共きょう同どう責せき任にん

noun

joint responsibility; shared liability

Refers to responsibility shared among multiple parties, often in legal, business, or group contexts. The gloss 'solidarity' is a less common translation and can be misleading; the core meaning is shared accountability.

• このプロジェクトの失しっ敗ぱいは、チーム全ぜん員いんの共きょう同どう責せき任にんです。

  The failure of this project is the joint responsibility of the entire team.

• 共きょう同どう責せき任にんを明めい確かくにするために契けい約やく書しょを作さく成せいした。

  We drew up a contract to clarify the shared liability.
