無休 means "no days off" and is used almost exclusively in business or service contexts to indicate that an establishment operates every day.
WORD FORMATION:
The prefix 無 (without, no) + 休 (rest, holiday). This 無～ pattern appears in many words: 無料 (free of charge), 無限 (infinite), 無理 (impossible).
COMMON EXPRESSIONS:
- 年中無休: open year-round, no holidays (most common usage)
- 定休日なし: no regular closing day (similar meaning, used on signs)
- 24時間営業、無休: open 24 hours, every day
USAGE:
You will often see 年中無休 written on signs outside shops, restaurants, and convenience stores. It is not used to describe people (e.g., not "I work without days off").
