Since our founding in 1955, Hiyoshi has consistently operated under our corporate philosophy of being “Society-oriented company, technology-oriented company” (A company cannot exist unless it contributes to society, and it can only contribute to society through its technology), and have dedicated ourselves to building a company that earns the trust of society through continuous contributions. Thanks to your unwavering support, we are proud to celebrate our 70th anniversary.
As an “Environmental infrastructure company indispensable to society”, Hiyoshi began with the domestic waste collection and has expanded over the past 70 years into waste treatment, water supply and sewerage facility management, analytical testing, sales of industrial chemicals, and various construction services. Under the key concepts of “measure, observe, protect, and create” we deliver one-stop environmental infrastructure services that contribute to a sustainable society. Prioritizing safety and quality, we are committed to providing reliable services and products while continuously striving to earn and uphold your trust.
In addition, we are working to create a positive and inclusive work environment where all employees can thrive. We actively promote diversity and inclusion and are committed to fostering a culture that values growth and well-being for both our employees and society.
Today, we are united across the company in deepening our core businesses, accelerating digital transformation, investing in people, and pursuing new fields, all as part of a forward-looking capital investment strategy. Looking ahead, we will strengthen our contributions to social infrastructure through initiatives such as the circular economy and W-PPP (Water-Public Private Partnerships), aiming to enhance the quality and efficiency of public services. Additionally, in response to pressing social issues like an aging population and declining birthrates, we are also deepening our collaboration with local communities and actively engaging in regional contribution activities. Furthermore, with a clear sense of responsibility as essential workers, we remain steadfast in our commitment to being a company that grows together with the communities we serve.
In order to contribute to society and create a future where people and nature coexist in harmony from a global perspective, Hiyoshi will continue to practice “Yonpo-Yoshi,” which means “Good in four directions”: Good for Society, Good for the Buyer, Good for the Seller, and Good for the Next Generation (Future). Our aim is to become a 100-year “environmental infrastructure company indispensable to society,” capable of responding to diverse changes in society. All employees will work as one to achieve this goal.
