The han operates much like a buying club. Members place weekly group orders that are delivered to a convenient central location where members can pick-up their food supplies. The hans are almost exclusively run by women. The han serves as the hub for all cooperative activities. It is composed of approximately 10 members living in close proximity to each other.
Members meet a minimum of once per month.
Meetings deal with member requests and complaints, consumer protection issues, and environmental and peace movement activities. Han members also test food products. In recent years, the Japanese economy has slumped amidst political and financial market instability. The country's population is aging and an increased number of Japanese women are joining the workforce. The government has relaxed regulations, reducing prices for food.
