(模合, Mo-ai) means "meeting for a common purpose". It originated in Okinawa, Japan as a way for villagers to support each other through social, financial, health, or spiritual interests.

Moais are social support groups that can help people develop a sounding board and live with purpose. Research suggests that close relationships are more important than money or fame for happiness and longevity. People in moais can help each other through life's ups and downs, and can even help each other stay engaged and achieve more.
