留学

The term refers specifically to the act of residing in a foreign country for the purpose of academic study. It is distinct from a simple vacation (旅行) or a business trip (出張), as the primary objective must be education at a school, university, or language center.

In practical usage, it is frequently paired with the verb "suru" (留学する) to function as a verb meaning "to study abroad."

Depending on the duration and nature of the program, it is often modified by specific prefixes. For example, "tanki ryugaku" (短期留学) refers to short-term study, while "kōkan ryugaku" (交換留学) refers to an exchange program between two institutions.

While it generally carries a positive connotation of self-improvement and global experience, it can also imply a significant financial and emotional commitment, often involving a period of adjustment to a new culture.
