What Is Keigo — And Why Does It Matter?
Keigo (敬語) is the formal, honorific register of Japanese. It's not just a set of polite words — it's a structured system that reflects Japan's deep cultural emphasis on hierarchy, respect, and social awareness. Whether you're job-hunting, working in a Japanese company, or simply trying not to accidentally offend someone, understanding keigo is essential.
At its core, keigo is divided into three distinct sub-systems, each serving a different social function.
The Three Systems at a Glance
| System | Japanese | Direction of Respect | Who It Refers To |
|---|---|---|---|
| Sonkeigo | 尊敬語 | Elevates the other person | The listener or a third party |
| Kenjōgo | 謙譲語 | Lowers yourself | The speaker (you) |
| Teineigo | 丁寧語 | Polite neutral register | The speech itself (tone) |
Sonkeigo: Elevating Others
Sonkeigo (尊敬語) is used when talking about or to someone of higher status — your boss, a customer, a teacher, or a respected elder. It literally "elevates" the subject by using special honorific verb forms and vocabulary.
Key Sonkeigo Verbs
- いる → いらっしゃる — to be/exist (honorific)
- 言う → おっしゃる — to say (honorific)
- する → なさる — to do (honorific)
- 食べる/飲む → 召し上がる — to eat/drink (honorific)
- 来る → いらっしゃる/おいでになる — to come (honorific)
Example: 社長はもういらっしゃいますか？ — "Has the president arrived yet?"
Kenjōgo: Humbling Yourself
Kenjōgo (謙譲語) works in the opposite direction — instead of raising someone else, you lower yourself in order to show deference. It's used when describing your own actions in relation to a social superior.
Key Kenjōgo Verbs
- いる → おる — to be (humble)
- 言う → 申す — to say (humble)
- する → いたす — to do (humble)
- 食べる/飲む → いただく — to eat/drink (humble)
- 行く/来る → 参る — to go/come (humble)
Example: 私が資料をお持ちいたします。 — "I will carry/bring the documents."
Teineigo: The Polite Baseline
Teineigo (丁寧語) is what most learners study first: the ～ます/～です verb endings. Unlike the other two, teineigo doesn't shift who is being elevated or lowered — it simply raises the politeness level of the speech itself. It's appropriate for strangers, acquaintances, service interactions, and professional contexts where a full keigo register isn't required.
Example: これはおいしいです。 — "This is delicious." (polite, neutral)
How They Work Together
In real conversation, these systems often overlap. A sentence might use sonkeigo to refer to your boss's action, kenjōgo for your own action, and teineigo endings throughout. The key is to never mix up the direction — never use sonkeigo to describe your own actions, and never use kenjōgo to describe your superior's actions.
A Simple Rule to Remember
- Talking about what someone important does? → Sonkeigo
- Talking about what YOU do for them? → Kenjōgo
- Just want to sound polite in general? → Teineigo
Master these three distinctions and you'll have a solid foundation for navigating Japanese professional and social environments with genuine confidence.
