Translation guide
In Japanese, expressing cooperation depends on the context: mutual effort, formal collaboration, or simply helping out. The most common word is 協力 (kyouryoku), but other expressions like 協調 (kyouchou) for harmony, 連携 (renkei) for coordination, and 手伝う (tetsudau) for helping are also used. Note that direct translations can sometimes sound stiff; Japanese often prefers softer, indirect expressions.
Expressing that people work together to achieve something, often in work, projects, or community activities.
The most common and versatile word for cooperation. It implies joint effort and can be used in both formal and informal settings. Often used with する to mean 'to cooperate'.

While 手伝う is natural for helping, it may not convey the mutual aspect of 'cooperation' as strongly as 協力.

協力 is the broadest term for working together. 協調 emphasizes harmony and smooth relationships. 連携 is about coordination between separate groups or systems. Choose based on whether you want to stress joint effort, harmony, or linkage.
English 'cooperation' can sometimes be translated too directly as 協力, which may sound stiff in casual situations. Consider using softer expressions like 手伝う or 一緒にやろう (let's do it together) when appropriate.
これを終わらせるには協力が必要だ。
We need to cooperate to finish this.
