Hiyoshi Corporation provides comprehensive support for environmental business across a wide range of fields, from analysis and measurement to industrial chemicals, facility management, and environmental conservation. With a history spanning half a century and a solid technical foundation, we engage in various environmental-related operations, including environmental analysis, maintenance of environmental infrastructure, sales of industrial chemicals, waste collection and transportation, and road maintenance. Additionally, we create and offer new solutions as part of Hiyoshi's one-stop service. In the future, we are also considering a life innovation business that applies "bioassays" using organisms (such as genetically modified cells) developed by Hiyoshi to measure the environment. Furthermore, based on the belief that "environmental issues have no borders," we have been welcoming over 200 trainees from 20 countries and dispatching engineers for more than 20 years, focusing on human resource development to share Hiyoshi's expertise accumulated over more than 60 years with the world. Moving forward, we expect our activities to become more active in realizing business expansion based on our established achievements. Hiyoshi aspires to contribute to the international community with even greater efforts and innovation to ensure safety and security in global living.
