Translation guide
The English word 'librarian' refers to a person who works in a library. In Japanese, the most common and natural equivalent is 司書 (ししょ), which specifically means a professional librarian. However, depending on context, other terms like 図書館員 (としょかんいん) or simply referring to the person by their role may be used. This guide covers the main ways to express 'librarian' in Japanese, from formal titles to casual references.
