How to say "Cooperation" in Japanese

When translating "cooperation" into Japanese, you must choose carefully between 提携 and 連携. In Japanese, 提携 (ていけい (teikei)) is typically associated with "cooperation, tie-up, collaboration, business alliance" (Syllabus Level: N2) and represents 複数の組織や企業が共通の目的のために協力関係を結ぶこと。業務上の協力関係を指すことが多い。When multiple organizations or companies form a cooperative relationship for a common purpose. Often refers to business cooperation.. On the other hand, 連携 (れんけい (renkei)) maps to "cooperation, coordination, link-up, liaison" (Syllabus Level: N2) and represents 複数の個人や組織が密接に連絡を取り合い、協力して物事を行うこと。チームワークや情報共有のニュアンスが強い。Multiple individuals or organizations closely communicating and cooperating to achieve something. Strong nuance of teamwork and information sharing.. A literal translation of "cooperation" can often sound unnatural to native Japanese speakers if mixed up!
