外人
がいじん
gaijin
= a foreigner; an outsider (a casual, sometimes loaded, shortening of 外国人)
外人 is the short, casual word for a foreigner, and it carries a quiet weight: depending on who says it and how, it can sound like neutral shorthand or like a line drawn between us and them.
外人 means a foreigner or outsider. It is a clipped, informal version of the neutral 外国人 (foreign-national person). In everyday speech many use it without ill intent, but because it literally frames someone as an outside person and has a history of marking non-Japanese as other, it can feel exclusionary. The more polite and safe choice in careful or formal speech is 外国人.
As a learner, prefer 外国人 in polite, public, or written contexts; reserve 外人 for understanding what you hear rather than as your default word. Many foreigners living in Japan find 外人 grating because it can imply permanent outsider status, while plenty of Japanese speakers use it innocently. Reading the speaker’s tone and setting matters more than the word alone.
外 means outside or external, and 人 means person, so 外人 reads literally as outside person. The fuller, more neutral term 外国人 inserts 国 (country) to give foreign-country person. Dropping that 国 is what makes 外人 both more casual and, to some ears, more bluntly othering.

Everyday use
近所に外人さんが引っ越してきて、すごく親切なんだ。

Casual / Social Media
ずっと日本に住んでるのに外人って呼ばれると、ちょっと寂しいよね。
Zutto Nihon ni sunderu no ni gaijin tte yobareru to, chotto sabishii yo ne.
Being called a gaijin even though you’ve lived in Japan forever feels a little lonely, doesn’t it?
The debate around 外人 is really a debate about belonging. Because the word frames a person as outside, some non-Japanese residents, even those born or long settled in Japan, hear it as a reminder that they are seen as guests rather than members of society. Media outlets often prefer 外国人, and adding the polite 外人さん softens the term, which shows speakers sensing its rough edge.
At the same time, intent varies enormously. A child pointing out a 外人 is usually just noting difference, and many speakers use the short form purely out of habit, not hostility. This gap between how the word is meant and how it can land makes 外人 a useful lesson for learners in how vocabulary carries social history beyond its dictionary definition.
