Message from the President

We are looking for energetic people who will create a new atmosphere.

Thank you for your continued understanding and support of TONETS CORPORATION. 

Since our founding in 1937, TONETS CORPORATION has specialized in the design, installation, and maintenance of air conditioning systems. Building on the technology and expertise we have cultivated over many decades, we have consistently delivered high-quality air conditioning solutions.

Today, we operate in a business environment that is changing faster than ever before. While we face challenges such as the increasing frequency of natural disasters caused by climate change and rising raw material and energy costs resulting from global conflicts, rapid advances in semiconductor technology and AI are accelerating efficiency, automation and autonomous technologies, fundamentally transforming the way we live and work. In particular, continued technological innovation in environmental protection and energy conservation will be essential to achieving a carbon-neutral society by 2050. 

Over the years, we have addressed these challenges through technological innovation. We have achieved world-leading levels of energy efficiency in heating source systems, which account for a significant share of energy consumption in buildings. In fiscal 2022, our Total Optimal Control System for Heating Sources (E-SCAT®) received the Energy Conservation Grand Prize awarded by the Director General of the Agency for Natural Resources and Energy. We have also developed a system integrating 3D laser scanning and BIM to significantly streamline renovation projects—from on-site surveys through design and planning—as well as a variety of applications that improve construction management. Through these innovations, we continue to create comfortable, efficient environments that support both people's daily lives and our customers' business activities while helping to address broader societal challenges. 

We also recognize the physical and mental well-being of our employees as a key management priority. Through our commitment to Health and Productivity Management, we strive to enhance both employee well-being and sustainable corporate growth. By developing people with resilience, integrity, sound judgment, and advanced technical expertise, we aim to build an organization capable of meeting future challenges while responding to increasingly diverse values and work styles.

In 2037, TONETS CORPORATION will celebrate its 100th anniversary. Guided by our corporate philosophy of pursuing harmonious development as a company responsible to the environment, society, and culture, we will continue to strengthen the combined power of our people, technology, and organization. By further advancing the technological excellence that defines TONETS CORPORATION, we are committed to achieving sustainable growth and enhancing our corporate value for the future.
 
We sincerely appreciate your continued support and encouragement.
