Meanings

  • To stay at home to supervise a residence and any pets or belongings during an absence.
  • Refers to the person who performs that duty, such as a family member or a hired house-sitter.
  • Describes the duty as a temporary or security-related obligation rather than a permanent profession.

Etymology

留守 (rusu) means absence or being away; (ban) means watch or turn; when combined, 留守番 denotes a person who stays behind to guard the home in someone else’s absence; the reading rusuban reflects a standard kun-readings pairing.

Composition

  • 留 = stay, remain; 守 = guard, protect; 番 = watch, turn; When combined, the sequence conveys the act of staying behind to monitor a residence in someone’s absence.

Usage

Used as a noun that can take をする to express performing the duty; common in family contexts with children or pets; casual speech uses 留守番をする or 留守番になる; in writing, it can appear in explanations of household routines or security arrangements.
💡 Tips
Mnemonic: think of 留守番 as a small guardian who stays home to watch over what’s inside; the three parts literally map to stay, guard, watch, so visualizing a guardian at the doorway helps recall the meaning.

  • 不在 (fuzai) — absence, away
