How to say "investment" in Japanese
Choosing the right word
- 投資とうしnoun, suru verb, transitive verb, intransitive verbThe word for investment in the ordinary financial sense: putting money into stocks, property, or a business with the aim of gain or return. This is what most uses of the English word call for.
- 出資しゅっしnoun, suru verb, transitive verb, intransitive verbInvestment in the sense of putting up or contributing capital to a company or venture, typically as a shareholder or partner; closer to contribution of funds or financing than to investing for personal return.
- 出金しゅっきんnoun, suru verb, transitive verb, intransitive verbRarely the word you want for 'investment': it really means paying out or withdrawing money, and its 'investment' sense is only the marginal idea of money paid out or contributed.
- 投入とうにゅうnoun, suru verb, transitive verbInvestment as the act of committing or pouring in funds — and, by extension, personnel or other resources — into a project or effort; not the usual word for financial investment made for a return.
- 投下とうかnoun, suru verb, transitive verbInvestment in the sense of capital committed or sunk into a venture, market, or project; typical of business and economic writing about funds put into something, rather than everyday talk about investing.
Choose 投資 for the ordinary financial sense of investing money for a return; 出資 for putting up capital in a venture; 投入 for committing funds or resources; 投下 for capital committed to a project; 出金 is really paying out money.
