Always attentive to growers’ needs and aspirations, AGRO-KANESHO shows the way forward

On February 4, 2025, we, AGRO-KANESHO Co., Ltd., took a new step forward as a group company of Idemitsu Kosan Co., Ltd. As a core company in the agribusiness of the Idemitsu Kosan group, we will utilize its management resources and continue to accelerate grower-centric approach of sales and technical promotion activities and product development, while adhering to the management philosophy “With Always Growers,” which we have held since our founding.
The “Soil Analysis and Diagnosis Services” launched in 2015 has steadily increased the number of samples and has come to meet the expectations of a wide range of growers. The “Kanesho Farm” is an initiative to solve problems together with growers facing various challenges by utilizing our expertise in crop protection products and know-how on enhancing the natural fertility of the soil at the regional trial farms and communities, thereby contributing to the regional agriculture and regional economy. We hope to continue to be of service to as many growers and agricultural production corporations as possible.
After the Fukushima plant was shut down due to the Great East Japan Earthquake disaster in 2011, diversification of production bases and stable supply of products have been our major challenges. Following the establishment of the Ibaraki Plant in 2013, we opened the Yamaguchi Plant in Hofu, Yamaguchi in November 2018. In 2024, a new building for the "Department of Applied Formulation Technology Research" was completed on the premises of the Yamaguchi plant. We will strengthen the production base and optimize the logistics function, while aiming to supply the highest quality products.
As for our global business, we are currently achieving steady growth every year by deploying and penetrating the technical promotion capabilities of crop protection products based on what we have accumulated in Japan.
We will continue to contribute to the safety and stable supply of food, which is indispensable for human beings, through development of market and environmentally friendly products and implementation of technical promotion, targeting both domestic and global markets.
