Meanings

  • Hand-wash for garments: the instruction or action of washing clothing by hand rather than by machine.
  • Clothing care label term indicating a delicate or manual wash cycle.
  • A small dedicated sink or station specifically intended for washing hands in workplaces or public venues (distinct technical nuance from full bathroom facilities).

Origin

The term entered common modern usage as indoor plumbing and Western-style sanitation spread in Japan from the late 19th century (Meiji era) onward; as public buildings, schools and railways adopted sinks and restrooms, the compound was used in signage and manuals to label both the act and the installed fixtures.

Composition

  • 手 (te) — “hand”, the body-part element.
  • 洗 (arai from arau) — “wash”, indicating the action or process.
  • Combined they form a compound literally meaning “hand-wash,” used both for the act of washing hands and for places/fixtures for washing hands.

Usage

Used widely across registers: on public signage, facility maps, and in spoken requests; a polite variant appears in formal contexts while the plain form appears in casual speech and on appliance or clothing-care labels; it labels sinks in restaurants, stations, hospitals, and domestic bathrooms and identifies the hand-washing option on laundry instructions.
💡 Tips
Remember it by splitting into te (hand) + arai (wash): picture your hands under running water and say tearai to recall both the action and the sink/place.
