Five major Japanese corporations have signed a basic agreement to develop a new regional industry model built on the local production and consumption of clean energy — with the initial rollout to begin in the Tohoku region.

ERA Co. Inc. (JERA), JERA Cross Co. Inc., Sumitomo Mitsui Banking Corp. (SMBC), Sumitomo Mitsui Finance and Leasing Company, Ltd. (SMFL), and Yanmar Holdings Co. Ltd. (Yanmar) announced Thursday that they will collaborate to boost productivity, decarbonize agriculture, forestry and fisheries, and stimulate regional economies through green transformation (GX).

The initiative aligns with the Ministry of Agriculture, Forestry, and Fisheries’ Basic Plan for Food, Agriculture and Rural Areas, which seeks to accelerate decarbonization and enhance value-added production in rural sectors through public-private partnerships.

Under the agreement, the companies will combine clean energy and advanced technologies to reshape Japan’s primary industries. Key areas of collaboration include the adoption of electric equipment for rice and sake production, powering land-based aquaculture systems with renewable energy, and utilizing agricultural robots and other digital transformation (DX) tools. The partners also plan to develop virtual power plant projects that integrate offshore wind energy with electric agricultural machinery.

The firms aim to create a framework that enables high-value agricultural and marine products — produced using local natural capital and clean energy — to be sold at fair market prices. Through this, the consortium seeks to build a new sustainable model for agriculture and aquaculture that reduces environmental impact while enhancing profitability and regional economic vitality.

The study of the regional vision and full-scale development work will begin in Tohoku before expanding to other areas.
