Our Vision

Establishing of Yamadaya International - 2013


At YAMADAYA, we are dedicated to the contribution of improving the health of our customers.  For the past years, we have been educating our customers about rice. This experience has deepened our own understanding as we realize that ricefields have a biological diversity.


If rice fields decrease in number, environmental issues will increase.  In order to conserve the rice fields as well as contributing to help solve world-wide food crisis, Yamadaya is working with local farmers to export premium quality rice.

Currently, approximately 30% of the rice fields in Japan are not allowed to be cultivated because of the rice acreage reduction policy.  If these rice fields are re-used for other crops, it wouldn’t matter.  However, if these rice fields are left in poor conditions and abandoned because villagers grow old or leave the village, it would be hard to cultivate them once more and may even become irrepairable.  

(The rice acreage reduction policy is in effect as it is for adjusting national demand and maintaining the price stability.)


However, cultivating rice for export is allowed as long as it doesn’t affect the national demand.  Our vision is provide a new channel for the farmers in Japan through YAMADAYA International.  We hope to protect the biodiversity and carry on the regional cultures and customs by planting and selling rice which have been produced in the rice fields under the rice acreage reduction policy.  If you purchase our “environmental preservation rice”, the rice producers will feel hopeful about the future and it will also develop the next generation of agriculture workers.


We are really appreciated with your corporation.
