How to say "warranty" in Japanese
Choosing the right word
- 保証ほしょうnoun, suru verb, transitive verbThe word for a warranty in the product sense: a maker's or seller's assurance that an item is sound and will be repaired or replaced if it fails, as with appliances or electronics.
- 保険ほけんnounChiefly means insurance. As a rendering of 'warranty' it is marginal: it fits only the loose, figurative sense of a safeguard or back-up protection against something going wrong, not the product warranty.
For a product warranty — a maker's promise to repair or replace a faulty item — use 保証; 保険 normally means insurance and covers 'warranty' only in the loose sense of a safeguard.
