Japan Organic Agriculture Research Association was formed as a organization to seek the ideal way of farming in 1971. In the early days organic agricultural tecnology was not established so that the organic agricultural productivity was very low. But now many of organic farmers has reached high productivity level. One of the principles of organic agriculture is the use of a cultivation method designed for improving fertility instead of chemical fertirizers and pesticides. So an alternative to conventional agricultural methods founded in organic agriculture such as land fertility increased by various organic materials and the land eco-system presearved by proper cropping. Especially land utilization system has an important key. In fact, many of organic farmers adopt the way of planting many crops about 50 varieties and mixed cropping, rotation cropping are adopted too. And once in two or three years, paddy-upland rotation is adopted. As a result, the organic farmers have gained stable productivity and livelyhood. This land utilization system is able to described the organic high intensive rotation system with paddy-upland rotation. To extend steadily oraganic agriculture, it needs to establish not only the technology to increase land fertility by organic materials but also the new land utilization system. So that it is necessary to organize the co-partnerships between organic producers and consumers.
