Company information
Hiyoshi Corporation provides comprehensive support for environmental projects 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 activities related to the environment, 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" (biological testing methods) using organisms developed by Hiyoshi, such as genetically modified cells, to measure environmental conditions. Furthermore, based on the belief that "environmental issues have no borders," we have been accepting 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 anticipate that activities to realize business expansion based on our established achievements will become more active. Hiyoshi aspires to contribute to the international community with greater efforts and innovation to ensure safety and security in global living conditions.
