speaking to a social superior — the reverse of sonkeigo.
- Standard: 食べる → Kenjōgo: いただく (itadaku) Standard: 言う → Kenjōgo: 申す (mōsu) Standard: 行く (iku / to go) → Kenjōgo: 参る (mairu)
Why This Matters Culturally
The keigo system's existence reflects a fundamental feature of Japanese social organization: relationships are not equal by default. Every interaction involves a determination of relative social position — age, company hierarchy, customer/service provider relationship — and language is one of the primary mechanisms for acknowledging and maintaining these positions.
The customer as emperor (お客様は神様 / okyakusama wa kamisama): The service industry's famous customer-is-always-right philosophy in Japan is reflected in the keigo used toward customers — the sonkeigo/kenjōgo combination creates a linguistic asymmetry where the service provider consistently elevates the customer while lowering themselves, producing the distinctive Japanese customer service register that foreign visitors experience as exceptionally deferential.
Practical Implications for Visitors
Foreign visitors are not expected to use keigo and will not be judged for its absence — the expectation is simply that non-native speakers use whatever Japanese they have, and the accommodation is given freely. However, some basic honorific vocabulary is worth knowing:
Itadakimasu (いただきます): Said before eating, expressing humble receipt of the food — the most commonly heard humble form in daily Japanese life.
O-negai shimasu (お願いします): "Please" in a request context — the kenjōgo form that is the standard polite request expression.
Sumimasen (すみません): "Excuse me / I'm sorry" — the most useful single phrase for foreign visitors, appropriate for getting attention, apologizing for minor inconveniences, and expressing various forms of social regret.
