How to say "venture" in Japanese

Choosing the right word
  • 事業じぎょうJLPT N1approx.Common
    nounCovers 'venture' in the commercial sense: the general word for a business or enterprise. Use it when 'venture' means a business undertaking or commercial activity rather than a risky gamble.
  • 冒険ぼうけんJLPT N3approx.Common
    noun, suru verb, intransitive verbPrimarily 'adventure'; as 'venture' it suggests a risky, daring undertaking or gamble. It is not the word for a business venture — use it when the emphasis is on daring and risk.
    何なんの冒険ぼうけんもしないなら、何なんも得えられない。↗
    Nothing ventured, nothing gained.
  • nounThe loanword, covering 'venture' as in venture business: a new, risk-taking company. It is the natural choice for that business sense, but it is not a verb and does not mean 'adventure'.
    Our company is a small but elect venture business that assists in entry and totalling of questionnaires.
  • 投機とうきCommon
    nounCovers 'venture' as speculation: a risky financial undertaking, essentially gambling on stocks or markets in hopes of profit. Use it for a speculative venture, not for business or adventure generally.
    彼かれは投機とうきに手てを出だして財産ざいさんの大半たいはんを失うしなった。↗
    He lost the greater part of his fortune in speculation.
  • 冒すおかすCommon
    godan verb, transitive verbThe verb 'to venture' in the sense of braving or risking danger — braving a storm, facing a peril. It describes the act of exposing yourself to risk, not an undertaking or business.

For a business venture use 事業, for the loanword behind venture business 「ベンチャー」, for financial speculation 投機, for a risky adventure 冒険, and for the verb 'to brave or risk' 「冒す」.
