How to say "concentration" in Japanese
Choosing the right word
- 集中しゅうちゅうnoun, suru verb, transitive verb, intransitive verbFocusing your attention on a task — the mental-concentration sense, as when studying or working. This is the word you want for mental focus.
- 濃度のうどnounHow concentrated a substance is in a solution or mixture — its strength or density, as measured in chemistry. This is about strength, not mental focus.
- 精進しょうじんnoun, suru verb, intransitive verbReally means diligent devotion to a pursuit — single-minded effort and dedication — rather than concentration of attention. For plain mental focus this is seldom the word you want.
- 濃縮のうしゅくsuru verb, transitive verb, no-adjectiveThe act or process of concentrating something — making a solution stronger or richer, as in condensing or enriching it. Use this for the operation itself, while 濃度 describes the resulting strength.
- 結集けっしゅうnoun, suru verb, transitive verb, intransitive verbGathering efforts or forces together and marshalling them toward a common aim — the 'concentration of forces' sense. It has nothing to do with attention or solutions.
Use 集中 for mental focus on a task, 濃度 for how strong a solution is, 濃縮 for the act of concentrating it, 結集 for marshalling efforts or forces, and 精進 chiefly for diligent devotion.
