How to say "batch" in Japanese
Choosing the right word
- 一括いっかつnoun, suru verb, transitive verbCovers the sense of dealing with several things at once as a single group — handling, paying, or sending them in one go. This is the everyday word when 'batch' means 'all together at once'.
- nounA loanword used chiefly for 'batch' in computing, as in batch processing or batch files. For computer-related batch work, this is usually the word you want.
- nounUsed in manufacturing for a batch or lot of goods produced together under the same conditions. Natural in factory and quality-control talk, not in everyday conversation.
- 回分かいぶんnoun, prenominal modifierA technical term for batch processing, especially in chemical engineering and manufacturing, contrasting with continuous processing. Seldom the word for general uses of 'batch'; keep it to technical writing.
Use 一括 for lumping things together and handling them as one group, 「バッチ」 for computing, 「ロット」 for production lots, and 回分 mainly in technical batch processing contexts.
