How to say "responsibility" in Japanese

Choosing the right word
  • 役やくJLPT N3approx.Common
    nounResponsibility in the sense of one's role or assignment — the duties that come with a post in a group or organization. For abstract accountability or blame, this is not the word you want.
    彼かれが重要じゅうような役やくを果はたした。↗
    He played an important part.
  • 責任せきにんJLPT N3approx.Common
    nounThe default word for responsibility as accountability: being answerable for one's decisions, actions, or the people one oversees, including supervision of staff. This is what 'it's my responsibility' calls for.
  • 負担ふたんJLPT N1approx.Common
    nounResponsibility felt as a burden — a load one has to bear, often a financial or practical one. When 'responsibility' means being answerable for something, this is not the natural choice.
    彼かれは、両親りょうしんの負担ふたんになった。↗
    He was a burden to his parents.
  • 義務ぎむJLPT N3approx.Common
    nounResponsibility as obligation — a duty one is bound to perform, whether by law, rules, or moral duty. The emphasis falls on the requirement itself, not on answerability for results.
    このような義務ぎむがあるなんて知しらなかった。↗
    I never knew about such a duty.
  • 責めせめCommon
    nounResponsibility here shades into blame or liability — being the one at fault for something that went wrong. For plain accountability it is seldom the word you want; it is really 'blame'.

Choose 責任 for accountability in the everyday sense; 義務 for obligatory duties, 負担 for responsibilities felt as burdens, 役 for responsibilities attached to a role, and 「責め」 mainly for blame or liability.
